Product Introduction

I. Product - related Information

(I) Specification Parameters

YJV and YJY Aluminum Core cables are flexible aluminum Power Cables. Their specification parameters are clearly and carefully set to meet the power transmission needs in different scenarios.

In terms of conductor specifications, such cables cover a variety of cross - sectional sizes, with common ones being 10mm², 16mm², 25mm², 35mm², 50mm², 70mm², etc. Different cross - sectional sizes correspond to different current - carrying capacities. Cables of 10mm² and 16mm² are suitable for small - power power transmission, such as branch power supply in family rooms; cables of 25mm² to 50mm² can be used in medium - load scenarios, such as power distribution in small shops and office buildings; cables of 70mm² and above can cope with large power loads and are applicable to power supply for some production lines in industrial plants, etc.

Their rated voltage is usually 0.6/1kV. This voltage level complies with the standards of low - voltage power distribution systems and can be adapted to common low - voltage power distribution equipment, ensuring that there will be no problems in the power transmission process due to voltage mismatch. At the same time, the insulation thickness of the cable is designed according to the cross - sectional size and rated voltage to ensure that the insulation performance meets the requirements. The XLPE insulation layer has a uniform thickness and can effectively prevent current leakage.

In terms of Flexibility, there are clear regulations on its minimum bending radius, which is generally 10 - 15 times the outer diameter of the cable (there will be differences for different specifications). This parameter ensures that the cable can be properly bent during laying, meeting the installation needs in narrow spaces or complex paths. In addition, the conductor DC resistance of the cable meets relevant standards to ensure the efficiency of power transmission.

(II) Characteristic Uses

YJV and YJY Aluminum Core Cables have a wide range of applications in many fields relying on their own characteristics and can meet the power transmission needs in different scenarios.

In the construction field, these two types of cables are commonly used power Distribution Cables. For ordinary residential houses, YJV cables of 25mm² and below can be used for branch power distribution such as lighting and sockets indoors. Their PVC Sheaths have certain corrosion resistance and can adapt to the indoor environment; in high - rise buildings, YJY cables, due to the good weather resistance of their XLPE sheaths, can be used in relatively complex laying environments such as shafts and corridors for power transmission of main lines to ensure the power supply of the entire building.

In the industrial field, they will be selected in places that have requirements for cable flexibility. For example, in the production workshop of a factory, the equipment layout is compact, and cables need to be laid through the equipment. The flexibility of YJV and YJY aluminum Core Cables enables them to easily cope with such scenarios. For some industrial environments with slight corrosion, the PVC sheath of YJV cables can provide certain protection; for outdoor industrial facilities, such as power distribution for open - air production equipment, the XLPE sheath of YJY cables has obvious advantages in weather resistance and can resist the impact of natural factors such as wind, sun, rain, etc.

In terms of municipal engineering, they can also play a role. In the power distribution lines of street lamps on urban roads, cables of appropriate specifications can be selected according to the power of street lamps. The PVC sheath of YJV cables can adapt to the underground laying environment; in the power distribution of public areas such as parks and squares, the XLPE sheath of YJY cables can maintain stable performance in the outdoor environment, ensuring the power supply of public facilities.

In addition, in the agricultural field, such as power supply for greenhouses and power distribution for farmland irrigation equipment, YJV and YJY aluminum core cables can be selected according to actual load requirements. Their flexibility is convenient for laying in fields or greenhouses.

(III) Material and Style

The material selection and style design of YJV and YJY aluminum core cables are closely related to their performance and uses. The application of each material is carefully considered, and the style is also convenient for practical use.

The conductor is made of aluminum. Aluminum has good conductivity. Although its conductivity is slightly lower than that of copper, it has more advantages in cost and can reduce the overall cost of the cable. At the same time, the Aluminum Conductor has been treated with a special processing technology and has certain flexibility, enabling it to adapt to the needs of bending and laying. The surface of the aluminum conductor has been subjected to anti - oxidation treatment to form a dense oxide film, which can prevent oxidation and corrosion during storage and use and ensure the stability of conductivity.

The insulation layer is all XLPE (cross - linked polyethylene). XLPE forms a three - dimensional network structure through cross - linking reaction, which greatly improves its mechanical strength, aging resistance and chemical corrosion resistance. It has excellent temperature resistance. The long - term allowable working temperature can reach 90℃, and it can withstand higher temperatures during short - term overload. There will be no insulation failure due to excessive temperature during power transmission. Moreover, the XLPE insulation layer has high insulation resistance and small dielectric loss, which can reduce energy loss in the power transmission process.

In terms of sheaths, YJV cables adopt PVC (polyvinyl chloride) sheaths. PVC has good wear resistance, corrosion resistance and flame retardancy, which can protect the insulation layer and conductor inside the cable and adapt to a variety of common environments; YJY cables use XLPE as sheaths. XLPE sheaths are better than PVC in weather resistance, high and low temperature resistance, chemical corrosion resistance, etc., and have a longer service life especially in outdoor or harsh environments.

In terms of style, both types of cables have a multi - core cabling structure. The common number of cores is 4 Cores, 5 Cores, etc. The multi - core structure can meet the needs of power distribution systems such as three - phase four - wire system and three - phase five - wire system. The cable is round as a whole. This structure makes the cable stress evenly during laying, convenient for winding, transportation and storage, and can better adapt to various laying pipes and trunking.

(IV) Production Process

The production process of YJV and YJY aluminum core cables is rigorous and careful. Each link from raw material processing to finished product inspection has strict quality control standards to ensure that the performance of the cable meets the requirements.

The production of the conductor is the first step. High - purity aluminum rods are selected and drawn into Aluminum Wires of the required diameter through a wire drawing process. During the wire drawing process, the wire drawing speed and die precision are strictly controlled to ensure that the diameter of the Aluminum Wires is uniform and the surface is smooth. Then, multiple aluminum wires are stranded in a specific way to form a conductor. During stranding, appropriate tension is maintained to make the conductor structure compact and round, and at the same time, the flexibility of the conductor is enhanced.

The extrusion of the insulation layer is one of the key processes. First, the XLPE particles are dried to remove the moisture in the particles to avoid defects such as bubbles in the insulation layer. The dried XLPE particles are sent to the extruder and melted into a fluid state at high temperature, and then evenly wrapped around the conductor through an extrusion die to form an insulation layer. During the extrusion process, temperature, pressure and speed are accurately controlled to ensure that the insulation layer has a uniform thickness and a smooth surface. After extrusion, the insulation layer is cross - linked, and the XLPE molecules are cross - linked by heating to form a stable structure.

In the cabling link, multiple Insulated Wire cores are stranded into a cable according to a certain pitch. Filling materials are placed during stranding to make the cabled cable round. At the same time, stable tension is maintained during cabling to prevent the wire cores from loosening. After cabling, for YJV cables, the extrusion of the PVC sheath is carried out; for YJY cables, the extrusion of the XLPE sheath is carried out. When extruding the sheath, the process parameters are adjusted according to different sheath materials to ensure that the sheath has a uniform thickness, a flat surface and is closely combined with the cabled wire cores.

In the finished product inspection link, a comprehensive test will be carried out on the conductivity, insulation performance, mechanical performance, etc. of the cable. The conductivity of the conductor is checked through DC resistance test, the insulation effect of the insulation layer is verified through insulation resistance test and voltage withstand test, and the mechanical strength of the cable is inspected through tensile and bending tests. Only cables with all indicators meeting the standards can leave the factory.

II. General Product Information

(I) Packaging

The packaging design of YJV and YJY aluminum core cables focuses on protecting the integrity of the cables during storage, transportation and handling, while taking into account the convenience of packaging and the clarity of identification.

For coiled cables, wooden or metal reels are used for packaging. The diameter of the reel is determined according to the specification and length of the cable to ensure that it can stably carry the weight of the cable. The cable is neatly wound on the reel, and appropriate tension is maintained during winding to avoid loose, Twisted Cables or surface damage caused by mutual friction. Both sides of the reel are equipped with baffles, and the height of the baffles is higher than the winding height of the cable to prevent the cable from sliding during transportation and storage.

The outside of the reel will be tightly wrapped with a plastic film to form a moisture - proof and dust - proof barrier to prevent the cable from getting damp and contaminated with dust. For cables that need long - term storage or are transported to humid areas, a layer of moisture - proof paper will be covered outside the plastic film to further improve the moisture - proof effect.

A clear label is pasted on the baffle of the reel. The label indicates the product name (YJV or YJY aluminum core cable), specification (such as 4 - core 25mm²), length, production batch number, production date, implementation standard, manufacturer name and contact information, etc. At the same time, warning signs such as "Moisture - proof", "Sun - proof" and "Do not press heavily" are also marked on the label to remind relevant personnel to pay attention to protection during handling and storage.

For small batches or short - length cables, solid cartons are used for packaging. Buffering materials such as foam boards and bubble films are placed inside the cartons to prevent the cables from being damaged due to collision during transportation. Relevant product information and warning signs are also marked on the outside of the cartons.

(II) Transportation

The transportation of YJV and YJY aluminum core cables must follow strict specifications to ensure that the cables are not damaged during transportation and their performance is not affected.

The transportation method is selected according to factors such as transportation distance and the number of cables. For long - distance transportation with a large number of cables, railway transportation or road freight is usually used. During railway transportation, the reels are placed stably in the freight carriage, and steel wire ropes or special fastening belts are used to fix the reels at the bottom of the carriage to prevent sliding or tipping during transportation. An appropriate gap is left between the reels to avoid mutual collision. For road freight, trucks with sufficient carrying capacity are selected. The carriage must be flat, clean and free of sharp debris. The fixing method of cable reels is the same as that of railway transportation.

For short - distance transportation or small - batch transportation, logistics vehicles can be used. When loading and unloading cables, special hoisting equipment is used. The hoisting point is selected at the central axis of the reel. Hoisting directly from the side of the reel or the cable roll is strictly prohibited to prevent deformation of the reel or damage to the cable.

The following matters should be noted during transportation: Cables should avoid open - air transportation. If it is unavoidable, they must be covered with waterproof canvas to prevent sun and rain; keep away from fire sources, heat sources and corrosive substances to avoid damage to the cable's insulation layer and sheath; during the driving process of the transport vehicle, drive smoothly, avoid violent operations such as sudden braking and sharp turns, and reduce the impact on the cable; during transportation, regularly check the fixing of the cable and the integrity of the packaging, and deal with problems in time if found.

After arriving at the destination, it is necessary to check the packaging and appearance of the cable together with the receiver, and go through the handover procedures only after confirming that there is no damage. If there is packaging damage or signs of cable damage, it should be recorded in time and communicated with the transporter and shipper for handling.

(III) Delivery

The delivery process of YJV and YJY aluminum core cables focuses on efficiency and accuracy to ensure that customers can receive products that meet the requirements on time.

After the customer places an order, the sales department promptly enters the order information into the system and transmits it to the warehouse and production department. After receiving the order, the warehouse immediately checks the inventory. If it is an in - stock product, after confirming that the specification, quantity and other information are consistent with the order, it arranges for goods preparation; if it is a customized product, the production department organizes production according to the order requirements and notifies the warehouse for storage after production is completed.

During the goods preparation process, warehouse personnel conduct strict inspections on the cables, including whether the appearance is intact, whether the label information is accurate, and whether the packaging meets the standards. At the same time, sort out relevant product materials, such as product certificates, test reports, and user manuals, and prepare them for delivery together with the cables.

Before delivery, the warehouse contacts the transportation company, determines the transportation method and transport vehicle according to the order situation, and signs a transportation agreement with the transportation company, specifying the transportation time, transportation route, cargo storage responsibility and other matters. For urgent orders, priority is given to arranging delivery, and transportation resources are coordinated to ensure shipment within the agreed time.

After the goods are shipped, the warehouse promptly feeds back the logistics information (such as the name of the transportation company, waybill number, contact information, etc.) to the customer, facilitating the customer to track the transportation status of the goods. At the same time, the warehouse retains delivery records, including delivery orders and logistics documents, for future reference.

If problems such as delayed goods and damage occur during transportation, the warehouse will promptly communicate and coordinate with the transportation company and inform the customer of the progress of the handling.
