Product Introduction

Detailed Introduction to the Single-Core PVC Insulated Copper Nyx Cable Series

I. Product - related Information

(1) Specification Parameters

The single - core PVC insulated copper Nyx cable series covers a variety of specifications, including 25mm², 50mm², 70mm², 95mm² and 300mm². These different specifications have different application scenarios in power transmission and can meet the diverse needs from low - voltage to medium - voltage scenarios.

In terms of core performance parameters, the conductor of this series of cables is made of electrolytic copper with a purity of more than 99.95%. This high - purity material ensures its low - resistance characteristic. Specifically, the DC resistance of the 25mm² conductor is ≤0.727Ω/km, and that of the 300mm² conductor is ≤0.062Ω/km. Compared with similar products, its current transmission loss is reduced by more than 15%, which means that energy can be used more efficiently in the process of power transmission, reducing unnecessary energy waste.

The PVC Insulation layer has excellent performance after being optimized with a special formula. Its temperature resistance range is - 15℃~70℃, which enables the cable to work normally in cold winters, hot summers and some environments with large temperature changes. The insulation resistance is ≥500MΩ·km, which can effectively prevent current leakage and ensure the safety and stability of power transmission. At the same time, the insulation layer also has the ability to resist moisture, mold and general chemical corrosion, which makes it especially suitable for environments such as underground direct burial or wall concealed laying.

The sheath and insulation layer of the Nyx model adopt an integrated design, which significantly improves the mechanical strength of the cable. Its tensile strength is ≥12MPa, and the elongation at break is ≥150%, which can withstand dragging and extrusion during construction, reduce damage to the cable caused by improper construction operations, and prolong the service life of the cable.

In terms of installation parameters, the bending radius of this series of cables is ≥10 times the outer diameter. Cables of 25mm² specification can be bent by hand, and the operation is relatively simple; while cables of 300mm² specification need to use special tools to complete bridge laying, because of their large specification, their own hardness and strength are relatively high, and manual bending is more difficult.

In terms of flame retardancy, the PVC material meets the GB/T 18380.3 - 2008 Class C standard, which can delay the spread of fire to a certain extent and reduce the fire risk. In addition, its halogen - free and low - smoke formula can reduce the release of toxic gases during combustion, striving for more time for personnel evacuation and rescue work and improving safety.

In addition, the entire series of cables have passed the GB/T 5023.3 - 2008 standard certification, and the 300mm² specification can also meet the needs of medium - voltage scenarios below 10kV, with both high - voltage tolerance and installation Flexibility. Each meter of the sheath is printed with clear marks, including specifications, voltage level and certification information. These marks not only facilitate identification during construction, but also provide convenience for later traceability.

(2) Characteristic Uses

The differentiation of specifications enables the single - core PVC insulated copper Nyx cable series to accurately adapt to different usage scenarios.

25mm² cables are mostly used in residential distribution branches and small motor power supply, such as central air conditioners and water pumps in families. In residential electricity use, the power of these equipment is relatively small, and 25mm² cables can meet their power transmission needs and ensure the normal operation of the equipment.

Cables of 50mm² and 70mm² specifications are suitable for commercial building main lines and medium - sized industrial machinery, such as lighting systems in shopping malls and injection molding machines. The electricity load of commercial buildings is relatively large, and the main lines need to have strong power transmission capacity, while the operation of medium - sized industrial machinery also needs stable power supply. These two specifications of cables can well meet these needs.

Cables of 95mm² and 300mm² specifications can be used for large - scale factory transformer connections and urban power grid branches, such as rolling mills in steel factories and outlet cabinets of substations. These scenarios have extremely high requirements for the capacity and stability of power transmission, and large - specification cables can meet their needs.

(3) Material and Style

The Conductor Material is electrolytic copper with a purity of more than 99.95%. This high - purity copper has excellent conductivity and is an ideal material for power transmission. The production process of electrolytic copper undergoes strict purification treatment to remove impurities, ensuring its conduction efficiency.

The insulation layer and sheath are made of PVC material, and the insulation layer is optimized with a special formula. PVC material has good insulation performance, chemical stability and mechanical strength, and can effectively protect the conductor. The optimization of the special formula further improves its performance such as temperature resistance, moisture resistance and corrosion resistance.

This cable series has a single - core structure, which has certain flexibility in the installation and use process. Single - Core Cables are relatively simple in structure and easier to lay in some limited space scenarios.

(4) Production Process

In terms of conductor production, advanced electrolytic refining technology is adopted to increase the purity of copper to more than 99.95%. This process removes impurities in copper through electrolysis to obtain high - purity electrolytic copper, laying the foundation for the low - resistance characteristic of the cable.

The insulation layer is made by a special formula mixing and extrusion molding process. First, PVC raw materials and various additives are mixed in a specific proportion to optimize performance. Then, the mixed materials are extruded and wrapped around the conductor through an extruder to form a uniform insulation layer. The extrusion molding process can ensure that the insulation layer has a uniform thickness and a smooth surface, ensuring the stability of its insulation performance.

The integrated design of the sheath and the insulation layer is realized through a special co - extrusion process. During production, the sheath material and the Insulation Material are extruded at the same time, so that they are closely combined to form a whole. This process not only improves the mechanical strength of the cable, but also enhances the bonding force between the sheath and the insulation layer, reducing the occurrence of delamination.

In the production process of the cable, there is also a strict quality inspection link. From the incoming inspection of raw materials, to the online inspection during production, and then to the outgoing inspection of finished products, each link is controlled by professional testing equipment and personnel. For example, the DC resistance of the conductor, the insulation resistance of the insulation layer, and the mechanical properties of the cable are tested to ensure that the product meets relevant standards and design requirements.

II. General Product Information

(1) Packaging

In order to ensure the quality of the cable during transportation and storage, the single - core PVC insulated copper Nyx cable series adopts a scientific and reasonable packaging method.

For cables of different specifications, the packaging methods are slightly different. Small - specification cables, such as 25mm², 50mm² and 70mm², are usually packaged in reels. The reels are made of high - strength wood or plastic materials, which can bear the weight of the cable and the pressure during transportation. The cable is neatly wound on the reel and wrapped with plastic film to prevent dust, moisture, etc. from polluting and damaging the cable. A fixing device is also installed on the side of the reel to fix the end of the cable to avoid loosening during transportation.

For large - specification cables such as 95mm² and 300mm², due to their large weight, they are usually packaged on wooden pallets. The cable is also neatly wound on the pallet and fixed with steel belts or ropes to ensure that it will not shift or fall during transportation. Anti - slip devices are installed at the bottom of the pallet to facilitate operation during transportation and loading and unloading.

Whether it is reel packaging or pallet packaging, clear marks are printed on the outside of the package, including product name, specification, length, weight, manufacturer, production date, certification mark and other information. These marks help users quickly identify and check products during receipt and storage.

In addition, for exported cable products, the packaging will be adjusted according to the relevant standards and requirements of the exporting country or region, such as using packaging materials and marks that meet international standards to ensure that the products can pass customs inspection and transportation smoothly.

(2) Transportation

The transportation of the single - core PVC insulated copper Nyx cable series needs to follow strict regulations and procedures to ensure the safety and integrity of the products.

In terms of transportation mode selection, according to factors such as the quantity, specification and transportation distance of products, various modes such as road transportation, railway transportation and waterway transportation can be adopted. For short - distance transportation and small batches of goods, road transportation is usually used, which has the characteristics of high flexibility and fast transportation speed. For long - distance transportation and large batches of goods, railway transportation and waterway transportation are more economical.

In the process of transportation, the following points need to be noted: First, the loading of cables should be firm to avoid collision, extrusion and friction during transportation. For reel - packaged cables, the stability of the reel should be maintained to avoid rolling. For pallet - packaged cables, they should be stacked reasonably to avoid excessive stacking leading to damage to the cables at the bottom. Secondly, during transportation, cables should be prevented from being exposed to direct sunlight, rain and snow, etc. Therefore, the transport vehicles need to be covered with tarpaulins to ensure that the cables are in a dry and ventilated environment. Thirdly, when loading and unloading cables, professional loading and unloading equipment, such as cranes and forklifts, should be used to avoid damage to cables caused by manual handling. During loading and unloading, handle with care, and it is strictly forbidden to throw or drag cables.

During transportation, special personnel should be assigned to be responsible for escorting. The escorts should be familiar with the characteristics of the cables and transportation requirements and can timely handle problems arising during transportation. At the same time, transportation records should be made, including transportation time, place, road conditions, cargo status and other information for later traceability.

For special weather conditions, such as rainstorms, heavy snow, high temperature, severe cold, etc., corresponding protective measures should be taken. In rainy and snowy weather, ensure that the tarpaulin of the transport vehicle is tight to prevent rainwater or snow from seeping into the package and damaging the cable. In high - temperature weather, avoid the cable being exposed to the sun for a long time to prevent the PVC material from deforming or aging due to high temperature. In severe cold weather, pay attention to the anti - freezing of the cable to avoid the insulation layer and sheath from becoming brittle and cracking due to low temperature.
