Product Introduction

Introduction to 0.6/1kV Low-Voltage Power Cable Products and General Information

I. Product - Related Information

(I) Specification Parameters

In terms of conductor cross - section specifications, there are mainly two types: 3×120 + 70mm² and 3×150 + 70mm². The 3×120 + 70mm² is composed of 3 main cores of 120mm² and 1 neutral core of 70mm². The 3×150 + 70mm² consists of 3 main cores of 150mm² and 1 neutral core of 70mm². This structural design is not accidental. The main cores are responsible for the main power transmission task, and the size of the cross - section directly affects the current - carrying capacity of the cable. The 120mm² and 150mm² main cores can meet the power transmission scenarios with different power requirements respectively. The 70mm² neutral core plays a role in balancing the current when the three phases are unbalanced, ensuring the stable operation of the power system.

These cables have a rated voltage of 0.6/1kV, which determines that they are mainly used in the field of low - voltage power transmission. 0.6kV is the phase voltage of the cable, and 1kV is the line voltage. It conforms to the common voltage standards of low - voltage power systems and can match most low - voltage electrical equipment and power distribution systems.

(II) Characteristic Uses

Due to their good performance and structural characteristics, these cables are widely used in many fields. In terms of building power distribution, both residential buildings and commercial buildings need stable and reliable power supply. These cables can transmit power from the distribution room to each floor and electrical unit, meeting the needs of various electrical equipment such as lighting, air conditioners, and elevators. Their underground laying feature also avoids the space occupation and potential safety hazards caused by open laying of cables inside the building.

Power transmission in industrial plants is also an important application scenario. A large amount of power is often needed in industrial production to drive various mechanical equipment. These cables can bear a certain load, ensure the stable transmission of power, and ensure the continuous progress of production. At the same time, the environment of industrial plants is relatively complex, and underground laying can reduce the impact of external factors such as mechanical collision and chemical corrosion on the cables.

In municipal underground power grid projects, these cables play a key role. They are like "blood vessels" underground, transmitting power to all parts of the city and providing power support for street lamps, traffic lights, municipal facilities, etc. Their ability to adapt to the underground environment can ensure the stable operation of the urban power grid and reduce problems such as power outages caused by cable faults.

(III) Material and Style

The material of the cable is one of the key factors determining its performance. Different types of cables use different materials. Taking the YJLV cable as an example, it uses an Aluminum Core as the conductor. Aluminum has good conductivity, and compared with copper, it has lower cost and lighter weight, which is advantageous in scenarios where cost and weight are required. Its insulation layer is made of cross - linked polyethylene material. Cross - linked polyethylene has excellent electrical performance, high insulation resistance, and low dielectric loss, which can effectively reduce energy loss during power transmission. At the same time, it also has good aging resistance and heat resistance, and can maintain stable performance for a long time.

Other models such as Ar2V and Na2xy may use polyvinyl chloride or polyethylene as insulation and sheath materials. Polyvinyl chloride has good mechanical properties and chemical corrosion resistance, and its price is relatively low, which is suitable for some ordinary underground laying environments. Polyethylene has better Flexibility and low - temperature resistance, and performs better in cold areas or scenarios that require bending and laying.

In terms of style, these cables all have a circular structure. This structure is convenient for the laying and installation of cables, and can reduce resistance when laying in underground pipelines or direct burial. At the same time, the circular structure also makes the force on the cable more uniform, improving the mechanical strength of the cable.

(IV) Production Process

The production of cables is a complex process that requires strict control through multiple processes. Firstly, the conductor is manufactured. Aluminum rods or other metal materials are drawn into wires with the required cross - section by a wire drawing machine, and then annealed to improve the flexibility and conductivity of the wires. For multi - Core Cables, multiple wires need to be twisted together to form main cores and neutral cores.

Next is the extrusion of the insulation layer. Taking the YJLV cable as an example, an extruder is used to uniformly coat the cross - linked polyethylene material on the outside of the conductor to form the insulation layer. During the extrusion process, parameters such as temperature and pressure need to be strictly controlled to ensure that the insulation layer has a uniform thickness, a smooth surface, and no defects such as bubbles and impurities.

Then comes the cabling process. The main cores and neutral cores are twisted together according to a certain structure, and some filling materials are filled in the middle to ensure the roundness of the cable. After that, a sheath layer is coated on the outside of the cabled core. The material of the sheath layer varies according to the type of cable, and it is also made by the extrusion process.

During the production process, a series of quality inspections are also required, such as conductor resistance test, insulation resistance test, and voltage withstand test, to ensure that the performance of the cable meets relevant standards and requirements. Only cables that pass the inspection can leave the factory for sale.

II. General Product Information

(I) Packaging

The packaging link is crucial to ensure that the cables are not damaged during transportation and storage. These cables are usually packaged with cable reels, and there are two types of cable reels: wooden and steel. Wooden cable reels have low cost and light weight, but their bearing capacity is relatively weak, and they are suitable for cables with shorter lengths. Steel cable reels have higher strength and bearing capacity, are suitable for cables with longer lengths, and can better protect the cables from being crushed and deformed during transportation.

When packaging, the cables will be neatly wound on the cable reels and wrapped with plastic film or linen to prevent the cables from being eroded by dust, moisture, etc. At the same time, information such as the model, specification, length, rated voltage, and production date of the cable will be marked on the cable reel to facilitate users' identification and acceptance.

(II) Transportation

There are many aspects to pay attention to in the transportation of cables. Firstly, during the loading process, collisions between cable reels should be avoided to prevent mechanical damage to the cables. Forklifts or cranes can be used for loading and unloading to ensure a smooth and safe loading and unloading process.

During transportation, the cable reels should be fixed firmly to prevent them from shaking or rolling during the driving of the transport vehicle. For long - distance transportation, weather factors also need to be considered. In case of rainy days, the cables should be covered to prevent rainwater from entering the interior of the cables. At the same time, the transport vehicle should drive smoothly, avoiding operations such as sudden braking and sharp turns to reduce the impact on the cables.

Transportation requirements may vary in different regions. Before transportation, it is necessary to understand the traffic rules and transportation restrictions of the destination to ensure that the transportation process is legal and compliant. For some large cable reels, it may be necessary to go through over - limit transportation procedures.

(III) Delivery

Adequate communication with customers is required in the delivery link. After receiving the order, the staff will prepare cables of the corresponding model, specification, and length according to the customer's needs and check them to ensure the accuracy of the goods. Then, appropriate transport vehicles and transportation time are arranged, and the customer is promptly informed of the delivery information, including the license plate number of the transport vehicle, the driver's contact information, and the estimated arrival time, to facilitate the customer to prepare for receipt.

If the customer has special delivery requirements, such as specifying a logistics company or urgent delivery, they should be met as much as possible. Before delivery, a final inspection of the cables is also required to ensure that the packaging is intact and the marks are clear.

(IV) Samples

It is necessary to provide sample services to allow customers to understand the quality and performance of the cables before bulk purchase. Customers can put forward sample requirements to the supplier, and the supplier will provide corresponding samples according to the model and specification specified by the customer. The length of the sample is generally 1 - 2 meters, which can meet the customer's inspection of the cable's appearance, material, and cross - section structure.

When providing samples, the samples will also be packaged and marked to ensure the integrity of the samples and the accuracy of the information. At the same time, relevant test reports and technical data of the cables can also be attached to help customers better understand the performance of the samples.

(V) After - sales Service

A sound after - sales guarantee is an important guarantee for customers to purchase products. If customers encounter problems during the installation and use of the cables, they can contact the after - sales service personnel of the supplier at any time. The after - sales service personnel will provide technical support and solutions in a timely manner according to the situation reflected by the customers.

If the cable has quality problems caused by non - human factors within the warranty period, the supplier will repair or replace it in accordance with relevant regulations. At the same time, the supplier can also provide cable installation guidance services, and send professional personnel to the site to guide customers in laying and connecting the cables to ensure the installation quality.

In addition, the supplier will also conduct regular return visits to customers to understand the use of the cables, collect customers' opinions and suggestions, and continuously improve product and service quality.
