Product Description

Product Description

 

1. General Overview
   This power cable is a high - performance cable specially designed for power transmission. It combines a copper conductor, a polyvinyl chloride insulation layer, a polyethylene sheath and an armoured structure, and is applicable to various power transmission scenarios and can operate reliably in complex environments.
2. Copper Conductor

 

• Material Characteristics: Copper, as a conductor, has excellent electrical conductivity. Its high conductivity can effectively reduce the loss during power transmission and ensure efficient power transmission. Meanwhile, copper has good flexibility, facilitating the manufacturing and laying of the cable and enabling it to adapt to different bending radius requirements.
• Application Advantages: In the power system, a high - quality copper conductor helps to reduce the line resistance, decrease the heat generation and increase the current - carrying capacity of the cable. This means that a larger current can be transmitted without sacrificing safety to meet the requirements of different - scale power loads.

 

1. Polyvinyl Chloride Insulation

 

• Insulation Performance: Polyvinyl chloride (PVC) is a widely - used insulating material. It has good electrical insulation properties, which can effectively prevent current leakage and ensure that electric energy is transmitted along the conductor. Its high insulation resistance enables it to withstand a certain voltage without breakdown, providing a basic guarantee for the safe operation of the cable.
• Other Characteristics: The PVC insulation layer also has a certain degree of chemical corrosion resistance and can resist the erosion of chemical substances that may be encountered in different environments, such as acid and alkali substances commonly found in industrial environments. In addition, it has a certain degree of wear resistance, which can reduce the damage to the insulation layer caused by mechanical actions such as friction during cable laying and use.

 

1. Polyethylene Sheath

 

• Protective Function: The polyethylene (PE) sheath provides additional protection for the cable. It has excellent moisture - proof performance and can effectively prevent water from entering the cable interior, because water may damage the insulation performance of the insulation layer and cause cable failure. At the same time, the PE sheath provides physical protection for the insulation layer and conductor inside the cable, preventing mechanical damage from the outside, for example, being scratched by hard objects such as stones during underground laying.
• Environmental Adaptability: The polyethylene sheath also has good weather resistance and can be used for a long time under different climatic conditions. Environmental factors such as high temperature, low temperature or ultraviolet radiation will not easily cause it to age or be damaged, thus prolonging the service life of the cable.

 

1. Armoured Structure

 

• Protective Function: The armoured layer is an important part of this cable, which can significantly enhance the mechanical strength of the cable. When the cable may be subjected to external forces such as compression, tension or impact, such as when in contact with other objects in underground pipes or when laid near construction areas, the armoured layer can protect the conductor and insulation structure inside the cable from damage and ensure the continuity of power transmission.
• Material and Design: The armouring materials usually adopt high - strength metal materials such as steel tapes or steel wires. Its design structure is reasonable, can evenly bear external forces, and is closely combined with other parts of the cable without affecting the flexibility and layability of the cable.

 

1. Application Scenarios

 

• Industrial Field: It is suitable for power supply of power equipment in factories, such as motors, production lines, etc. In the industrial environment, there are various complex factors such as chemical substances, mechanical vibration and electromagnetic interference. The protection performance and stable power transmission ability of this cable can meet the requirements of industrial production.
• Building Field: It can be used in the power distribution system in buildings, including power supply lines for lighting, sockets, etc. During the construction and use of buildings, the cable may be subjected to certain external forces. The armoured structure can ensure the safety of the cable. At the same time, its good insulation and sheath performance are also suitable for use in the building environment.
• Outdoor Power Transmission: For outdoor power transmission and distribution lines, especially when laid underground or need to cross complex terrains, the moisture - proof, mechanical - damage - proof and armoured protection capabilities of this cable make it an ideal choice. It can work stably under different climatic and geological conditions and ensure that power is transmitted from substations to various power - consuming areas.
• Other Fields: It can also be applied in mines, ports and other places with high requirements for cable protection performance to provide reliable power supply for various electrical equipment.

  Product Parameters

• Flame - retardant performance
  According to the application scenario of the cable, there may be different flame - retardant grades, such as ordinary flame - retardant, high - flame - retardant, etc. It is measured by relevant flame - retardant test standards. For example, under the specified fire source conditions, the self - extinguishing time, burning length and other indicators of the cable meet the requirements of the corresponding grade to ensure safety in emergency situations such as fire.
• Bending radius
  During the cable laying and installation process, the minimum radius at which the cable can be bent, usually expressed as a multiple of the cable diameter, such as 6 times, 10 times the cable diameter, etc. If the bending radius is too small, it may damage the internal structure of the cable and affect the cable performance.
