12/20kV CU/XLPE/PVC(or PE) Power Cable
1. Description
Construction: Compacted stranded circular copper conductor, extruded semi-conducting compound as conductor shield, cross-linked polyethylene (XLPE) insulation, semi-conducting compound as insulation shield, copper tape or combination of copper wire and tape as metallic screen, three cores assembled together with non-hygroscopic polypropylene filler, wrapped with binder tape, PVC or PE outer sheath.
2. Operating Characteristics
Rated voltage U0/U(Um): 12/20(24)kV
U0 is the rated power frequency voltage between conductor and earth or metallic screen for which the cable is designed;
U is the rated power frequency voltage between conductors for which the cable is designed;
Um is the maximum value of the "highest system voltage" for which the equipment may be used.

For three core cable: Not less than 15 times of the diameter of cable
3. Application
The cable is used for fixed installations such as electric power distribution networks or industrial installations, which is laid indoors, outdoors, in tunnel or in cable trench, unable to bear external mechanical force.
Single core cable in magnetic duct is not permissible.
4. Manufacturing Standards
IEC 60502-2 and Chinese National Standard GB/T 12706-2008 We can produce above cables according to popular international standards such as ASTM, BS, DIN, NF &AS/NZ also.

PVC cable, also known as polyvinyl chloride cable, is a type of electrical cable that is insulated with PVC material. PVC is a thermoplastic material that offers excellent electrical insulation properties, making it suitable for various applications.
PVC cables are commonly used in residential, commercial, and industrial settings for power distribution, wiring, and communication purposes. They are available in different sizes and configurations to meet specific requirements.
One of the main advantages of PVC cables is their affordability. PVC is a cost-effective material, making PVC cables a budget-friendly option for electrical installations. Additionally, PVC cables are lightweight and flexible, which makes them easy to handle and install.
PVC cables also have good resistance to moisture, chemicals, and abrasion, making them suitable for both indoor and outdoor applications. They have a wide operating temperature range and can withstand high voltage and current levels.
However, PVC cables have some limitations. They have relatively lower heat resistance compared to other cable types, which can be a concern in high-temperature environments. PVC is also less flame-resistant than some other materials, so additional fireproofing measures may be required in certain applications.
Overall, PVC cables are widely used due to their affordability, electrical insulation properties, and versatility. However, it is important to consider the specific requirements and environmental conditions of the application before choosing PVC cables.
