Technical Parameters

Hebei Hualun Cable Co., Ltd. is one of the most reliable manufacturers and suppliers of single core power cable in China. If you're going to wholesale durable single core power cable made in China, welcome to get quotation from our factory. All customized products are with high quality and competitive price.

Single Core Power Cable has a plain annealed copper or aluminium conductor complying with IEC 60228 class 1 or 2. It is designed for distribution of electrical power with nominal voltage 1.8/3KV to 26/35KV and frequency 50Hz. It is suitable for installation mostly in power supply stations, indoors and in cable ducts, outdoors, underground and in water, as well as on cable trays for industries, switchboards and power stations. Insulation is PVC for 1.8/3KV and 3.6/6KV cables, XLPE or EPR/HEPR also available.

Product Q&A

Q: What effect does the armour have when Single Core Power Cable is used in an AC system?

A: When single core cables are used in an AC system, the aluminium wire armour or metallic screen will generate induced currents, causing additional losses. Non-magnetic armour should be used, or an earthing method other than two-end earthing should be adopted for the armour, as determined by the system earthing design.

Q: How are the conductor screen and insulation screen treated at joints?

A: At joints, the conductor screen and insulation screen should be stripped back according to the accessory manufacturer's instructions. After stripping, the screen should be restored with a compatible semi-conducting material before applying the joint insulation. The stripping length and step dimensions shall follow the joint process requirements to avoid electric field concentration.

Q: What are the fixing requirements when this cable is installed on cable trays or in vertical shafts?

A: For vertical installation, cable cleats should be installed at the designed spacing. Non-magnetic material cleats should be used to avoid forming a closed magnetic circuit. For horizontal tray installation, single core cables should be arranged in a triangular formation or spaced apart as designed, to reduce induced currents and heat dissipation effects.
