The BCC (Bare Copper Conductor) manufactured by Zhongdong Cable is used for electrical grounding, overhead power distribution, railway electrification, and industrial power applications where high electrical conductivity and reliable current carrying performance are required.
BCC is made of hard-drawn copper wires stranded concentrically to provide excellent conductivity, good mechanical strength, and long-term outdoor performance. Compared with aluminium conductors, copper conductors offer higher conductivity and better resistance to oxidation, making them suitable for applications requiring efficient power transmission and grounding reliability.

BCC provides higher electrical conductivity and better grounding performance, making it suitable for applications where low resistance and reliable current flow are required.
BCC is made of copper and offers higher conductivity, while AAC is made of aluminium and provides a lighter and more economical solution for overhead distribution lines.
It is widely used for grounding systems, substations, railway electrification, lightning protection, and industrial electrical connections.
Yes, but due to the higher material cost and weight, copper conductors are usually selected for specific applications requiring maximum conductivity rather than general long-span transmission lines.
BCC can be supplied in various cross-sections and strand configurations according to project requirements and applicable standards.
