ZTT high-voltage power cables have excellent electrical performance and are suitable for long-distance power transmission. They can be equipped with special properties such as flame retardancy, waterproofing, and termite resistance based on customer requirements.

Smooth Aluminum Sheath Cable: The smooth aluminum sheath can make closer contact with the buffer layer, significantly reducing its thermal resistance. It can carry larger short-circuit currents and has excellent conductivity, making cable operation more reliable.

Corrugated Aluminum Sheath Cable: The corrugated aluminum sheath can make closer contact with the buffer layer, greatly reducing its thermal resistance. It can carry larger fault short-circuit currents and has outstanding conductivity, making it more reliable for our customers.

Copper/Aluminum Wire + Aluminum-Plastic Composite Tape Armored Cable: This type of metal sheath is typically lighter in weight and can carry higher fault currents.
