medium voltage cable
Single core 6.35/11 (12) kV copper MV cable utilizes high-purity stranded and compacted copper conductors, providing lower conductor resistance and higher current carrying capacity in medium-voltage distribution systems. Compared to aluminum conductors, medium-voltage copper conductors at the 6.35/11 (12) kV level offer more stable electrical performance and superior short-circuit withstand capability, effectively reducing line losses and improving system operational reliability. The single-core structure, combined with a uniform shielding system, results in a more symmetrical electric field distribution, significantly reducing the risk of partial discharge, making it particularly suitable for medium-voltage networks requiring high operational safety and long-term stability.

Advantages of medium voltage cable
Medium voltage cable features a single-core design with a core conductor made of stranded and compacted circular copper conductors conforming to AS/NZS 1125, possessing excellent mechanical strength and conductivity. The single-core copper conductor is extruded with a semiconducting conductor shield, which, along with the XLPE insulation layer and a peelable semiconducting insulation shield, forms a stable and uniform medium-voltage insulation system. The metal shielding layer, composed of copper wires and copper tape, provides a reliable grounding path for the single-core medium-voltage cable, meeting the stringent requirements for fault current and electromagnetic shielding in 6.35/11 kV systems.

APPLICATIONS
Single core copper 6.35/11 (12) kV MV cable is widely used in main power supply circuits and ring network systems of 6.35/11 kV distribution networks. The single-core copper conductor structure makes it particularly suitable for substation outgoing lines, underground cable laying, and medium-voltage power connections in commercial and industrial projects, including urban power distribution, residential areas, industrial plants, and public infrastructure.
Commercial Complexes
Suitable for 11 kV main power supply lines in commercial buildings such as shopping malls, hospitals, airports, and data centers, the single-core copper conductor structure provides higher current carrying capacity in limited spaces, ensuring stable power supply to critical loads.
Industrial Plants
In 6.35/11 (12) kV distribution systems within industrial parks, single core copper medium voltage cable is used to connect main transformers, motor control centers, and large equipment. The copper conductor is particularly suitable for high-load and frequent start-stop industrial conditions.
Residential Areas
Single core 6.35/11 kV copper MV cable is commonly used in underground medium voltage main lines in residential areas, supplying power to multiple distribution transformers. The single core structure improves installation flexibility, and the copper conductor ensures long-term, low-maintenance operation.
Tunnel
6.35/11 (12) kV single core copper medium voltage cable is suitable for direct burial or conduit installation, providing stable medium-voltage power transmission in underground power projects, and is ideal for projects requiring high mechanical strength and electrical performance.
