11KV Copper Cable

This 11kV copper cable is designed for medium-voltage power distribution where stable electrical performance, insulation protection and mechanical durability all need to be considered together.
The cable uses a Class 2 copper conductor with XLPE insulation. The insulation system includes conductor shielding and insulation shielding, followed by a copper tape metal shield. A galvanized steel wire armor provides additional mechanical protection, while the outer sheath is made from UV-resistant, flame-retardant LSZH material.
The construction can be adjusted according to the project specification. The technical data shown on this page uses 3×240 mm² as an example and does not represent the only available size.
For projects with different voltage levels, conductor cross-sections, installation conditions or environmental requirements, Huayu's technical team can confirm the appropriate construction before production.

The XLPE insulation system is designed for medium-voltage operation and provides the electrical insulation required between the conductor and the surrounding layers.

The copper tape shield forms part of the cable's electrical shielding system. It also provides a defined metallic layer around the insulated cores, which is important when the cable is used in a medium-voltage distribution system.

Galvanized steel wire armor adds mechanical protection to the cable. This is useful where the cable may be exposed to pulling forces, impact or other physical stress during installation and operation.

The LSZH outer sheath is UV-resistant and flame-retardant. This makes the cable suitable for installations where low-smoke, halogen-restricted materials are specified, particularly in locations where fire safety and personnel protection are important considerations.

This cable is mainly used in medium-voltage power distribution and industrial electrical systems.

For industrial plants, it can be used for power distribution between substations, switchgear and major electrical equipment. The armored construction helps protect the cable where the installation route is exposed to mechanical stress.

For outdoor installations, the UV-resistant sheath is useful where the cable is exposed to sunlight for extended periods. The cable construction can also be considered for industrial sites with demanding environmental conditions, subject to the actual project requirements.

For facilities with stricter smoke and halogen requirements, the LSZH sheath provides an alternative to conventional PVC sheath materials. This can be relevant in enclosed or populated areas where smoke and corrosive gases during a fire are major concerns.

The cable can also be specified for projects where several requirements need to be considered at the same time - medium-voltage performance, mechanical protection, flame retardancy and outdoor exposure. Instead of selecting each feature separately, the complete cable construction is reviewed against the actual installation conditions.

Huayu Cable has been manufacturing wire and cable products since 2004. The company operates a production base of more than 258,000 m² and has developed 38 main product series with more than 8,000 specifications.

 

For medium-voltage cable projects, the benefit is not simply having different cable sizes available. A project may involve several cable types, different installation conditions and different certification requirements at the same time. Huayu's production, technical and sales teams can work together from the quotation stage to confirm the construction before the order enters production.

 

Huayu also maintains certification and testing capabilities covering a range of international and industry requirements, including ABS, CCS, DNV, LR, EAC/GOST, IEC, TÜV and CE, depending on the product and project specification.
