High Voltage Power Cable

As a professional high quality High Voltage Power Cable manufacturer, Ceho will offer you the best after-sale service. The power cables (HV cables) usually refer to power cables with a rated voltage of 66 kV and above. High-voltage power cables are used for large-capacity and long-distance power transmission and are key equipment connecting power plants, substations and the main urban power grid.

Ceho is a manufacturer and supplier specializing in supplying High Voltage Power Cable. As a professional supplier of cables, we are responsible for providing various high-voltage cables, including British standards, American standards, European standards, etc. Of course, we can also customize the type of underground high-voltage cables according to your needs.


You can consult us about cable solutions via email to facilitate our design and use around the specific requirements of your application and project.


We are good at challenging cables of different quantities or lengths, or structures that are technically difficult. The typical structure of high-voltage cables consists of core wires, inner insulation layers, semiconductor layers, steel armor, filling materials and outer insulation layers. Cables for different purposes use different materials, but the core wires are all copper or aluminum cores. Aluminum is the most widely used material at present. Copper is relatively expensive and is only used in cables of 35kV and above.
