HV Power Cable 110kV / 220kV High Voltage Cables IEC Standard High Voltage Cables

High voltage (HV) cable: The voltage range is usually between 35kV and 110kV, mainly used for medium and long distance power transmission, suitable for most municipal, factory and distribution networks.

Extra high voltage (EHV) cable: The voltage level is between 110kV and 220kV, widely used in urban power grids and cross-regional power transmission systems, ensuring low losses in long-distance transmission.

Ultra-high voltage (UHV) cable: The voltage level is 330kV and above, and can even reach 500kV, 750kV, 1000kV and higher. It is suitable for ultra-long distance and ultra-large capacity power transmission, usually used in national backbone power grids and large cross-regional power transmission projects.

Applications such as national power stations, power plants, nuclear power plants, cross-sea bridges, rail transit, petrochemicals, steel, military equipment, and military stabilizers.

High voltage resistance of insulation materials

High-voltage cables usually use materials with high insulation performance such as cross-linked polyethylene (XLPE), which can withstand high voltage stress, prevent corona discharge and cable breakdown, and ensure the safety of power transmission.

High-quality shielding layer design

Equipped with semi-conductive shielding layer and metal shielding layer, it can effectively control the electric field distribution, reduce electromagnetic interference, and ensure the stability of transmission and the electromagnetic compatibility of the surrounding environment of the cable.

High temperature resistance and strong corrosion resistance

The use of high-temperature resistant conductors and insulation materials is suitable for operation in high temperature or corrosive environments, and can maintain stable performance for a long time and extend the service life of the cable.

Large conductor cross-section

High-voltage cables usually use larger conductor cross-sections to reduce line resistance and loss, ensuring high-efficiency transmission during long-distance power transmission.

Stable structure and high mechanical strength

It has a multi-layer protection structure, including an outer sheath and metal armor, which can resist external mechanical stress and physical damage, and is suitable for installation requirements in underground or complex environments.

1. EN 50575

This standard applies to cables intended for fixed installations and specifies how the cables react to fire conditions, including combustion performance and smoke emission.

2.CPR (Construction Products Regulation)

EU regulations require that building products must meet certain safety, health and environmental protection requirements before they are put on the market. They are tested and classified according to their fire performance, such as A1, A2, B, C, D, E, F, etc. The higher the classification, the better the fire performance.
