- Product Details
20KV cables are designed for safe and stable operation at rated voltages of 12/20 kV (Um=24KV). 20KV XLPE insulated cables offer excellent electrical insulation, heat resistance and durability. Effective copper tape or copper wire shielding or guarantees system stability. These cables are used to supply power in medium voltage installation systems, they are suitable for installation indoors and outdoors, in cable ducts, underground, in power and switching stations, in local energy distribution, in industrial plants, without risk of mechanical damage. The different versions are tailored to the various installation environments, such as the 20kv N2XSY cable, which is flexible and can be buried directly.
