High Voltage HT XLPE cables are insulated cables that are designed to safely carry high-voltage electrical current over long distances. They are often used in transmission lines, substations and other electrical infrastructure.The most distinctive component of XLPE cables is the insulating layer, which is typically made of cross-linked polyethene (XLPE). This XLPE insulation is strong and resistant to wear and tear, making it ideal for long-term use. Apart from that, it is also resistant to most chemicals, allowing it to be used in applications where other materials would be prone to damage.
