Medium / High Voltage Power Cables
Medium-voltage (MV) and high-voltage (HV) XLPE cables are designed for power transmission and distribution systems. Cross-linked polyethylene (XLPE) insulated and polyvinyl chloride (PVC) sheathed, these cables feature excellent electrical and insulation performance, low failure rates, and the benefits of lightweight construction, ease of installation, and simple termination, making them a reliable and widely adopted solution for modern power transmission and distribution networks.
Key Features
Resistance to Thermal Deformation
PE cables soften and deform when temperatures rise to 100°C due to system overloads or short circuits, resulting in insulation failure.
In contrast, XLPE cables can withstand temperatures of up to 130°C during system faults without significantly affecting their service life. In short-circuit scenarios, they can tolerate temperature rises up to 250°C for 5-second intervals.

Low Smoke Free Halogen (LSFH) Materials
In addition to PVC and PE, low smoke free halogen (LSFH) materials are available for cable jacketing. LSFH materials feature low-smoke emission, non-toxic properties, and flame retardancy, significantly enhancing the safety and fire prevention performance of the cables.
