XRUHKXS Cable

XRUHKXS Cable Construction

XRUHKXS Cable Application

• Medium-voltage power distribution networks: Used for power transmission and distribution at the 6/10 kV, 12/20 kV, and 18/30 kV voltage levels.
• Wind Farms: In cable runs between offshore wind turbine arrays, as well as in tower cables and collection systems for onshore wind farms, its water-barrier structure effectively prevents moisture penetration.
• Substation Connections: Used for medium-voltage connections between wind farm collection points and step-up transformers.

XRUHKXS Cable Standard

• IEC 60502-2, Generally to PN HD 620 10R

XRUHKXS Cable Feature

• Insulation Properties: XLPE (cross-linked polyethylene) insulation; the conductor’s maximum continuous operating temperature is +90°C.
• Short-Circuit Resistance: During a short circuit (lasting up to 5 seconds), the conductor’s maximum temperature can reach +250°C.
• Metal Shielding: Consists of copper wires and a copper tape, providing a fault current path and electromagnetic shielding.
• Minimum Bending Radius: Typically 15 times the cable’s outer diameter, offering good flexibility during installation.
• Installation Temperature: Installation is permitted at temperatures as low as -20°C.
