Product Overview
The MV-90/105 XLPE Insulation Type Cable is a high-performance medium-voltage power cable designed for industrial, commercial, and utility applications. Rated for 5kV to 46kV systems, it features thermoset cross-linked polyethylene (XLPE/TR-XLPE) insulation, copper wire shielding, and optional water-blocking technology. Compliant with UL 1072, ICEA S-94-649, and AEIC CS8 standards, this cable ensures reliable power transmission in wet/dry environments, underground ducts, or direct burial installations, even under extreme thermal conditions (up to 250°C short-circuit rating).
Key Features
-
High Thermal Capacity: Continuous operation at 105°C (emergency 140°C, short-circuit 250°C).
-
Robust Shielding: Copper wire or tape shield for EMI protection and fault current management.
-
Water Resistance: Optional strand-filled or dual-sealed design passes ICEA-T-31-610/664 water penetration tests (15 psi for 60 mins).
-
Flexible Construction: Available with copper (ASTM B496) or aluminum (ASTM B400) conductors.
-
Durable Jacketing: Black sunlight-resistant LLDPE or PVC outer sheath with red identification stripes.
