YJHLV (TC90) Aluminum Alloy Power Cable is a high-performance medium-voltage power cable designed for a wide range of electrical distribution systems. Constructed with aluminum alloy conductors, XLPE insulation, and a durable PVC sheath, this cable is engineered to deliver reliable electrical performance in harsh environments such as underground installations, railway infrastructure, and industrial power networks.
The “TC90” designation indicates the cable's maximum continuous operating temperature of 90°C, making it suitable for demanding applications requiring thermal stability and mechanical robustness.
Key Features
-
Aluminum Alloy Conductor: Offers a lightweight, cost-effective alternative to copper with excellent conductivity and mechanical strength.
-
XLPE Insulation: Provides superior electrical insulation, thermal resistance, and aging performance.
-
PVC Outer Sheath: Flame-retardant and UV-resistant, protects against abrasion, moisture, and chemicals.
-
High Temperature Rating: Designed for continuous operation at 90°C, ensuring safety and reliability in heavy-load environments.
-
Corrosion Resistance: Aluminum forms a natural oxide barrier, ideal for underground or damp environments.
-
Cost-Efficiency: Lighter weight and lower material cost compared to copper cables, with minimal compromise on performance.
