This cable is a specialized covered conductor for medium-voltage overhead power distribution. The 3-Layer 35kV AAAC Tree Wire Spacer Cable has a multi-layered protective covering that prevents direct shorts and flashovers caused by external objects like tree limbs. This makes it an excellent choice for areas with limited space or where power lines pass through wooded regions.
Key Specifications & Construction
- Voltage: 35 kV phase-to-phase.
- Conductor: Concentrically stranded All Aluminum Alloy Conductor (AAAC), made from 6201-T81 aluminum alloy. This provides high strength and excellent conductivity.
- Layers: The '3-layer' design typically includes a semi-conducting layer, the primary insulation, and a final protective outer layer.
- Insulation: The primary insulating layer is cross-linked polyethylene (XLPE).
- Sheath: The outermost layer is a high-density track-resistant polyethylene (HDPE).
- Standards: The cable complies with key industry standards, including ICEA S-121-733, ASTM B231, ASTM B399, and ASTM B232.
Technical Data
- Normal Operating Temperature: 90°C.
- Emergency Overload Temperature: 130°C.
- Short Circuit Temperature: 250°C.
- AC Testing Voltage: The cable is tested at a voltage suitable for a 35 kV rating.
