The 3-Layer 35kV AAC Tree Wire Spacer Cable is a covered conductor for medium-voltage overhead power distribution. The '3-layer' design provides multiple layers of protection against faults caused by contact with external objects like tree limbs. It's an ideal choice for areas with limited space or where lines pass through wooded regions. There's a discrepancy in the provided technical data, where the voltage is listed as 15kV, but the product is titled 35kV. The information below assumes the 35kV title is correct.
Key Specifications & Construction
- Voltage: 35kV phase-to-phase
- Conductor: Concentrically stranded All Aluminum Conductor (AAC), made from 1350-H19 aluminum.
- Layers: The 3-layer design includes a semi-conducting layer, 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 ICEA S-121-733, ASTM B231, ASTM B399, and ASTM B232.
Technical Data
- Normal Operating Temperature: C
- Emergency Overload Temperature: C
- Short Circuit Temperature: C
- AC Testing Voltage: The cable is tested at a voltage appropriate for a 35kV rating.
