This is a specialized covered conductor for medium-voltage overhead power distribution. The 3-Layer 25kV ACSR Tree Wire Spacer Cable has a multi-layered protective covering that prevents direct shorts and flashovers from contact with trees or other objects. It's an ideal choice for areas where space is limited or where lines pass through wooded regions.
Key Specifications & Construction
- Voltage: 25 kV phase-to-phase.
- Conductor: Concentrically stranded Aluminum Conductor Steel-Reinforced (ACSR), providing a combination of high strength and good conductivity. Other conductor types like AAC or AAAC are also available.
- Layers: The 3-layer design consists of 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.
