2-Layer 15kV ACSR Tree Wire Spacer Cable is a specialized covered conductor for medium-voltage overhead power distribution. The cable is designed for situations where space is limited and provides protection against flashovers and shorts, making it a safer option than bare conductors.
Key Specifications & Construction
- Voltage: 15 kV phase-to-phase
- Conductor: ACSR (Aluminum Conductor Steel-Reinforced), which provides a combination of high strength and good conductivity. Other conductor types like AAC and AAAC are also available.
- Insulation: The first layer is cross-linked polyethylene (XLPE).
- Sheath: The outer, protective layer is a high-density track-resistant polyethylene (HDPE).
- Standards: The cable adheres to several industry standards, including 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: 27 kV for 5 minutes
Application
Tree wire is primarily used in overhead distribution systems to prevent power outages caused by momentary contact with tree limbs or other objects. Its durable covering and compact design minimize the space and hardware needed for installation, making it ideal for:
- Lines passing through heavily wooded areas.
- Congested urban alleyways and corridors.
- Areas where rights-of-way are limited.
