This cable is a specialized covered conductor for primary and secondary overhead distribution. It's designed for situations where space is limited, such as in congested areas or corridors. The cable's covering provides protection against direct shorts and flashovers with other objects, although it is not a fully insulated cable. The term '2-Layer' refers to the distinct layers of insulation and sheath.
Key Specifications & Construction
- Voltage: 15 kV phase-to-phase
- Conductor: Concentrically stranded 6201-T81 aluminum alloy (AAAC). Other options like AAC or ACSR are also available.
- Insulation: Cross-linked polyethylene (XLPE).
- Sheath: A protective outer layer of high-density track-resistant polyethylene (HDPE).
- Standards: The cable meets several 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 outages caused by momentary contact with tree limbs or other objects. Its compact design and durable covering minimize the required space and hardware for installation, making it a reliable solution for:
- Lines running through wooded areas 🌳
- Congested urban alleyways
- Rights-of-way where limited space is a concern
