This is a medium-voltage (MV) Aerial Bundled Cable (ABC) designed for overhead power distribution, built to the AS/NZS 3599.1 standard. The cable features a screened design for higher voltage applications, with three insulated cores bundled around a galvanized steel support wire. The construction is denoted by its materials: AL (aluminum conductor), XLPE (insulation), CWS (copper wire screen), and HDPE (sheath).
Key Specifications & Construction
- Voltage: 6.35/11kV
- Conductor: Compacted stranded hard-drawn aluminum (Class 2).
- Conductor Screen: An extruded semi-conductive layer.
- Insulation: Natural cross-linked polyethylene (XLPE).
- Insulation Screen: An extruded semi-conductive layer.
- Metallic Screen: Copper wire screen.
- Sheath: High-density polyethylene (HDPE).
- Support Conductor: Galvanized steel wires.
- Assembly: Three XLPE-insulated and screened cores are bundled in a right-hand lay around the galvanized steel support conductor.
Applications and Technical Data
This cable is used for medium-voltage overhead distribution in applications like street lighting, outdoor lighting, and temporary construction services. It is suitable for a maximum conductor temperature of C.
- Normal Operating Temperature: C
- Emergency Overload Temperature: C
- Short Circuit Temperature: C
