Aerial Bundled Cable
1. Application
This product is suitable for overhead power lines with AC rated voltage of 1kV and below.
2. Cable Performance
The long-term allowable operating temperature of the cable shall not exceed 90℃.
Cable bending radius: it shall not be less than 12 times the outer diameter of the cable.
The cable laying temperature shall not be less than-20℃.
3.1 The conductor
Conductor shall be stranded conductor except for test line, which is solid conductor. The single line of the hanging line shall be aluminum magnesium silicon alloy wire. The conductor of the wire shall be composed of a single aluminum 1 pure NFC31-122 Al 1350.
3.2 Insulation
The insulation should be black extrusion crosslinking faintly, for neutral cable, the conductor should be wrapped around the paper strip isolation layer.
