Application
The product is a new type of aerial cable for power transmission. It is extensively used in overhead power transmission line. It improves the safety and reliance of electrified wire netting.
Standard:
IEC 60228: Conductors of insulated cables.
ASTM A 475: Zinc coated steel wire strand.
NTP-IEC 60228: Conductors of insulated cables.
NTP 370.254: Cables for overhead distribution networks self-supporting XLPE insulated of rated voltages up to and including 0.6/1 kV.
Working conditions of aerial insulation power cable
1) Rated voltage: 0.6-1kV
2) The tallest work temperature of the cable conductor：XLPE insulation cable：90oC;
3) During having a short (lasting less than 5 seconds), the maximum temperature: XLPE insulated cables is 250oC;
4) During the cable lying, the ambient temperature must be above -20oC.
5) Bending radius allowance of the cable:
It should be no less than 4D for the cable with outer diameter less than 25mm;
It should be no less than 6D for the cable with outer diameter of 25mm or more.
Construction:
1. Conductor: Aluminium 1350, class 2.
2. Insulation: Cross linked polyethylene XLPE.
3. Public lighting: Aluminium 1350 insulated with cross-linked polyethylene XLPE.
4. Messenger: Galvanized stranded steel wire insulated with cross-linked polyethylene XLPE.
