Description
Description
Application:
In low voltage power distribution networks. Special application in places with poor ventilation, direct application in places with public attendance high. It can be installed in ducts or directly underground in dry and wet places.
Construction:
1. Conductor: Aluminium 1350, class D.
2. Insulation: Halogen free, anti-flame cross linked polyethylene XLPE.
3. Outer sheath: thermoplastic compound HFFR-UV.
Main characteristics:
The cable has excellent electric properties. The cross-linked polyethylene insulation allows a higher power capacity current under any operation conditions, lower dielectric losses, high insulation resistance. The outer sheath has the following characteristics: Fire retardant, low emission dense smoke and halogen free. Adequate resistance to oils. Resistance to sunlight.
