Overhead cables
Self-supported insulated overhead power transmission lines SAX and ABC
Tətbiqi sahəsi:Area of application: SAX and ABC type wires are laid for the purpose of lighting on the exterior of accomodations (external walls) or supplying technical equipment with power with rated operation voltage of up to 0.66, 1.0, 10, 20, 35 kV in accordance with II and III atmosphere specified in State Standard 15150. The insulation material used for the wire emits no toxic substance and concentrate hazardous for human organism and environment, when used in installation temperature.
The insulation material used in SAX type wires is low density thermoplastic polyethylene (LDPE)
The insulation material used in ABC type wires is cross-linked polyethylen (XLPE)
