СИП - 4 (ABC)

General information

Wire SIW-4 (ABC) is designed for overhead transmission lines with 0.66, 1.0, 10, 20, 35 kV, for input tapping of branch power lines, for in-air-laying on walls of buildings or engineering structures of types II and III according to GOST 15150. At a specified temperature of storage and operation wire materials do not give off pollutant emissions in concentrations dangerous for human body and polluting the environment.

STRUCTURAL DESIGN

  1. Conductor – aluminum, round, multi-wire stranded, compacted (GOST 22483 II class)
  2. Insulation

In SIW-4 wires, cross-linked polyethylene (XLPE) is used as an insulating material.
