Product Description

Self supporting insulated wires (Aerial Bundled Conductor) SIP per GOST R 52373-2005 and TU 16-705.500-2006
(TU 16-705.500-2006 used instead of TU 16.К71-268-98 and TU 16.К71- 272-98)

Self-supporting Wire Description

SIP is a self-supporting insulated wire which is intended to transfer electrical energy in overhead power lines and branch off from trunk lines to enter into residential buildings and utility buildings. The laying is carried out on supports, as well as on the walls and structural elements of industrial and residential buildings.
AsXS is a self-supporting wire for overhead power lines with aluminum conductors, insulated with XLPE, resistant to ultraviolet.
AsXSn is a self-supporting wire with aluminum conductors, insulated with XLPE, resistant to ultraviolet, flame retardant.
The wires are designed for the transmission and distribution of electrical energy in power and lighting networks for an alternating voltage 0.6/1 kV.
The insulated wires with a neutral self-supporting conductor (SIP-1 and SIP-2) are intended for installation and reconstruction of overhead power transmission lines and linear branches from overhead lines, as well as descents to power electrical equipment.
The insulated wires without a neutral self-supporting conductor (SIP-4, SIP-5 and AsXS, AsXSn) are intended for the branches from overhead power lines to the enter, and for the laying along the walls of buildings and structures.
