Insulated wires SIP 1, SIP 2 (СІП 1, СІП 2)

SIP 2 – self-supporting wire with aluminum current-conducting cores with insulation from cross-linked polyethylene with zero bearing core from aluminum alloy;

SIP 1 – to, that SIP 2, but with uninsulated zero core

 

SIP 1 and SIP 2 – self-supporting insulated wires with nominal voltage 0,66 kV and 1 kV and frequency up to 50 Hz . SIP 1, SIP 2 are intended for electric energy transmission in air power network and line branches from air lines in the atmosphere of 1 and 2 types (for SIP 1) and 2 and 3 types (for SIP 2) regulated by GOST 15150. SIP 1 and SIP 2 peculiarity - is zero messenger. Foreign equivalent of the wire can be found here.

 

Quality is regulated by:

DSTU 4743:2007, DSTU 4809:2007, TU U 31.3-30913256-001:2009.

 

Structure:

  1. 1. Current conducting cores – aluminum, of round form with cross-sectional area 16 mm² — single wire, multiwire sealed cores with cross-sectional area from 16 up to 120 mm²;
  2. 2. Retentive zero core — sealed, round core from aluminum alloy, stranded from round wires. In SIP 1 this core is uninsulated;
  3. 3. Insulation – light-stabilized cross-linked polyethylene. Color of insulation – black;
  4. 4. Strand — insulated current-conducting cores stranded around retentive bearing core.

 

Specifications:

  • operating temperature from -60 ºС up to +50 ºС;
  • maximum permissible reheat temperature of cores:
  • - at the short circuit (up to 4 seconds) - +250 ºС;
  • - during operation not more than +90 ºС;
  • installation and laying of cables without the preheating realizes with the temperature not lower than -20 ºС;
  • minimum bending radius by wire laying - 10 external dimensions of cable;
  • service life – not less than 40 years.
