Self-supporting insulated wires SIP 4, SIP 5 (СІП 4, СІП 5)

SIP 4 - self supporting wire with current-conducting aluminum cores with insulation from thermoplastic polyethylene;

SIP 5 – to, that SIP 4 but with insulation from cross-linked polyethylene

 

SIP 4, SIP 5 - self supporting insulated wire (SIP) with nominal voltage from 660 kV and 1000 kV and frequency up to 50 Hz. SIP 4, SIP 5 are intended for electric energy transmission in air power network and branches to entering in dwelling, economic buildings in the air atmosphere of 2 and 3 types by GOST 15150. 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 – stranded, multiwire, sealed cores, from aluminum alloy with cross- sectional area 16 - to 240 mm². All cores have similar cross-sectional area. Without bearing element;
  2. 2. Insulation – light-stabilized thermoplastic polyethylene (for SIP 5 - light-stabilized cross-linked polyethylene). Insulation color is black.

 

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.
