P-274 Wire Structure

  • electric conductor consist of 3 tinned steel wires with diameter of 0.3mm in accordance with TU 14-4-1457 and 4 copper wires in accordance with TU 3518 PK 4043838373;
  • light-stabilized PE insulation in accordance with TU 6-11-00203335-97-95;
  • wire insulation color - black;
  • two electric conductors twisted in a pair.

P-274PP Wire Structure

  • the same as P-274, with two-layer insulation of wires. Inner layer of insulation is made of high-density PE. External layer of insulation is made of light-stabilized LDPE.

P-274, P-274PP Wire Application

The wires are used for permanent and temporary connecting with a laying in soil, on the ground, hanged on poles as well as for short-term laying through water.
