  • Warranty lifetime for connecting moveable parts (railway rolling stocks) is not less than 8 years; for fixed mountings - not less than 15 years;
  • Factory length of the wire is not less than 100 m.

Wire Structure

  • Copper multi-wire lead cores of the 4th class in accordance with GOST 22483-77 (State Standard);
  • Insulation of lead cores made from thermoplastic elastomer (TPE);
  • Marking and coloring of lead cores in accordance with ТU U 31.3-13638750-021-2003 (Company Standard);
  • Insulated core of the wire is covered with belt insulation (tape PET-E);
  • Belt insulation is covered with a jacket of cold-resistant PVC elastron.

Applications

Power wire with copper lead cores for internal and external connections of railway rolling-stock, public electric and underground transportation vehicles. Proposed for connecting to moving current collectors, mounting in limited spaces and for assembling under lubricant oil and diesel fuel influence. The wire is designed for rated AC voltage 1000 V, frequency up to 400 Hz and DC voltage 1500 V.
