Wire A

Application

Non-insulated wire for overhead power lines.

  • Non-insulated wire A is designed to transmit electrical energy in overhead electrical networks.

ADVANTAGES

  • Wire production is carried out in strict accordance with GOST 839-80.
  • Minimum production time.
  • Own production of aluminum wire rod.
  • Drawing of aluminum wire on the modern high-speed complex TS45-13-1 (Mario Frigerio S.A. - Italy)
  • Wire twisting is performed on equipment with wire preformation, which provides tight twisting and eliminates the possibility of self-braiding of wires.
  • A large fleet of twisting equipment.
  • Receivers of the line are equipped with automatic distributors that provide uniform in-line layout of the wire on the drum.
