AVT, AVTV, AVTVU

Insulated wires for overhead lines. Wires AVT, AVTV and AVTVU with steel cable messenger. TU16.K71-015-87. These wires are designed for transmission and distribution of electrical energy in power and lighting networks with AC voltage up to 380 kV at 50 Hz.

AVT is a wire made of solid aluminium conductors in PVC insulation with a cable messenger made of 7 galvanized steel wires. It is designed to be laid outdoors for in-feeding to residential and other buildings in I and II icing degree regions.

AVTV is a lightweight wire made of solid aluminium conductors in PVC insulation with a cable messenger made of 7 galvanized steel wires. It is designed for indoor use.

AVTVU is a wire made of solid aluminium conductors in PVC insulation with a reinforced cable messenger made of 19 galvanized steel wires. It is designed for indoor use when higher mechanical strength is required.
