Non-insulated wire with steel core designed for transmission lines

APPLICATION:

Ashore power transmission within power networks in any macroclimatic areas of moderate and cold climate.

CONSTRUCTION:

Conductor - Stranded conductor twisted of aluminum wires Core - Made of solid or twisted steel galvanized wires

OPERATION AND INSTALLATION CONDITIONS:

The wire shall have overhead installation on TLs supports in accordance with Electrical and technical regulations on power plants and networks located in air atmosphere of 1 and 2 types, provided that sulfur dioxide content in atmosphere does not exceed 150mg/m2*day (1.5 mg/m3).

Operating temperature - From -60° C to 40°C

Max allowable continuous temperature of conductor heating during operation - 90°C.

Minimum service life under normal operating conditions - at least 45 years

ELECTRICAL CHARACTERISTICS:

Conductor resistance calculated per 100 m of cable length and temperature of 20°C does not exceed 9.6 Ohm. Resistance difference of conductors in working pair per 100 m length does not exceed 3%.
