TACSR-Thermal-Resistant Aluminum Alloy Conductor Steel Reinforced

Thermal-resistant Aluminum Alloy Conductors Steel Reinforced used in the

35KV 110KV 220KV 330KV 500KV 750KV 1000KV substation project

High Temperature Thermal Resistant Alloy Conductor

Application

Thermal-Resistant Aluminum alloy conductor,steel core reinforced is used for overhead transmission line, ground line, electric railway. Due to its obvious advantage of anti-corrosion and high strength, it is applicable for long- span line, severe cold zone with heavy snow and other bad weather besides general transmission line.Used for power plant, power transmission and distribution line, the voltage ranges from 1 kV to 750 kV, especially used in compacity – expansion route and transformation of the old lines.

Thermal-Resistant Aluminum alloy conductor ,steel reinforced is a high ampacity conductor with inner core composed of Steel wire & outer layer composed of thermal resistant aluminium alloy with round.
