HTLS Gap Conductor (GZTACSR/EST)

Gap-type Thermal-resistant Aluminum-alloy Conductor Extra-high-strength Steel Reinforced

Characteristics:
-Super thermal resistant aluminum alloy, double current carrying capacity at continuous working temperature 210℃.
-Extra high strength steel core, to support the whole tension of conductor and  stress on steel core only.
-Gap structure between aluminum layer and steel core. T shaped aluminum alloy wire to form the gap & tube structure. Gap filled with grease, steel core slip freely for the load transfer during stringing.
-High temperature low sag performance, upgrading the line capacity without replacing tower, saving space and land resources.
-Convenient installation.

Note: Current capacity is based on ambient temperature 40℃, Wind velocity 0.5m/s, Wind direction: 0 Degree, Solar radiation 0.1w/cm2, Absorptivity of conductor surface 0.9.

Transmission of high current carrying capacity, suitable for line upgrading without replacing tower. High temperature low sag performance, increase current capacity by 100%, yet no need to replace tower.
