INVAR

1. Ambient temperature 40℃, Wind velocity 0.5m/s, Wind direction: 0 Degree, Solar radiation 0.1w/cm2, Absorptivity of conductor surface 0.9.

2. Continuous operating temperature: TACIR 150℃, ZTACIR 210℃.

3. Other designs according to customers’ requirements.

ZTACIR is a Super(Z) Thermal Resistant Aluminum Alloy.

Invar steel ACSR conductor built with heat resistant Al Zr Aluminum alloy and a galvanized Invar steel core.

Aluminum Clad Invar steel is also used for higher temperature operation.

The conductors resemble an ACSR type of conductor.
