HTLS Conductor Products --- STACIR/AW Conductor is a new type of overhead conductor
STACIR/AW conductor is a new type of overhead conductor. The use of trapezoidal wire increases the cross-sectional area of the conductor, so that the conductor has the effect of increasing the conductive capacity.
Under the same size, STACIR/AW conductors have better current carrying capacity than traditional conductors. At the same time, INVAR conductor is composed of aluminumclad invar core and thermal-resistant aluminum alloy wires. This conductor is suitable for old line
modification. It can keep the same sag while increasing capacity.
The main aspect of this type of conductor is the possibility of sliding between the outer layer and the core. Steel and aluminum are independent, so at high temperatures, the outer layer may stay on the steel core.
The outer conductive layer is made of super heat-resistant Al-Zr alloy, and the working temperature can reach 210°C.
The main features of this product series are:
INVAR core and outer layer independently have knee points at installation temperature
Limit the sag as the temperature increases
The thermal expansion coefficient above the knee point related to the INVAR core maintains the mechanical strength of the conductor, and the continuous working temperature is up to 210° C
This technique requires a skilled installation expert stage.
It is suitable for ACSR replacement on flat land or with small level differences.

Super Thermal Alloy Conductor: The conductor is made of a super thermal alloy material. This material is specifically engineered to have high thermal conductivity, allowing for efficient heat dissipation during power transmission.
Invar Reinforced: The conductor is reinforced with Invar, which is a nickel-iron alloy known for its low coefficient of thermal expansion. Invar helps to minimize conductor sag or elongation due to temperature changes, ensuring the stability and reliability of the power transmission line.
