Description :

STAIR/AW Aluminum Clad Invar Core Ultra Heat Resistant Aluminum Alloy Stranded Wire

　　Multiple Capacity Wire (STAIR/AW) - Aluminum Clad Invar Core Ultra Heat Resistant Aluminum Alloy Stranded Wire (JNRLH60/LBY14)

　　The material of ultra heat-resistant aluminum alloy wire is an alloy that adds various trace elements such as zirconium. By continuously casting a specific alloy system and using a specific heat treatment process, its heat resistance can be improved without reducing its conductivity, and its temperature can reach a short-term allowable temperature of 240 ℃.

　　Aluminum coated Invar wire is composed of a special alloy steel core twisted uniformly and continuously attached to its surface aluminum layer. The material of the aluminum coated Invar wire should be uniform, the surface should be smooth, and there should be no defects such as stains or rust.

　　The long-term operating temperature of Yin steel ultra heat-resistant aluminum alloy wire can reach 210 ℃, and the short-term temperature can reach 240 ℃, which is more than twice the current carrying capacity of conventional wire when the long-term operating temperature is 70 ℃.

　　Aluminum clad Invar core ultra heat-resistant aluminum alloy stranded wire has no restrictions on application areas, and can be used in strong winds, heavy ice areas, and large spans. It has the same sag and tension characteristics as traditional ACSR conductors, and does not require modification or reinforcement of existing iron towers. The installation method is the same as ordinary ACSR, simple and convenient.

　　Composed of aluminum clad Invar core. The ultra heat-resistant aluminum alloy part realizes the transmission of current, with a normal operating temperature of 210 ℃, which can double the current carrying capacity. The coefficient of linear expansion of the aluminum coated Invar core is only 3.7 × 10~(-6)/℃. As a load-bearing component of the conductor, it can effectively suppress sag, improve the corrosion resistance and dielectric loss of the wire, and increase the service life of the wire.
