The infrared-transparent insulation protection cover (GAT) is the world's first special resin transparent cover that simultaneously passes "visible radiation" and infrared radiation.
The Japan Atomic Power Company conducted the research, and the Asahi Kasei Group developed and commercialized the infrared-transparent insulation protection cover.

Characteristics of Infrared-transparent insulation protection cover (GAT)
A "visual inspection" and an "infrared thermography inspection" can be simultaneously conducted from the top of the protection cover.
By making poly-olefin resin, which is normally cloudy and opaque, this protection cover solved at a stroke issues concerning existing protection covers of a switchboard etc., such as "a visible transparent resin does not pass infrared radiation" or "a resin that passes infrared radiation has poor transparency and is not suitable for visual observation."
