电力开关高低温箱 (CAS No.None)

Product Name:Power Switchgear High-Low Temperature Test Chamber

English Name:Power Switchgear High-Low Temperature Test Chamber

Aliases:High-Low Temperature Test Chamber, High-Low Temperature Environmental Test Chamber

Physical Properties:The chamber has an integral structure, with the refrigeration system located at the lower rear and the control system at the top. Heaters, evaporator and fan blades are arranged in the air duct layer at one side of the working chamber. The external box is made of carbon steel plate with phosphating electrostatic spraying or SUS304 stainless steel hairline finish; the internal box is SUS304 stainless steel mirror plate. The thermal insulation layer adopts rigid polyurethane foam and superfine glass fiber wool. The door frame is sealed with double-layer high/low temperature resistant silicone rubber; the observation window is multi-layer hollow tempered glass with an inner laminated conductive film and heating defrosting function; the lighting is controllable for convenient observation of test changes.

Uses:It is suitable for high-temperature and low-temperature environmental simulation tests on power switchgear and related electrical equipment, and is used to verify the heat resistance, cold resistance and operational reliability of products under extreme temperature conditions. It is widely applied in product development, quality inspection and type testing.
