Low voltage switch cabinet use conditions: ambient air temperature must not exceed + 40 ℃, not lower than -5 ℃ Yanjin County of low voltage, and its average temperature within 24h not exceed + 35 ℃. Clean air and low pressure switch procurement, at a maximum temperature of + 40 ℃, the relative humidity must not exceed 50%, at lower temperatures and low pressure switch Puyang City, allows a greater relative humidity. Pollution Level 3. * GGD low-voltage switchgear installation site altitude must not exceed 2000m. Special conditions of use, shall be negotiated when ordering. 1. Rational design: According to escape mouth, FIG production and other electrical characteristics of the switching unit design, a combination of functional units .2 general structure, flexible assembly:. C-profile and meet a variety of structural forms .I Browse protection level and Using surround Condition Requirements .3 * can be composed of standard modules respectively protection, operation, conversion, control, standard cell module structure arbitrarily chosen group generation leather .4 Safety: The area between the isolation and functional unit incoming and outgoing adopted isolated the trouble to effectively strengthen security barrier properties than .5 technical parameters: The main technical parameters at the international level low voltage switch cabinet principle _ _ Xi promise electromechanical low voltage provided by the Henan learning Connaught Electrical and Mechanical Equipment Co., Henan Xi Connaught Electrical Equipment Co.
