Withdrawable cabinet is composed of a fixed and equipped with switches and other electrical components of major mobile unit parts, removable partial shift change to light, after moved to reliable positioning, and the same type and size of drawers with reliable proof swap electric box model, withdrawable part in the cabinet and fixed processing method is basically similar in the cabinet. However, due to exchange requirements, the need to improve the accuracy of the cabinet, the relevant part of the structure have sufficient adjustment amount, as part of the mobile unit, to both shift change, but also reliably Holds the Key Components proof distribution box cheap, So have a high mechanical strength and high precision, the relevant section will also have sufficient amount of adjustment. * The ambient air temperature must not exceed + 40 ℃ Explosion distribution box manufacturers, not lower than -5 ℃, and its average temperature within 24h not exceed + 35 ℃. * Clean Air proof distribution box, at a maximum temperature of + 40 ℃, the relative humidity should not exceed 50 percent, at a lower temperature allows a greater relative humidity. * Pollution grade 3. * Installation site altitude must not exceed 2000m. * Special conditions of use, shall be negotiated when ordering.
