High and low voltage control cabinet is a combination type of high and low voltage switchgear assembled using standard modules. The control cabinet is suitable for power supply systems with a rated working voltage of 660V and below for AC 50-60HZ, and is used for the control of power generation, transmission, distribution, energy conversion, and energy consumption equipment. This cabinet complies with standards such as IEC439-1 "Low voltage switchgear and control equipment", GB7251 "Low voltage switchgear and control equipment", and JB/T9961 "Low voltage withdrawable switchgear".
Technical performance Environmental temperature: -5 ℃ - -+40 ℃ Atmospheric conditions: The air is clean, and the relative humidity does not exceed 50% at the highest temperature of+40 ℃. Higher relative humidity is allowed at lower temperatures, such as 90% at+20 ℃. However, consideration should be given to the possibility of occasional condensation when temperature changes occur. The maximum elevation of the equipment installation site: 2000m. The earthquake intensity shall not exceed 8 degrees, and there shall be no serious pollution, chemical corrosion, or severe vibration.
