100kw resistive load bank

ventilation power of the load bank are 3 phase ( 380V + PE), total control power is 1 KW. 45 ,90%,-20,50%. Normal Operational Conditions In summer the ambient temperature is 45,humidity is 90%.In winter the ambient temperature is -20, humidity is 50% Load bank rated power error: thermal state: -4, cold state: -2. Working mode: continuous resistance tube: we selected self developed stereo-type resistance unit, the unit impedance is above DC500V 100MΩ,the withstand voltage is AC2000V/minitue,each resistance tube resistance error is ±2%. overall dimension:L600XW600XH660
