Mining Transformer

Main Technical Data & Characteristics: Mining transformer KS9 series ore transformer is applied to certain places with gas,but no explosion danger,like center substation of coal borehole,pit bottom,general air inlet duct and main air inlet duct. It also could be applied to moist environment,like tunnel. Main Features: Safety Low no-load loss Low no-load current Low noise The altitude of installation should not be over 1000m The surroundings temperature should not be over 40 degree centigrade The relative humidity of surroundings should not be over 95%(at+25 degree centigrade) The surroundings of installation without strong shake,and gradient should not be over 10degree Detail parameters in table: Rated Capacity (KVA)Voltage combinationConnection SymbolNo-load loss (W)On-load loss(w) 75No-loadCurrent %Shirt-circuit Impedance%HV (kv)LV (kv)506.66.360.6930.4Yy0Yd01708702.04.58024012501.810029015001.616039022001.420047026001.325056030501.231567036501.140080043001.050096051001.0630115062000.9Note: we can design and manufacture special transformerascustomers' requirements.Ordering Instruction: 1.product model; 2.rated capacity; 3.voltage range; 4.regulation range; 5.frequency; 6.connection symbol; 7. technical requirements for special transformer.
