ОСВР1 series transformers (single-phase, dry-type, for explosion-proof and mining equipment) rating 0.05…1.0 kV.A, with up to 660 V primary winding voltage, are intended for power supply of control circuits in mining and explosion-proof electrical equipment. Transformers may also be manufactured of 115, 230, 240, 400, 415, 440 and 550 V primary winding voltage. Transformers are applicable under moderate or tropical climatic conditions. Transformers of the same type but of varying climatic versions are identical as to all electrical parameters, design, overall and mounting dimensions and differ only in protective coating. Transformers employ a strip-wound split-type magnetic core of cold-rolled electrical steel. Transformer coils are bobbin-type, made of copper wire with heat-resistant insulation. Assembled transformers are impregnated with wet-strong insulating varnish in a vacuum impregnator. Transformer terminal clamps are arranged on insulating blocks of arc-resistant plastic. Transformers have reinforced insulation which provides better safety in maintenance and they feature enhanced resistance to network overvoltage. When agreed upon with a Customer the transformers may be manufactured with connections and voltages differing from those given in the Table below.
