Distribution & Power Transformers

L D Power Transformers manufactures a wide range of Distribution and Power Transformers ranging from 10 kVA to 5000 MVA with voltage class of 33 kV. These transformers can be free breathing or hermetically sealed. Conventional transformers are fitted with a conservator with breather for free breathing while hermetically sealed are without breathing with bolted cover. Hermetically sealed transformers are totally maintenance free and are particularly suited for use in exposed outdoor environments such as moisture, salt or dust laden atmospheres. They are used extensively in chemical plants, oil and gas terminals where poor accessibility makes regular maintenance undesirable. Transformers immersed in synthetic coolants are suitable for use indoors, with adequate ventilation, or near to the load centre where oil would not be considered environmentally acceptable. The liquid filled transformers can be supplied with cooling either by corrugations on the side of the tank or pressed steel radiators mounted on tank body. Transformers can be filled with either oil or one of several low flammability synthetic fluids such as Midel. Both types can be supplied with HV and LV switchgear incorporated into substations. The company can supply conventional/hermetically sealed/bolted type, indoor/outdoor type, pole/platform mounted 3-phase, 50/60 Hz, oil immersed, ONAN/ONAF/OFWF cooled, step up/step down, double wound with Al/Cu conductor, continuous duty transformers from 5 kVA to 20 MVA up to 33 kV class with `A’ class insulation and designed to withstand short circuit and impulse test in accordance to IEC/BS/ANSI/IS/NEEMA.
