ELDEE manufactures a wide range of distribution and power transformers ranging from 10 KVA to 5000 KVA. 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.
ELDEE 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 upto 33 KV Class with ‘A’ Class Insulation and designed to withstand Short Circuit, & Impulse Test in accordance to IEC / BS / ANSI / IS / NEEMA.
ELDEE Standard Transformers
In order to meet the growing demand of transformers with short deliveries, ELDEE have developed a separate production system called ELDEE (ELDEE Standard Transformers). This range of ELDEE are manufactured with standard losses and in accordance to IS : 2026 latest. ELDEE can supply a comprehensive range as depicted below in short delivery periods. The second of our production system known as ELDEE Repeat transformer enables us to reproduce any of our previous transformer designs again in the shortest time with the object of keeping delivery time to a minimum. Details of Characteristics & dimensions of ELDEE standard transformers with standard fittings manufactured in accordance with IS : 2026 latest., and can be delivered in short delivery period upon order confirmation.
