Distribution And Power Transformer - 25 Kva To 20 Mva, 33 Kv Voltage Class, Free Breathing Or Hermetically Sealed Design, Maintenance-free For Outdoor Use

Kotsons manufactures a wide range of distribution and power transformers ranging from 25 KVA to 20 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.
