KVA PROCESS Covers a wide range of oil filled distribution transformers with ON LOAD tap changer and OFF LOAD tap changer up to and including 5000 KVA range in 6 kV, 11kV, 22kV, and 33 kV voltage classes. KVA PROCESS confirming INTER NATIONAL standards of quality and safety. These transformers are assembled using the conventional stacked core . These Distribution transformers are designed and developed using latest technologies and can be provided with a variety of terminals . If distribution transformer mounted on utility pole , they are called pole mounted transformers. If the distribution transformer lies are located at ground level distribution transformers are mounted on concrete pads and locked in steel cases thus known as a pad mounted transformers .
Distribution transformers are classified into different categories based on certain factors :
Mounting location : pole mount , pad mount ,
Type of insulation : liquid immersed , dry type
No of phases : single phase , three phase
Voltages : 6 Kv , 11Kv, 33kV
Optimum efficiency is ensured by delicate proportioning of core and winding losses using CRGO M3 TO M5, MOH, Laminations electrolytic grade 99.9 % pure copper with transposition in LV coil for current sharing in parallel conductors ,electric grade press paper , boards and mineral oil. Aluminium wound distribution transformers are made by electrolytic aluminium conductor in place of copper , these type of transformers are generally manufactured up to 300 KVA as per customer requirements. Thus better regulation is achieved resulting in longer life . Careful designing also reduces noise level to the minimum.
KVA PROCESS always maintained standards with fulfillment of customers requirements. These distribution transformers are installed in a three phase distribution network (usually as a part of urban / institutional requirements)and could be used by electricity distribution companies, public utilities ,farms, factories, multiplexes and real estate ventures for further distribution or capacitive power requirements.
