Three Phase Distribution Transformer

OLT manufactures a wide range of distribution transformers ranging from 30 KVA to 5000 KVA with all voltage class and upto 34.5 KV. These transformers can be free breathing, fitted with a conservator or hermetically sealed. The liquid filled range can be cooled by either tank - mounted plate radiators or by corrugations on the side of their tanks. The latter being known as conventional type transformer. Free breathing units, with or without conservator are normally oil-filled, while hermetically sealed transformers can be filled with either oil or one of several low flammability synthetic fluids. Both types can be supplied with HV and LV Switchgear and incorporated into substations.

Our conservative design philosophy, tightly controlled product configuration and consistent manufacturing processes ensure that every OLT customer gets the highest quality product possible.
