3 Phase oil immersend transformer

Description

General

oil immersed power transformer,based on know-how accumulated over decade years in oil immersed distribution transformer field, Farady’s oil-immersed transformers have been supplied to various industries including semiconductor, steel work, and petrochemical.
Further, as an outstanding and comprehensive oil immersed distribution transformer solution provider, we respond to the oil immersed power transformer demanding requirements of our customers by developing and manufacturing both eco-friendly pole mounted distribution transformer and high-efficiency oil immersed power transformer.
Both oil immersed distribution transformer and pole mounted distribution transformer are designed for power centres,substations and network, also for pad mounted oil immersed power transformer, used in public distribution system, commercial building and industrial complexes
