Electrical transformers are the main equipment in the electricity cycle, from the production, transport and distribution of electricity. From power transformer which can be as big as a house up to the cell phone transformer which fit in your hand bag, they transform tension level (V in Volts) and current (I intensity in Ampère)  regarding different levels of electrical power (kVA kilovoltamperes) and have each a unique mechanical, electrical and condition in use characteristic; regarding each installation they are installed. Submitted through time to a lot of parameters, they also need protections, switchgear, relays, maintenance (spare parts, replacement parts…)

SANERGRID therefore propose a wide range of oil transformers, cast resin transformers, and dry type transformers from recognized European brands to cover a wide range of applications. SANERGRID also propose range of apparatus surrounding the transformer, such as power factor correction, harmonic filters, spare parts etc….
