::.Welcome to Esteem..

	Esteem manufactures Ultra Isolation Transformers upto 200KVA rating. The isolation transformers are air-cooled versions suitable for indoor installations. The main application of isolation transformers is for protecting the sensitive loads from spikes, surges and ground noises generated in an electrical system. The attenuation offered is upto 120dB.
	Esteem also offers a variety of Auto Transformers for AC voltage conversions. The general available ratings are from 1KVA to 200KVA, all in air-cooled versions.
