Introduction of transformer and other products
Shanghai Liyou Electrification Co.,Ltd is specialized in design, production, and sales of isolation transformer, self-coupling transformer, unpowered complimentary device, harmonic filtering device, suppression device of harmonic current, soft starter, and anti lightning device of the power supply.
I、Introduction of the dry-type isolation transformer
This series of transformers are suitable for the isolation of the controlled power and power supply of the normal electrical appliance in the machines and mechanical equipment in industry and mine and enterprises with the class AC 50-60Hz voltage. The product is suitable in places needing transforming and safe isolation of the city electricity voltage. DG series of single phase and dry-type transformer has a capacity from 1KVA to 400KVA, while the SG series of three phases and dry transformer has a capacity from 2KVA to 600KVA. The isolation classes are B and F.

II、Introduction of the self-coupling transformer
ODG and OSG series of single and three phases and self-coupling transformers are those with at least two windings and a common connection point, but without safe isolation features. Their price is slightly lower than the DG and SG series of single and three phases and dry-type transformers. Their size is slightly smaller, only suitable to places needing to transform the city electricity voltage, but not needing safe isolation. ODG series of single phase and self-coupling transformer has a capacity from 1KVA to 400KVA, while the OSG series of three phases self-coupling transformer has a capacity from 2KVA to 600KVA.
