Three phase transformers are used on three phase energy systems either as security - isolation type transformer or step up -down transformer, in some cases step-up and step down transformers can be produces as auto transformer for reducing the price.
Nominal power
Isolation type or auto type
Input-output voltage and current values according to duty factor
Input - output connection types ( delta - star etc )
Galvanic isolation
Input - output voltage steps
Input-output connection materials
Isolation class
Metal enclosure and ventilation
Mounting type ( horizontal - vertical ) ... Etc
Guven-is determines these technical specifications by communicating directly to the customer before designing process in order to avoid any problem. When every detail is clear a sample transformer is produced and tested by guven-is and submitted to the customer for the final approving before the ordering.

1. The transformer core is made of imported high-quality cold-rolled silicon steel sheet, which greatly reduces no-load loss and no-load current. The core is� tightly� bound to ensure the compactness and reduce noise. 2. The high and low voltage windings are� made of oxygen-free copper. The low voltage winding of 500KVA and below is of double-layer cylinder structure,� of 630kVA and above adopt double helix or four helix structure. High-voltage winding adopts multi-layer cylinder structure. 3. Dyn11 is used in the transformer connection group to reduce the influence of harmonics on the power grid and improve the quality of power supply. 4. The transformer is a fully sealed structure, with three coats of primer and one coat of finish paint applied on the inner and outer surfaces. The product is salt fog proof, moisture� proof and fungus-proofing, beautiful, durable and reliable 5. The measured noise value is lower than the standard and maintenance free under normal operation.
PION range of low voltage transformers comprise of double wound and custom designed transformers. PION transformers are available in open enclosed, oil cooled models to suit the customer requirement. Air cooled transformers are available in Open and Enclosed models. The enclosed models are supplied in sheet steel enclosures. Louvering is provided for the heat dissipation of the generated heat. Oil cooled transformers are housed in MS Tank and provided with adequate pressed steel radiators to ensure proper heat dissipation Oil cooled units are available with standard accessories viz. oil level indicator, drain plug / drain valve, earth terminals, unidirectional CI wheels, Oil fill hole and terminal covers.
