10/0.4kv Dry Type Transformer

1.Product Description

The reel core fully sealed distribution transformer is a new generation of low noise and low loss transformer developed in recent years. Its iron core has no joint, greatly reduces the no-load loss and no-load current, reduces the no-load current by 60%~80%, the high and low coils are continuously coiled on the core column, the winding is tight, the concentricity is good, and the product is enhanced more. Anti-theft performance. The noise decreased by more than 10 decibels. The temperature rise is low 16-20K. Because of the continuous winding of iron core (cross section is pure circle), the orientation loss of silicon steel sheet is fully utilized, and the no-load loss is reduced by 20%~30%.
The low voltage winding with capacity in the 630~2500kVA enclosure is made of cylinder or spiral structure with high mechanical strength and balanced ampere distribution. The product has good short circuit resistance.
The positioning structure is added to the body so that it does not produce displacement during the transportation process, and all fasteners are equipped with fastener nuts to ensure that the fasteners are not loose during the long run of the product and meet the requirements of the non core lifting.
The product surface is painted, primed and topcoat after degreasing, rust removing and phosphating. It can meet the special requirements of metallurgy, petrochemical system and wet dirty area.This series of products has beautiful appearance, small size, and can reduce the installation area. It is an ideal free maintenance quality product.

Structural Features

• The iron core is made of high-quality cold-rolled oriented silicon steel sheet, the surface is specially treated with protective resin, and full-inclined seam lamination structure is adopted.
• The low-voltage coil is of foil winding structuremade of high-quality steel foil. The high-voltage coil is of layer structure formed by vacuum epoxy casting technique. Lowpartial discharge in similar product catalog;
• This model features high mechanical strength, strong short-circuit resistance, good dust-proof and anti-fouling performance. Its service life is longer than other dry transformer.
• The product’s beautiful stainless steel shell is durable and can provide better protection for the electrified parts of the transformer. Itworks well outdoors.
• With excellent moisture-proof and corrosion-resistant performance, the product is safe, fire-proof and pollution-free.It’s especially suitable for working in extremely harsh environmental conditions, and can restart without drytreatment after shutdown.
• Good heat dissipation performance and strong overload capacity enables it operate with higher capacitywhen forced air cooling.
