11KV 3 Phase Distribution Oil-immersed Power 500KVA Small Electrical Transformer

Product Specification

oil-immersed transformer, 30-2500KVA,10KV series,3 phae/full sealed/double winding

Introduction

This type of transformer adopts high-permedibility cool-rolling si-steel piece as iron core.It is  processed with big fill factor and there is no spacing inside the mangnetic path. The HV and LV coil is continuously winded around the core with good concentricity and compact winding. The

product is of low con-sumption and slight noise pollution by combining new generation of technolgy good performance and energy saving. It is widely used in power distribution system.

S11-M oil immersed power transforme 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%.

Compared with S9 transformer, the S11 transformer reduces the no-load loss by about 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 corrugated oil tank is adopted in the transformer, and the oil conservator is cancelled, the box cover and the box edge are completely welded or fastened by bolts, thus prolonging the service life of transformer oil.

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.

A fully sealed transformer oil tank is used. The pressure release valve, signal thermometer and gas relay are installed according to the standard, so as to ensure the safe operation of the transformer. This series of products has beautiful appearance, small size, and can reduce the

installation area. It is an ideal free maintenance quality product.

Material

Oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and the electric performance is better.
High-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
High-quality wooden laminating insulation pieces, which won’t split or move even under the influence of short circuit.
Thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.
High-quality rubber sealing material, which can prevent the transformers form aging or leakage.

ATTENTION:

1.The payment term: We accept TT,30% deposit and 70% balance against copy of BL.
2.The delivery time: Usually it will take about 15-20 days.
3.The standard of package: Usually use strong plywood case for protection.
4.The material of transformer: We have two types, one is with copper and another one is with aluminum. It depends on your requirement. In fact, those two have difference if normal work well. Only except the long life. Copper is better and also higher price.

5.The logo: If you have good quantity, it absolute no problem to do OEM.
