250KV·A Dry Type Transformer

Overload operation of distribution transformer Overload operation of the transformer means that the load current exceeds the rated current of the transformer. Under normal circumstances, when a transformer is operating at a small load, its insulating material cannot fully function. During continuous overload operation, the transformer will generate high temperatures, which will cause the insulation part of the winding to be burned and fall off, forming an inter-turn short circuit; at the same time, the transformer oil will produce Sludge accumulates on the tank plate, windings and core, causing poor heat dissipation of the transformer oil. This vicious cycle not only seriously affects the life of the transformer, but also causes accidents such as high-voltage breakdown and transformer burnout. Therefore, the three-phase load current should be observed frequently. The three-phase load current should be consistent. If there is any deviation, it should not exceed 10%.

FAQ

1.On site/on line Production and Quality production supervision.Customer own the product supervision right, and for each important process during the manufacturing and testing (or to be defined by customer's request), by means of on site check or on line check. Meanwhile, we valso provide traceable records for check.

2.Packing&Transportation

Wooden pallet packing or or to be defined by customer.

3. Leading time

For standard product, approximately 15 working days before delivery.

For customized product, approximately 20~30 working days before delivery.

Order quantity/customization requirements can also affect the leading time.

4.Warranty/ Payment terms

2 years of warranty at least.For the first order we normally accept T/T, 30%+70%. Regular customer payment terms to be negotiated by both parties.
