Delivery time

Normally, if with MR or ABB tap changer, the max. Deliver time about 120 days after technical drawings confirmed, if with Chinese brand tap changer, max. 90 days for any capacity and voltage range transformer.

Packing

The transformer main body usually in nude, and the accessories are packed in plywood case with steel structure, it’s worthy for ocean transportation.

Transportation

Usually, the total weight under 45 tons, it’s available by kinds of container, above 45 tons, it’s available by bulk ship.

After service

Usually, we will dispatch experienced technicians to client’s installation site for the supervision service within 15 working days after getting official information.


FAQ

1.How about the short-circuit?

Short-circuit impedance is an important item in the transformer performance index. When the transformer is fully loaded, the short-circuit impedance has an impact on the output voltage of the secondary side. The short-circuit impedance is small and the voltage drop is small.

2.How to understand transformer temperature rise?

Temperature rise refers to the difference between transformer temperature and ambient air temperature.

3.What transformer ratio need pay attention to?

Transformer ratio should be measured at each position of its tap switch.


Latest News

No-load loss mainly refers to hysteresis loss and eddy current loss (generally called iron loss) caused by alternating magnetization of the iron core, followed by no-load additional loss and copper (resistance) loss caused by no-load current flowing through the winding. The latter two items account for a small proportion and can be ignored.
