Product Description

Product Description

The role of porcelain bottles
In the transformer, porcelain bottles are the parts that play the role of insulation and support. They are able to isolate the electric field between high and low pressure, while supporting and securing wires or coils. There are three common types of porcelain bottles, namely insulators, porcelain bushings and corrugated pipes.
Switching porcelain bottle is a very important part in the main transformer, its main function is to protect the main transformer from being burned by overcurrent during normal operation. Switching porcelain bottles are usually cylindrical, usually relatively small in volume, and installed on the high voltage side and low voltage side of the main transformer.

The rated voltage value of the pillar insulator is selected according to the maximum voltage value of the equipment specified in GB156. The power frequency breakdown voltage is only conducted on type B insulators with a rated voltage of 40.5KV and below. The power frequency and operating shock humidity withstand test is only conducted outdoors. Insulators are carried out. *The moisture tolerance value of this voltage level should be agreed between the supplier and the buyer.
