Product Description

Product Description

 

High electrical strength: high-voltage transformer operation facing high voltage environment, paper covered copper wire insulation paper has high electrical strength, can withstand the high electric field strength inside the transformer, effectively prevent the discharge and breakdown phenomenon between the windings as well as between the windings and the iron core, to ensure that the transformer in the high-voltage safe and stable operation. For example, in high voltage transformers of 110kV and above, the insulating paper of paper covered copper wires is able to withstand the corresponding industrial frequency withstand voltage and impact withstand voltage tests.
Reliability of insulation: High-quality insulating paper is specially treated to have good chemical stability and anti-ageing properties. In the long-term operation of high-voltage transformers, can withstand temperature, humidity, electric field and other factors, maintain stable insulation performance, reduce the probability of failure due to insulation aging, extend the service life of the transformer.
