Low-resistance anti-corona varnish Y130 is a special protective coating commonly used for the surface treatment of power equipment such as generators and transformers to prevent corona discharge. Corona discharge is a phenomenon occurring under high electric field, which can cause local ionization and discharge of air, potentially leading to equipment damage or failure.

The features of low-resistance anti-corona paint Y130 are as follows:

1. 1. Low-resistance performance: Y130 paint has low-resistance characteristics, effectively dispersing and dissipating electric fields, reducing voltage gradients, and preventing corona discharge.
2. 2. Insulation performance: This paint has good insulation properties, preventing the flow of current and protecting the insulation system of the equipment.
3. 3. Semi-conductive performance: Y130 varnish contains materials with semiconductor properties, forming low-resistance pathways to help disperse electric fields and currents, preventing corona discharge.
4. 4. High-temperature resistance: Anti-corona varnish Y130 can withstand high-temperature environments, ensuring stability and reliability.

Low-resistance anti-corona paint is usually applied to the outer surface of equipment through spraying or brushing, forming a thin film covering to enhance the equipment’s resistance to corona discharge. It is widely used in the power plants to protect generator’s normal operation and prolong its service life.
