High Voltage DC Contactors Encapsulated Epoxy Resin Potting

High Voltage DC Contactors Encapsulated Epoxy Resin Potting  

High Voltage Contactor Series is designed to meet the demands of high-voltage and high-current DC applications.

High Voltage DC Contactor is subjected to high peak currents, which produces a strong arc when disconnecting a large DC current, which can easily lead to damage to the contact, so that it cannot extinguish the arc within milliseconds. Injecting arc extinguishing or inert gas around contacts and shrapnel, and casting epoxy resin to keep it in a sealed environment, is the industry's solution to this problem.

Pouring of epoxy resin ensures that the inert gas is in the air tight chamber of the high voltage DC contactor, so that the charged gas will not escape, maintain stable arc extinguishing ability, reduce the possibility of contacts melting due to arc burning, avoid oxidation of internal metal parts, and improve the reliability and service life of the product. 

Our epoxy resins are used in various transformers, relays, high-voltage DC contactors, and are widely used in electric vehicles, DC charging stations, energy storage, solar photovoltaics, and wind power generation. It is characterized by:

• Black and white, two colors are available

• It has a strong adhesion ability to the substrate

• Passed the harsh 1000H test

• Passed withstand voltage and leakage current tests
