Locomotive traction transformer sealing gasket

Traction transformer is the core equipment of locomotives with the function of transforming 25kV voltage into suitable voltage for locomotive power supply, which is named as the “heart” of locomotive and decides the safe operation of locomotives. However it’s confronted with complicated working and environmental conditions such as dust, rain, snow and mud etc. Locomotive traction transformer tank cover and cooler’s rubber gasket are very important to protect the “heart” of locomotive. The gasket need to withstand different weathers, continuous and changeable compression set. What’s more, all the components should reach V0 level fireproof and don’t produce harmful gas when flaming. SHIRE locomotive traction transformer sealing gasket is widely used in railway system and takes ups No.1 turnover in the market by its excellent performance.
