Contact Surface Of Trapezoidal Rubber Ring Of Epoxy Resin Sleeve

The contact surface of the epoxy bushing manufacturer trapezoidal rubber ring works the same way as the round rubber ring. However, the epoxy bushing for transformer trapezoidal rubber ring offers improved sealing performance. After extrusion, the epoxy bushing trapezoidal rubber ring has a larger contact surface than the round rubber ring, making the trapezoidal cross-section rubber ring more effective than the epoxy resin bushing. However, the most commonly used of these two types, the epoxy resin cast bushing rubber ring, has a round cross-section.
