Epoxy Bushing
Epoxy bushings are indispensable key components on the low-voltage side of transformers. They utilize the epoxy resin's excellent comprehensive properties (electrical, mechanical, sealing, and weather resistance) to provide a safe and reliable pathway for low-voltage, high-current conductors, offering insulation, support, sealing, and connection. Their characteristics of stable performance, maintenance-free operation (compared to older oil-impregnated paper bushings), and flexible design make them an extremely common and successful standard solution for the low-voltage side of modern transformers, especially dry-type and distribution transformers.
1. High Performance
Working temperature range from -40~130℃;
Excellent injection equipment to ensure no pores inside the insulation body;
Special surface treatment to ensure the bushing should not leak in long term service;
2. Rigous Test
Dielectric Tests
Basic Impulse level test: for 1.2kV class the impulse voltage is 30kV (full wave), and for 2.5kV class, the impulse voltage is 45kV (full wave);
High voltage 50Hz & 60Hz withstand test: for 1.2kV class, test voltage is 10kV/1min., for 2.5kV class, the test voltage is 2.0 kV/ 1min.
