1000-5000A Epoxy Resin Bushings
Descripution
Oukepu epoxy bushings have passed many tests, according to IEC60137
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, the test voltage is 10kV/1min, for 2.5kV class, the test voltage is 2.0kV/ 1min.
Mechanical Strength Tests:
- Leakage test,
- Stud push-out test,
- Study torque strength test,
- Cantilever test
- Flange torque test.
The environmental test:
It includes a thermal cycle test. The tested temperature range is -40~130℃, withstands 20 cycles.
Our 1000A–5000A Epoxy Resin Low Voltage Bushings are engineered for high-performance applications in dry-type transformers, switchgear, and other transformer-filled apparatus. Manufactured using advanced epoxy resin technology, these bushings offer superior electrical insulation and mechanical strength, ensuring reliable performance in demanding environments.
All design tests are performed in accordance with the customer’s requirements or on the agreement between Oukepu and the customer.
We have the copies of the test report for reference on the customer’s request.
