All Daheng made epoxy bushings have the working temperature range from -40~130℃. It is very important for the transformers which served in very cold area and very hot area. It is also very important especially to the solar/wind generation transformers which usually withstand heavy current in sunshine hot noon and suffer very cold weather in the cold night in those extreme environment, Daheng epoxy bushing had put up very good records. Daheng has set up excellent injection equipment to ensure no pores inside the insulation body. Daheng has effective test equipments and test procedure for the epoxy bushings. Each bushing must be tested before it finished in factory. Daheng has special interface treatment technique (it is said DIT) for the bushing stud surface treatment to ensure the bushing should not leak in long term service. 2.Rigorous Test Daheng epoxy bushings have passed many test, 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, test voltage is 10kV/1min., for 2.5kV class, the test voltage is 2.0 kV/ 1min. Mechanical Strengthen Tests Leakage test Stud push-out test Stud torque strength test Cantilever test Flange torque test Environmental test It includes thermal cycle test. The tested temperature range is -40~130℃, withstand 20 cycles. All design tests are performed in accordance to the customer’s requirement or on the agreement between Daheng and the customer. We have the copies of test report for reference on customer’s request. We also support customers' specified third party type test report. Accsessories Clamp: All bushings supplied with one piece of AL clamp. Seal gasket: There are seal gaskets which made from NBR & HNBR for customer’s selection.
