Structural Features
1. The tank lids have high-voltage porcelain bushings that come
with ring terminals, which can accommodate either aluminum or
copper cables.
2. The circular sewing structure of the tank cover ensures even
stress distribution and reliable sealing.
3. The ring bolts on the tank wall serve as the low-voltage bushing
and terminal and are tin-plated.
4. This item comes with a pressure relief valve that is capable of
self-sealing.
5. According to ANSI standards, the transformer's suspension hooks
at the top and bottom comply.
6. The ground terminal on the tank is a ring bolt ground terminal.
Testing
Before the single phase pole mounted transformer is delivered, we
will arrange a series of tests which help the customers to verify
the quality and ensure the safety. Generally we will perform
routine tests which include Ratio test, Winding resistance test, No
load loss and no load current test, Applied voltage and induction
voltage tests, Leakage test and so on. We will forward the test
report by specifying all these tests result with the signature of a
professional engineer on the test document. Beside the routine
tests, there are other optional tests such as Resistance test,
Temperature rise test, Sound level test and so on.
