25KV composite polymer distribution deadend insulator DS-28
25KV composite polymer distribution deadend insulator DS-28 is clevis and tongue type high voltage insulator. The end fitting is different from ball and socket, it need connect with other clevis types of distribution lines fittings and then installed on the overhead lines. 25KV composite polymer distribution deadend insulator DS-28 is normally used in the countryside and towns.
DS-28 is used for 25kv medium voltage system, and ANSI C29.13 is the main internation standard for deadend insulators. It has detailed description of how to do tests on the 25KV composite polymer distribution deadend insulator DS-28 and which tests need to do on the composite insulator.
Prototype tests, type tests, quality conformance tests and routine tests are the main types on ANSI C29.13. This standard is the general introduction for the tests which need to be done on 25KV composite polymer distribution deadend insulator DS-28, and ANSI C29.1 has more detailed procedures for the insulator test and when the tests are passed.
