Porcelain tie-top line post insulator is Orient Power tested in a special four quadrant cantilever test at 50% of rating. The tests are conducted at 25% above the maximum recommended working load on all insulators....before they are shipped! Orient Tests for Porcelain Product Performance are before Product Shipment.

Orient tests products at each and every stage of production operations: Beginning with raw material tests....ultrasonic....moment testing....cantilever testing....and, finally, the ANSI 57-6 porcelain line post insulators are sampled and the samples are tested to destruction! The people of Orient are dedicated to quality and product performance!


Orient Power will do all series of tests for our solid core line post insulators before selling. The line post insulator tests include design tests, quality conformance tests, cantilever-strength test and routine tests. More details about ANSI 57-2 porcelain line post insulator or solid core line post insulators can be shown for you through emails or online contact.
