Testing to Confirm Performance
In order for the polymer insulators to be used as insulator strings, tests were also conducted to confirm their performance as V-string suspension devices or tension devices. The picture shows a composite tension insulator string.

Representative Test Results
The main tests for confirming the performance of the polymer insulators are:
◆ Composite insulator durability - Test of interface and connection of the end-fitting;
◆ Power arc-withstand characteristics;
◆ Bending characteristics; and
◆ Vibration fatigue characteristics: Longitudinal vibration-fatigue test

Test of Interface and Connection of the End-fitting
The interface adhesion between the housing rubber and the FRP core in the vicinity of the end-fitting is considered one of the most crucial aspects of polymer insulator manufacture, and as a means of verifying its suitability.

Orient Power does Test of Interface and Connection of the End-fitting in accordance with IEC61109 standard.
