Composite post insulator
As one of the main product of China Orient Power, the composite post insulator is also one of the most important products in our company. Except the composite post insulator, we also provide the composite suspension insulator, polymer line post insulator, polymer cross arm insulator, composite railway insulator, and composite pin insulator. In this article, we are focusing on the test method of the composite post insulator.
Type tests:
Type test is one of the most elemental tests of the composite post insulator’s tests. An high voltage insulator type is electrically defined by the arcing distance, creepage distance, shed inclination, shed diameter and shed spacing.

The electrical type tests shall be performed only once on insulators satisfying the conditions above and shall be performed with arcing or field control devices (which are generally necessary on composite insulators at transmission voltages) if they are an integral part of the insulator type.
Furthermore, when the insulator designs characteristics changes, it also requires a repeat of the electrical type tests.
An insulator type is mechanically defined principally by a maximum SML for the given core diameter, method of attachment and coupling design.
The mechanical type tests shall be performed only once on insulators satisfying the criteria for each type.
