Introduction
Hollow composite insulators made of an elastic protective umbrella cover to withstand mechanical loads and insulating tubes, this load transfer from the metal attachment
Insulating tube. Despite these common features, materials and structures used by different manufacturers used may be different.
Although the hollow composite insulators have been used for various purposes, but these insulators on determining the size and lack of experience are still experimental.
1 Scope
This standard applies to the production of resin-impregnated fibers bear the load of the insulating tube, the elastic material (such as silicon rubber or ethylene propylene rubber) Production
The umbrella cover (outside the insulating tube) and metal accessories insulating tube constituting both ends of the hollow composite insulator (hereinafter referred to as "insulators"). this
Insulator defined in the standard for compression of internal pressurization or both. They are used for rated voltages higher than 1000V, the frequency is not high
AC voltage at 100Hz run outdoors or indoor electrical equipment or the rated voltage higher than 1500V DC device.
The purpose of the standard is.
--- Definitions of the terms used;
--- Specified test methods;
--- Specified acceptance criteria.
This standard does not specify the type of test or contamination test impulse voltage or frequency voltage, because the withstand voltage insulator not own characteristics,
Instead insulator eventually became a member of the characteristics of electrical equipment.
Note 1. The internal pressure is the persistent gas pressure greater than 0.05MPa (0.5bar) gauge. The gas may be dry air or an inert gas, such as sulfur hexafluoride, nitrogen
Or a mixture of these gases.
Note 2. There is no internal pressure refers to a gas or liquid pressure less than or equal to 0.05MPa (0.5bar) gauge. Hydrostatic pressure exceeds 0.05MPa not negotiable
The same test procedure.
Note 3. The insulator is generally used in electrical equipment in the following (but not limited to).
a) the circuit breaker;
b) load switch;
c) isolation switch;
d) grounding switch;
e) transformers and power transformers;
f) casing.
Related equipment Commission may prescribe additional tests.
