Composite pin type insulator, composite 33KV pin insulator
Composite pin type insulator belongs to composite insulator. Composite 33KV pin insulator mainly applies to transmission line and other apparatus.
Composite pin type insulator tests’ preparation:
Before the tests, all samples insulators were carefully cleaned so that all traces of dirt and grease were removed and dried naturally. The surfaces of the samples were coated by a very thin layer of dry kieselguhr to destroy the hydrophobicity which would be at the degree of WC4 or WC5. Because the layer of kieselguhr was very thin, the effect of the kieselguhr on non-soluble deposit density NSDD (in mg/cm2) could be neglected.

The advantage of composite 33KV pin insulator:
Composite 33KV pin insulator consists of FRP core, silicone rubber shed, silicone rubber housing and end fittings. Silicon rubber insulator sheds provide perfect hydrophobic performance, good resistance to ageing, tracking and erosion Stable behaviour at extreme climatic conditions Long term surface hydrophobicity Suitable for polluted environment, salty atmospheres etc. Resistance to breakage and vandalism, practically unbreakable Superior anti-tracking properties High mechanical strength Ease of installation (easier handling with lighter equipment and labour at the job site) Resistance to Seismic Shock.
