Porcelain pin type insulator,11KV porcelain pin type insulator manufacturers
Porcelain pin type insulator is made by the wet process using high grade raw materials, which is produced by one of popular leader 11KV porcelain pin type insulator manufacturers.
Porcelain pin type insulator materials:
The basic raw materials that go into the manufacture of porcelain pin type insulators are naturally occuring clays and minerals like quartz and feldspar. The coarsely-powdered materials are ground to the required particle size in ball mills. The moisture content is reduced in filter process to obtain solid cakes. The cakes are fed into the pug mills. The void free pugs that are extruded from the pug mills are then pressed into shape and glazed after drying. Porcelain pin type insulators which are thoroughly inspected before glazing are fired in the tunnel kilns.

Porcelain pin type insulator tests:
The body composition developed over the years ensures excellent mechanical and electrical characteristics. 11KV porcelain pin type insulator is provided with Zinc thimbles suitable for Small and Large Steel Head Pins. Above Pin Insulators are subjected to a full series of type tests such as Impulse and Power Frequency Tests, Temperature Cycle Test, Mechanical (cantilever) test, Puncture Test & Porosity Test. Full quality control is exercised at all stages of manufacture. Some of the tests conducted on all insulators during manufacture are crack detection before firing, high frequency high voltage test besides routine electrical test at power frequency, in addition, porosity and temperature cycle tests are conducted for each batch of manufacture.
