Features
To ensure mechnical strength and heat stability of ceramic solid-core post insulator, XHDC adopt higher alumina content i.e high-strength ceramic know-how. On the basis of drawing and standard requestments, the ceramic solid-core post insulator, will be conduct the tests of routine visual inspection, verification of the dimensions, bending test, ultrasonic test etc. before left factory.
The solid-core post insulators manufacturered by XHDC with good-looking appearance, pure glaze, rational construction, good anti-cold and hot property, good low temperature resistant, good anti-earthquake, high mechanical strength, good anti-pollution characteristic, low radio interference, safe and reliable operation.
Operating conditions & classification
Outdoor post insulators apply to normal voltage of power transmission and distribution a.c. system 40.5~363kV, power distribution unit, power statin electrical equipment as current-carrying part and supporting.
The operating temperature for Solid-core post insulator is -40~+40℃, some of which can be used in the area altitude 4,000 meters.
With different ambient atmosphere clean-up extent insulator can be classify ordinary type, stain-resistance type and resistance of heavy pollution.
Design features
Metal fittings adopts cast aluminium alloy or nodular cast iron material. The surface of cast aluminum alloy flange can be anodizing processed, and nodular cast iron flange can be hot-dip galvanized.
The material for metal part adopt nodular cast iron with high mechanical stregth conducting hot galvanizing and better resistant to rust.
Product classifications
XHDC’s ceramic solid-core post insulator classify below types as per oversea and domestic customer requirments:
Ceramic solid-core post insulator divide into general solid-core post insulator, TR post-type apparatus insulators, rod ceramic insulator for a.c. contact system of electrified railways (rod ceramic insulator of cantilever type, solid-core post insulator, long rod insulator).
