Post insulators are divided into line post porcelain insulator, cross arm porcelain insulator and long rod suspension insulator, etc. They have characteristic of no puncture, high mechanical strength, excellent insulation and anti-pollution.
Product features:
To ensure mechanical strength and heat stability we adopt high strength ceramic formula contenting higher aluminium oxide. As per drawing and standard requirement,all post insulator will conduct visual dimension ,geometric tolerance ,ultrasonic test and four-way bending test one by one.
High-voltage insulators made by KSIpower posses beautiful appearance ,pure glaze,reasonable structure,good resistance to heat and cold, stronger for low temperature cold resistance,good earthquake.
Competitive advantages:
Reasonable insulation structure high reliability of interturn insulation.
Stainless steel flange low magnetic inductivity high resistivity.Small volume light weight.
Convenient transportation and flexible installation.
Low OSS.Low temperature rise.High mechanical strength, strong weather ability.
Outstanding crack resistance.
Low thermal expansion coefficient.
