Ceramic porcelain insulators

Ceramic porcelain insulators can be divided into low voltage insulators, cap & pin insulators, post insulators, low voltage distribution transmission insulators, long rod insulators and line post insulators etc.

Ceramic porcelain insulators

Transformer bushing types
Transformer bushings for outdoor and indoor are used as structure carrying on conductor through a partition from transformer tank

Low voltage insulators
These insulators are fitted on low voltage overhead lines (1.1kv) for fixing of conductor to poles and in the distribution system of the town with leakage path 150mm up to 280mm with bending load up to 18kN depend on the spindle the client is going to fix it with.

Cap & pin insulators
Cap & pin insulators are generally used on overhead transmission and distribution network to evacuate bulk power over long distance.

Pin insulator & line post insulators
Pin insulator & line post insulators are used on low voltage, medium voltage and high voltage overhead power lines for fixing conductors to tower bodies to distribute power from substations.

Stay insulators
Stay insulators give protection in the event of accidentally broken live wire that can accidentally energizing a stay wire and remaining in contact with line which doesn’t trip.

Low voltage spool & shackle insulators
These insulators are applied on low voltage overhead distribution lines for fixing of conductors to poles.
