Transmision Insulators
Our insulators cater to the entire spectrum of sub-station and transmission insulators. We specialise in the production of high strength equipment porcelains for use in SF6 circuit breakers, instrument transformers, condenser bushings, disconnectors, and high-end transmission products up to 765 KV system voltages.

Pin Insulators
Pin insulators of one piece or multipiece construction are widely used in low cost distribution lines. Multipiece construction makes these insulators less vulnerable to damage. A multipiece insulator can normally withstand the line voltage for a considerable time without difficulty even if one shell is broken. These insulators are available with creepage path to meet various requirements of pollution.
Multi Cone Post Insulators
Cap and pin type insulators are designed mainly to support disconnecting switches, busbars, conductors, and equipment for substations. They are capable of being stressed in tension, compression, flexion, torsion and combined stresses upto the specified limits. These insulators are more economical than other types of insulators used for similar applications.
Substation, traction, line post insulators
Solid Core Station Post Insulators
Solid core station post insulators are comparatively lighter and have smaller diameters than other types of post insulators of similar voltage class. These are ideally suitable for compact installations which result in slim and neat appearance and afford better harmony with other modern apparatus in any EHV/UHV substation.
Solid core station post insulators have superior antipollution performance, low RIV, better arc resistibility and lower deflection under cantilever load.
Long Rod Insulators
Long rod insulators are absolutely puncture-proof, possess high arc resistibility and are free from cement growth trouble.
Long rod insulators can be used at suspension and tension locations both as single and multiple strings as per system requirements.
Standard long rod insulators have high strength in compression and tension, provide higher leakage distance with superior self-cleaning characteristics and are lighter when compared to disc insulator strings of similar voltage class.
These insulators are useful for reducing the width of the right of way with consequential economy in the design of the overhead line.
Apparatus Porcelain Insulator
The design concept for hollow porcelains is dependant on the complete design of electrical equipment such as SF6 circuit breakers, air-blast circuit breakers, minimum-oil circuit breakers, instrument transformers, condenser bushing and lightning arresters.
The porcelains are designed in consultation with the manufacturers of equipment so as to meet the electrical and mechanical requirements. The manufacturing possibilities of shape, size and dimensional tolerances of large hollow porcelains comply with international standards.
Solid Core Line Post Insulators
Solid core line post insulators can be used as support for conductors on cross-arms of transmission and distribution line poles. These insulators are recommended for polluted zones and areas prone to vandal damages.
Even if the insulator shed is damaged, there will be little decrease in flashover voltage and power supply will not be disturbed. The damaged insulator can be left in service and replaced conveniently. No change in cross arm is necessary, if pin type insulators are replaced by line post insulators during maintenance.
