Insulators (Porcelain, Glass, Polymeric, Composite)

Disc-Type Insulators

Supply for transmission lines and substation 0.4KV-1150KV All meet international industry standards, such as IEC, BS, ANSI as well as market requirements.

Long-Rod Type Insulators

Mechanical strength up to 400kN

Normal or alternating shed design with aero-dynamic type profile as per customer’s requirements

Line-Post Insulators

Suitable for both low voltage and high transmission lines of up to 150kV

Can have a single stag and as well as multiple stags

You can use two or more post insulators, one above the other for high-voltage applications

The metallic arrangement is available both at the top and bottom of the insulator

Pin-Type Insulators:

This insulator is used in power transmission lines for up to 33kV

Mechanical failing load (bending) 13KN

Nominal creepage distance 325MM , ANSI STANDARD

Spool Insulators:

LV 53-1/2/3/4/5 porcelain spool insulator, Mechanical Failing Load KN 9-27KN

Strain / Guy Insulators:

Egg type strain insulator has low-voltage applications and is used in utility-pole guy cables to restrict any voltage on the guy caused by an electrical defect on the pole from reaching the lower parts accessible to the citizens. For 66 kV, 230 kV, and 115 kV AC lines,

High-voltage strain insulators. The number of insulator skirts changes based on the voltage value and atmospheric conditions.For radio antennas, we use a pyrex-glass strain insulator

Dead-End Insulators:

Dead-end Insulator is a kind of Polymer insulators and deadend insulators are used on overhead lines operating at up to 69kV. These insulators are used to support line conductors in suspension or deadend modes such as line terminations,angles, and tangents. These insulators can be used with bare or covered conductors.


Silicone Polymer Cutouts: 15KV, 27KV, & 36KV Loadbreak & Non-Loadbreak 100AMP or 200AMP

Railway Insulators:
