Support Insulator

Post insulator from a premmiun epoxy insulator manufacturer

Support insulator or Post Insulators as the name implies, serve to electrically separate electrical conductors at different potentials, while performing mechanical functions. This ensures that the “live” parts of the equipment, with high voltages and powers, are physically separated from the structure and surroundings of the installations, which will be at ground power. Consequently, facilities and people are protected and continuity of service is ensured.

At Indisol we produce these support insulators according to the specific needs of each application, indoor, outdoor or for special environments such as SF6 or other dielectric fluids.

For different electrical stresses, from low voltage to high voltage. With mechanical specifications, from efforts to traction, bending or torsion.

To insure their quality, Insulators subject to systematic tests, both in-house and in external laboratories, where these electrical and mechanical specifications are validated.

Mounting lashings (threaded) follow the standards or customer needs.

Characteristics of our Support insulator


Safe and Reliable Distribution:

  • Electrical Insulation: Medium voltage support insulators are the
    workhorses of your distribution system. They prevent dangerous current
    leakage and malfunctions by keeping electrical conductors securely

  • Mechanical Strength: These insulators don’t just insulate, they
    also provide robust support for power lines and equipment. This protects your machinery from physical stresses and extends its lifespan.


Built to Endure:

  • High Dielectric Strength: Engineered to withstand the medium voltage
    levels used in distribution systems, these insulators prevent electrical
    breakdowns and ensure uninterrupted power.

  • All-Weather Performance: Outdoor insulators are built tough to
    handle rain, snow, extreme temperatures, and other environmental
    challenges without compromising their insulating ability.

  • UV Resistant: Medium voltage support insulators are formulated to resist degradation caused by ultraviolet radiation.

Ease and Efficiency of Support Insulator:

  • Simple Installation: Designed for quick and easy installation,
    these insulators minimize downtime during maintenance and construction projects.
    Cost-Effective Solution: Medium voltage support insulators offer a
    reliable and economical way to achieve both electrical insulation and
    mechanical support in your distribution network.
