All product familiesEngineering DNA
Two material-level advantages set silicone composite insulators apart from porcelain and glass — and drive every line of our product specification.
Triple junction point
Silicone rubber is directly moulded onto the ECR rod and permanently bonded to each fitting. Air and water cannot reach the triple junction point, eliminating the partial-discharge pathway that causes ageing in conventional insulators.
Up to 420 kV
Rounded end-fitting geometry, validated by in-house field simulation, suppresses electrical-field concentration at the live end. The result is controlled corona behaviour and longer service life on transmission-class voltages.
Patents & Innovation
Innovations developed in-house, registered, and already deployed on live transmission and distribution networks.

Materials science
A composite insulator is not one material — it is three, bonded so that air and water never reach the interface.
Electrical-grade, corrosion-resistant fibre-reinforced plastic core. This is the mechanical load path of the insulator — every kilonewton of line tension runs through it. ECR grade resists the brittle-fracture mechanism that ends the service life of ordinary FRP cores.
High-temperature vulcanised silicone, moulded directly onto the rod. Hydrophobic and UV-stable, and — the property that decides service life in a polluted zone — fully recoverable: the surface regains its water-repellency after contamination rather than degrading toward tracking and erosion.
Forged steel end-fittings, hot-dip galvanised for decades of atmospheric corrosion resistance. The geometry is rounded — validated by in-house field simulation — to suppress field concentration at the live end and control corona behaviour up to 420 kV.
Where rod, housing and fitting meet. Silicone is permanently bonded to both, so air and water cannot reach the junction — eliminating the partial-discharge pathway that ages conventional insulators from the inside out. This is the whole argument for composite over porcelain, in one interface.

Why Taban Niroo?
The values below are not a marketing framework. They are the operating principles that have guided the company through twenty-five years of power-sector work across Africa, South America and the Middle East.
01
We anticipate the future needs of the power industry and invest in research, equipment and people long before the market demands them.
02
Three registered patents and a continuously expanding product range mean our customers build their projects on proven, domestically-engineered technology.
03
Every product family is designed and type-tested to IEC 61109, 62217, 61466, 60120 and 60471 in accredited laboratories, from 6-1000 kV.
04
We actively partner with utilities and EPC contractors to solve field problems — bespoke fittings, site audits, pollution studies — well outside a normal supply contract.
05
Long-term client relationships are built on transparent commercial terms, honest engineering advice and consistent product quality over decades, not quarters.

Chief Executive Officer
October 2024
It gives me immense pleasure to present this message from Taban Niroo — an innovative, modern, forward-thinking organization I have had the honor of leading for the past quarter of a century. Having dedicated more than forty years of my life to the Power & Electricity industry, I share our achievements with apt pride.
Since our inception, our products have been engineered to excel — sometimes beyond world standards — through research, perseverance, and an unwavering desire for perfection. Innovation and creative solutions have allowed us to meet the diverse challenges of our clients.
Over the last quarter of a century we have doubled our workforce, fostered a culture of diversity, and established ourselves as a prominent manufacturer in the power and electricity sector in Iran, rivalling many multinational companies. Today, we proudly serve major clients across Africa, South America, and the Middle East.
At Taban Niroo we will continue to supply products our clients can use without any concerns — and keep improving the quality of our products and craftsmanship, as well as production efficiency, to increase our credibility.
