Disc strings in polluted or coastal air lose withstand margin as deposit builds up, and punctured porcelain units cannot be found on a line patrol. Toughened glass answers both: profiles that hold creepage under contamination, and a shell that shatters visibly when the dielectric is pierced.
Who It Is For
- Transmission and sub-transmission utilities
- Line EPC contractors building suspension and tension strings
- Distributors supplying line construction projects
Core Advantages
- Creepage from 190 mm to 550 mm per unit across the range
- Failing loads of 40, 70, 120, 160 and 210 kN on 11, 16 and 20 mm couplings
- Failed units are visible from the ground, so no puncture testing programme is needed
- Four shed profiles covering clean, polluted, dusty and wind-cleaned sites
Where It Is Used
- Coastal and industrial transmission corridors
- Desert routes where line washing is impractical
- Clean inland lines where a standard profile is sufficient

Glass Insulators Questions
How do we choose between standard, fog, aerodynamic and double umbrella profiles?
Standard profiles suit clean air. Fog profiles add creepage through deep under-ribs for salt and industrial fallout. Double umbrella profiles stack two skirts so fine dust cannot bridge the leakage path. Aerodynamic profiles keep an open shed that wind cleans, for remote sites where washing is impossible.
Is glass stronger than porcelain?
Mechanical ratings come from the design, not the material; both are made here from 40 kN up. The practical difference is the failure mode. Toughened glass shatters when punctured and the failure is visible, while a punctured porcelain disc looks intact.
Can glass discs be mixed with porcelain in one string?
No. A string should use one technology, one rating and one coupling throughout, because it is rated by its weakest element.
What creepage should we specify?
It comes from your site pollution class expressed in mm per kV. We publish creepage per unit for every type so you can complete that calculation and fix the unit count.
What documentation ships with an order?
Routine test records for the production lot ship with the goods, and type test reports against the applicable GB or IEC standard are available on request before the order is placed.
