Aerodynamic Toughened Glass Suspension Insulator XYAY Series




Glass Suspension Insulators
Product Overview
An aerodynamic profile toughened glass disc for transmission line suspension strings, tested to IEC 60383. The shed is shaped so wind carries dust off the surface instead of letting it settle, which is why this profile is specified in desert and heavily polluted corridors. Rated mechanical failing load is 120 kN, creepage is 365 mm, and a disc weighs about 6 kg.
- IEC 60383
Key benefits
Why Buyers Choose This Part
- Aerodynamic shed lets wind self-clean the surface between washes
- 120 kN rated mechanical failing load for long-span suspension strings
- Toughened glass shatters visibly when punctured so faulty discs are found from the ground
- 365 mm creepage with 130 kV power frequency puncture voltage
Application scenarios
Where It Is Used
- Desert and semi-arid transmission corridors with wind-blown dust
- Coastal lines where salt deposits build between rain events
- Suspension strings on lines where helicopter inspection is the main survey method
- Retrofit of porcelain strings that need fewer wash cycles
Who it is for
Who It Suits
- Transmission line contractors building in polluted or arid regions
- Utility line engineering teams specifying string hardware
- Distributors supplying overhead line construction projects
Problems it solves
What Goes Wrong Without The Right Part
- Pollution flashover on strings that cannot be washed often enough
- Defective discs that cannot be spotted during a ground or aerial patrol
- Strings that need too many units because the disc rating is too low
- Uncertainty about test evidence when a project specifies IEC 60383
Technical features
How It Is Built
- Specification and tests in accordance with IEC 60383
- 120 kN rated mechanical failing load
- 365 mm nominal creepage distance
- 50 kV dry and 40 kV wet power frequency withstand voltage
- 130 kV power frequency puncture voltage
- 6 kg net weight per disc

Comparison
How It Compares
| Standard profile glass disc | The aerodynamic shed sheds wind-blown dust instead of collecting it, so wash intervals stretch on dusty lines. |
|---|---|
| Porcelain disc insulator | A punctured glass disc shatters and is visible from the ground, while a punctured porcelain disc often looks intact and has to be found by instrument. |
Use guide
Before You Order And After It Arrives
- Check the ball and socket size against your existing string hardware before ordering
- Fit split pins fully home on every coupling
- Do not lift a string by a single disc during stringing
- Record the disc rating used on each span for future maintenance
Questions
Aerodynamic Toughened Glass Suspension Insulator XYAY Series Questions
What standard is this insulator tested to?
Specification and tests follow IEC 60383.
What is the rated mechanical failing load?
120 kN for this rating. Other ratings in the XYAY series are available, so send the string design and we will confirm which disc fits.
Why glass instead of porcelain?
A punctured toughened glass disc shatters and is obvious during a ground or aerial patrol. A punctured porcelain disc usually looks intact and needs instrument testing to find.
What is the creepage distance?
365 mm nominal, with 130 kV power frequency puncture voltage.
How much does one disc weigh?
About 6 kg.
Do you supply the complete string or only the discs?
We supply the insulators. Send your string arrangement on WhatsApp and we will confirm the coupling sizes we can match.
