Aerodynamic Profile
Aerodynamic Profile Toughened Glass Insulators
Wide open sheds with no deep ribs, shaped so wind takes the dust off instead of packing it in.

The Problem
What This Profile Is Solving
In desert and sand-dust regions a ribbed profile is a dust trap. Fine mineral dust packs into the under-ribs, resists natural washing, and abrades the glass surface. Creepage measured on paper stops matching creepage available in the field.
Who Specifies It
- Utilities building lines across arid and semi-arid terrain
- Solar and wind evacuation lines in desert basins
- Operators facing seasonal sand and dust storms with little rainfall
Why This Geometry
Core Advantages
- Open shed geometry lets wind self-clean the surface between storms
- 420 mm disc diameter at 160 kN spreads load over a smooth profile
- 380 mm creepage without deep dust-trapping ribs
- Resistant to UV and wide diurnal temperature swings
Application
Where Aerodynamic Profile Discs Are Installed
Desert and semi-desert transmission corridors
Renewable energy evacuation lines in arid basins
Lines with strong prevailing wind and low annual rainfall

Answers
Aerodynamic Profile Questions
Why does the aerodynamic profile have less creepage than the alternating profiles?
Because creepage on paper is not creepage in the field once ribs pack with dust. The open shed keeps its 380 mm effective because wind removes deposit between storms.
What diameter is the aerodynamic disc?
420 mm at 160 kN, the widest in our range. Check tower clearance and string wind load against that figure before specifying.
Does it handle UV and temperature swing?
Toughened glass resists UV radiation, moisture and temperature changes, which is why the profile suits arid regions with intense solar exposure and wide day-to-night variation.
