S2 Glass Insulation
• Hexcel Corporation S2 Fiberglass Cloth #4522 with
F81 Silane Finish.
• 30” (0.762 m) wide roll, 125 yards long (114.3 m),

Radial compensation
We can compensate for the differences in cable width, keeping the same tooling and
coil inner/outer diameters:
1.17 % width expansion
Outer radius:
during reaction
150 µm S2 Glass 
2 x 150 = 300 µm S2 Glass
130 µm  275 µm ?
2 layers of 130 µm(5.1mil) glass
Inter layer:
500 µm S2 Glass
 750 µm S2 Glass
500 µm  650 µm ?
3 layers of 206 µm(8.1mil)
glass + binder
