Ref: GPO3. NEMA LI-1.
 1. COMPOSITION AND PRESENTATION
GPO3 is a stratified insulator made from fibre glass blanket and polyester resin and resistance to flame ( V-0 ).
At delivery time the presentation of the sheets is as follows:
- Maximum sizes: 1020 X 1220 mm. - Thickness: From 0.8¨C50 mm
- Colour: Red - Surfaces: Shining
- On demand we can deliver strips or finished components.
2. PROPERTIES AND APPLICATIONS
- Very low hygrometric susceptibility - Small losses at high frequency
- Excellent mechanical properties - Good dielectric properties
- High resistance to flame ( V-0)
Support for muddy, separators in transformers and electric machines, pictures , etc.
