110 Polyester Glass GPO3


Excellent electrical insulation offering good temperature range, up to 160°C, excellent mechanical properties, flame retardant and UL rated. Normally red GPO3 is the industry standard insulation used in transformers, switchgear and for many applications where its outstanding properties suit.

GPO3 Arc/Track & Flame Resistant Laminate is a mineral filled, continuous strand fiberglass-mat-reinforced thermoset unsaturated polyester material. It has been expressly developed to meet the arc, track and flame resistance requirements of the National Electric Manufacturers Association (NEMA) GPO-3 Industrial Laminate Specification (LI-1) and the physical and electrical strength requirements of (NEMA) GPO-3 (LI-1).
The mineral filler system was also specially designed to suppress smoke meeting or exceeding the stringent smoke and smoke toxicity requirements of MIL Spec MIL-M-14G (polyester) as well as MIL-P-15037E (melamine). It contains no halogen (chlorine or bromine) and will not liberate hydrogen chloride, hydrogen bromide or hydrogen cyanide when pyrolyzed.

Polyester Glass materials are especially recommended for use in the transit industry, where smoke generation and smoke toxicity are or primary concern. They are also highly recommended for use in switchgear connectors and for control panels in enclosed areas. 

No job is too big or too small, too simple or too complicated.

Thermal Insulation

Thermal Insulation is normally requested for two reasons; firstly when electrical insulation is required to work in high temperature ranges, secondly when there is need to prevent the loss of heat from a system


Electrical Insulation

Electrical insulation is chosen for its ability to resist the flow of electricity, nonconductive, it can be supplied in flexible thin films, thicker flexible laminates or rigid laminates and can be offered to suit various temperature ranges.
