Plastics for switchgear

Switchgear must be operationally safe even after several thousand switching cycles and with electrical currents at several hundred kilo ampere. Constructors need high-performance materials for development that meet high electrical and mechanical requirements. With Durostone® (GFRP), we offer a material with outstanding mechanical and electrical resilience that is used specifically for low-, medium and high-voltage switchgear. It thus contributes to the constructions of high-performance and operationally safe switchgear.

Your advantages

Typical areas of application

Product examples

Power rail holders

Power-rail holders made of Durostone® (GFRP) machined to narrow tolerances support reliability of switchgear with their high mechanical and electrical strength, low water intake and high creep resistance. More about Durostone®

Phase separators

Phase separators of Durostone® combine high form stability with high dielectrical strength, thus resisting the high electrical and mechanical stresses in switchgear in the long term. More about Durostone®

Trovidur® EC-N (PVC-U) sheets in electrical switchgear

Trovidur® EC-N sheets have high electrical resistance and are therefore particularly suitable for constructions in the electrical and electronics industry. The material passes the glow wire test according to DIN EN 60695-2 with outstanding results. This enables them to be used in electrical switchgear. With their high electrical dielectric strength Trovidur® EC-N (PVC-U) sheets are also suitable for use as partition plates in medium voltage switchgear.

Switching rods

Switching rods in SF6 insulated switchgear made of Durostone® (GFRP) offer high mechanical strength and high creep resistance while at the same time resisting high dielectrical stress. More about Durostone®

Frames and housings

Frames and housings for switchgear produced in the pultrusion procedure offer high electrical and mechanical strength. More about our pultruded profiles
