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.
High operating safety
High safety thanks to flame-retardant properties
High creep resilience
Typical areas of application
Gas-insulated SF6 circuits
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 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 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®
