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

  • High operating safety
  • Long-lived
  • High safety thanks to flame-retardant properties
  • High creep resilience

Typical areas of application

  • Low-voltage switchgear
  • Medium-voltage switchgear
  • High-voltage switchgear
  • Gas-insulated SF6 circuits

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®

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

Arrange technical advice

The performance and reliability of materials for switchgears  are influenced by a variety of factors. These criteria need to be considered in order to make the right choice. Examples:

  • Mechanical stress
  • Dielectrical stress
  • Thermal stress/heat class
  • Constructional requirements
  • Dimensions and tolerances
