Plastics for high-voltage direct current transmissions (HVDC)

Converters for high-voltage direct current transmission have a planned operating time of 40 to 50 years. For high operating safety, constructors need reliable materials with outstanding properties. Our plastics are suitable for this. They combine high dielectrical and mechanical strength with a low moisture intake, are flame-retardant and have a high creep resistance depending on material. Use our materials to construct high-performance and reliable high-voltage direct current transmission systems.

Your advantages

Typical areas of application

Product examples

Durostone® fasteners

Durostone® fasteners are electrically insulating and anti-magnetic. Some qualities are also part-discharge-free up to high electrical field strengths, particularity creep-resilient and flame-retardant. This will support the longevity of high-voltage direct current transmission systems. More about our Durostone® fasteners

Frames of Durostone® profiles (GFRP)

Parts made of Durostone® profiles, such as frames for the inverter, combine very good electrical insulation properties with high mechanical resilience and thus contribute to the reliability of high-voltage direct current transmission systems. More about our pultruded Durostone® profiles


Clamping slings for tensioning thyristors/IGBTs

clamping slings made of Durostone® in the winding procedure for tensioning thyristors/IGBTs are characterised by their enormous tension resilience, high dielectric strength and they are flame-retardant. More about our wound parts

Resistor holders

Machined in narrow tolerances of sheet material according to customer drawings, resistor holders of Durostone® (GFRP) offer high mechanical and dielectric strengths, are TE-free, flame-retardant and have a high creep resistance. More about Durostone®

In engen Toleranzen nach Kundenzeichnung aus Plattenmaterial zerspant,  bieten Widerstandshalter aus Durostone (GFK) hohe mechanische und dielektrische Festigkeiten, sind TE-frei, schwer entflammbar und haben eine hohe Kriechstromfestigkeit. Mehr Informat
