Huco PEEK MultiBeam Couplings for Solar Panel High Voltage Capacitors

Solar Panel High Voltage Capacitor

A large household name in the Japanese consumer electronics industry recently sourced an alternative coupling to replace Huco PEEK (Polyether ether ketone) MultiBeam units used in high voltage capacitors. After supplying around 30 machines to a solar panel manufacturer, the electronics giant got a shock when an electrical discharge problem caused one of the machines to malfunction, leading to their recall to be refitted with Huco couplings.

The P.D. across the Huco MultiBeam coupling is 35,000 volts which is why the high dielectric strength PEEK material is needed (20 kV/mm in this particular application). The PEEK material has high mechanical strength at elevated temperatures, has good chemical resistance, and very good electrical insulation properties.

Special Huco MutiBeam PEEK Coupling models are available in 25, 32, and 38 mm diameters. They are designed for small amounts of angular misalignment (up to 7 degrees) and radial offset (up to 0.2 mm). Peak torque up to approx. 2.5 Nm.

PEEK MultiBeam Couplings


  • High dielectric strength PEEK material utilized (20 kV/mm) 
  • Up to2.5 Nm peak torque 
  • Up to 7 degree angular misalignment 
  • Up to 0.2 mm radial offset
