Phase fixed points

Ball connection studs can be used as phase connection and busbar gland

Phase fixed points are essential components in electrical systems that serve to mechanically fix current conductors. They play an important role in the absorption and transmission of electrodynamic forces that can be caused by short-circuit currents.

Ball connection studs as phase connections offer particular advantages:

  • They enable a flexible and at the same time secure connection of the conductors
  • Thanks to their spherical design, they can compensate for movements in different directions
  • They ensure even power transmission and current distribution

The busbar gland is a critical element of the fixed point. It must:

  • Maintain the required tightening torque permanently
  • Be designed to be vibration-proof
  • Ensure a low transition impedance
  • Be corrosion-resistant

During installation, particular attention must be paid to correct installation and the specified tightening torque in order to ensure full functionality of the phase fixed point.
