Willmall busbar supports hold busbars rigid at defined spacing, protecting the insulating distance under load and switching forces.
It holds the busbar rigid at a defined position and interval, keeping the conductor straight and the phase spacing correct.
Spacing prevents sag and limits deflection under switching forces, protecting clearance and insulation distance.
It is installed along the bus run inside distribution boards and switchgear, between the structure and the busbar.
Insulating support forms also provide the electrical insulation path, while metal forms are used where separate insulation already exists.
Selection matches the busbar width, the system voltage, and the required support spacing of the assembly.
