SM busbar insulators


Busbar insulators connect current-conducting buses inside power distribution boxes and assemblies for insulation and fastening of conducting parts from the casing and panels with consequent connection of power cables for electricity distribution inside the box.

The insulator should be fixed to the mounting plate or casing with the help of a bolt on the one side; current-conducting bus is fastened to the insulator on the other side. Each bus is installed minimum on two insulators (at the bus ends). It is possible to install intermediate insulators (depending on the installation circuit and bus length).
