All operating mechanisms are situated outsidethe SF6-tank behind the front covers with degree

of protection of IP2X.

  This allows for easy access to all operating mechanisms if retrofit or service should be required. The speed of operation of these mechanisms is independent of the operator.

  To prevent access to the cable compartment before the earthing switch is in closed position, all mechanisms can as an option be supplied with mechanical interlocks which make it impossible to remove the cable compartment covers. It will then also be impossible to operate load break/ disconnector switch to open position before the cable compartment cover is mounted properly.

  Each mechanism is equipped with a padlocking device. When adding a padlock to this device, access to operate the mechanism will be impossible. This device has three holes, the diameter of suitable padlock is 4 - 8 mm.

  All operating mechanisms are equipped with position indicators for all switches. In order to achieve true indication, indicators are directly connected to the operating shafts of the switches inside the SF6-tank. Please see shafts shown with red colour on next page.

  Operating handle has an anti-reflex system which prevents an immediate re-operation of the switch.
