Preparing connection of high voltage cables

Preconditions for connecting high voltage cables to the panels:
• The switchgear frame is connected to the station ground.
• The window-type current transformers are mounted on the high voltage cables.
• The cables have been terminated according to the manufacturer's instructions.
Clean cable/ cable lug with a lint-free cloth.
Align cable with connection location.
Align the hole pattern of the cable lug of the cable connection.
If the C-rail (see Fig. 49, Page 61) is located in the area of the cable termination, shift the
cable bracket so that the cable clamps are located at the required distance from the
termination.
When securing the cables, ensure that the cable clamps are around the outer sheath of
the cable.The cable clamps should fit snugly, but should not compress the cable.
Secure the cable in the cable clamp.
If there is not enough space available for the window-type current transformer between
the cable clamps and the floor cover (protection against small animals), the transformer
can also be mounted underneath the optional floor cover.
