Surge arresters
Surge arresters can be mounted in the cable compartment. Each
cable compartment bushing can accommodate up to three cable
connectors. When surge arresters are included, they replace one
of the power cable connectors, allowing a maximum of two power
cable connections per phase. Figure 48 shows an example surge
arrester designed for connection using tee type connectors.

Key interlocks
The XGIS design can be furnished with key interlocks.
Cable Grounding Kits
Cable grounding kits are available to facilitate grounding the cable
connections in an XGIS vertical section. These kits are designed
to provide grounding connections without disturbing the tee or
companion connectors installed on the tank phase bushings. They
include busbar connections to the vertical section ground bus.
There are three kits, each for a different cable connection configura-
tion. They are:
•
67D3091
single cable connection grounding kit (see
Figure 49
),
•
67D3092 two cable connection grounding kit (see Figure 50 ),
•
67D3093 three cable connection grounding kit ( see Figure 51 ).
