Cable glands are mechanical cable entry devices and can be constructed from
metallic or non-metallic materials. They are used throughout a number of industries
in conjunction with cable and wiring used in electrical instrumentation and
automation systems.
Cable glands may be used on all types of electrical power, control, instrumentation,
data and telecommunications cables. They are used as a sealing and termination
device to ensure that the characteristics of the enclosure which the cable enters
can be maintained adequately.

Preparing cables for termination
Whenever a cable shall penetrate a cabinet or a bulkhead using a cable gland, the
termination of the cable must be prepared.
Prerequisites
Electrical installations can only be done by certified electricians. All necessary tools and
instruments required must be available. The installation shipyard must prepare detailed
drawings of the electrical system, and identify each cable.
Context
Cable glands are used whenever a cable passes through a watertight bulkhead or into a
cabinet, to seal the opening through which the cable passes and to protect the cable from
abrasion on the edges of the hole. The cable glands are not supplied with the EC150-3C.
Note
There are many different types of cable gland on the market. This procedure describes
the types used (now and previously) as standard in the units manufactured by Kongsberg
Maritime. Even though the cabinets from Kongsberg Maritime may be prepared for
specific types, the installation shipyard will be responsible for selecting cable gland
types and installing them.
Procedure
1 Ensure all the cables to be connected are completely isolated from any power
sources.
For safety reasons, switch off and remove the power supply fuses from any units or
systems into which the cables are already connected.
