Cable glands and termination procedures
Cable glands are used to attach and secure the end of a cable to the equipment. Cable
glands may also be used for sealing cables passing through bulkheads or gland plates.
About cable glands
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.
There are many different types of cable gland on the market. The cable glands are not
supplied with the system.
Note
Even though the cabinets from Kongsberg Maritime may be prepared for specific types
of cable glands, the installation shipyard will be responsible for selecting cable gland
types and installing them.
A cable gland (in the U.S. more often known as a cable connector or fitting) is
a device designed to attach and secure the end of a cable to the equipment. A
cable gland provides strain-relief and connects by a means suitable for the type
and description of cable for which it is designed—including provision for making
electrical connection to the armour or braid and lead or aluminium sheath of the
cable, if any. Cable glands may also be used for sealing cables passing through
bulkheads or gland plates.
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.
