About cable glands
The transducer cable must pass through the hull using approved cable glands for the type of
vessel in question.
A steel cable gland is normally used on professional vessels with steel hulls. A bronze cable
gland can be used as an option for vessels with wood or fibreglass hulls. Vessel not to be
classified can use a cable gland made of plastic.
Note
Simrad strongly recommends that a length of conduit is fitted around transducer cable
glands made of steel or bronze and extended over the water-line inside the vessel. This
precaution reduces the danger of flooding in the event of gland failure and transducers
installed in this manner are also easier to replace.
Some vessels may experience difficulties finding suitable areas of the hull for mounting
transducer cable glands due to existing water tanks, concrete ballast or other obstacles. A
possible solution in such cases is to run the transducer cables in a steel conduit aft along
the hull until a suitable cable gland location is available. The respective cable gland can
then be installed as described in the following instructions.
Simrad takes no responsibility for the correct installation of cable glands, associated hull
modifications and/or structural support of transducer cable penetration. These activities
are subject to individual approval by the respective classification society for the vessel in
question.
