Note
Observe relevant requirements and guidelines from the classification society, and make
sure that the conduit is properly supported, strong and watertight.
Finalize the steel conduit installation before you pull the transducer cable through it.
Make sure that there are no spatter, sharp edges or protruding objects that can damage
the transducer cables. If a cable is damaged, and penetrated by water, the transducer
will be damaged beyond repair.
Once the transducer is installed, the transducer cables – with the large transceiver plug
– must be pulled through the steel conduit. If you must introduce bends on the steel
conduit, take the size of the transceiver plug and the minimum cable bending radius into
consideration. Once you have pulled the cable up through the steel conduit, seal the top
of the conduit with a Roxtec (or similar) seal.
Steel conduit minimum dimensions
The dimensions of the steel conduit must be specified and/or verified by the relevant
maritime authority and/or classification society. The minimum dimensions are:
•
:
Inside diameters
– With transceiver plug mounted: 182 mm
– Without transceiver plug: 110 mm
•
