Steel conduit quality and shielding
The steel conduit must be unbroken and watertight from the transducer to above the
water line. From there, the cable can be pulled further, or a junction box can be installed
to facilitate further connections.
Note
The steel conduit must act as a continuous electrical screen all the way.
If two or more transducers are installed close to each other it is possible to pull their
cables in the same steel conduit, provided the conduit diameter is increased accordingly.
However, for easy replacement it is recommended that each transducer has its own
steel conduit.
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 diameter
: 35 mm
•
Wall thickness
:
– Galvanized: 4.5 mm
– Not galvanized: 6 mm
