Insulating transducer cable from other power.

[jeffo]

Hi all,

I know it is not ideal to be running my transducer cable with the rest of my cables and power, but unless i run the cable across the floor of the boat i dont have any other option.

My question is how can i best insulate the trandsuder cable from the rest of the cables to minimise interference from outside power.

Is there a special insulating conduit (flexible) that i could use or will 2 layers of the black corrogated split loom do the job?

Any help would be much appreciated.

Cheers.

Hey Jeffo,

I use to always run my transducer cable down the opposite side to all the wiring but on the new boat ask John Eadie who did my wiring fitout his thoughts and he said with the good insulated wiring now there would be no issue. I took his advice and I have no issues and believe I get next to no interference.

Cheers

G'day Jeffo,

Most cable sthese days are triple or quad shielded ... therefore the interference problem is not really an issue.

Make sure all wiring is good and connections are sound and you will be fine.

Just consider this ... every flybridge boat thatI wire up has the (usually 1kw) transducer running up beside the motor, genset, battery charger and all battery banks ... up through a conduit where it meets all the 12v and 240v distribution panels ... up through another conduit with all these wires jam packed into them to get to the flybridge.
Then weave your way through the other electronics flush mounted in the dash ... meet up with the radar and GPS cable, then into the unit.

We manage to do all of this and still get top performance from the unit, so you should be quite ok.

What units are you installing?

Cheers,

Pete

thanks guys, the cause of my bit of interference may be related to the trandsucer location rather than a power surge. I will play with that and see how i go.

Pete- dolphin boating world had a few navmans at a good price. I got a 4507 (600w, dual freq) for 300 bucks less than the usual going rate. Wouldnt normally have been my first choice but at the price it was in my budget, and was colour.

Insulation realy isn't the issue. You are probaly more worried about inductive or electrostatic coupling.

Any way the only thing that should cause any interfeerance is lines running to motors or the like...any steady state current draw items like lights should have no effect whatsoever.

Apart from completly enclosing in a steel conduit the only thing that will improve induced coupling will be distance, and the standard provided shielding should be fine to cover the electrostatic.

It occurs to me that this might be one of those over stated, issued in marine electronics......If you can run the cable with good sepeartion without trouble you would be silly not to......but dont sweat it otherwise....unless you have a problem.

In truth the quality of your electrical connections ( particularly the common earth and supply points) and the weight of your power wires is more likley to make a difference.

cheers
