U/S power cable length

I have a project which needs to use long cables. The length is about 60 feet. A few cables to be prepared: U/S cable to transducer and interface cables to handling unit. I think the interface cable is not an issue since they are generally digital signal. I am not sure if the what is the maximum U/S cable length. Anyone can help?

Questions:
1. Is the U/S cable length an important? What are the effects?
2. If I want to use long U/S power cable, what should I do?

Thank you.

Hi SohKL,

There are certainly potential problems from using a long cable between generator and transducer if the electrical properties of the cable (I guess particularly capacitance) become significant in relation to the properties of the transducer.

I think up to 10 or 20 feet isn't normally a problem (at least at 20kHz). You might still be ok at 60 feet but in any case the manufacturer may be able to adjust their control system to cope. Can you ask your supplier for recommendations?

If not, well, I keep hoping someone better qualified than me might stop in here to answer difficult questions like this!

Hi, Chris.

We are trying at this length to make sure that the weld is still fine. Actual length to use is just about 30~40 feet.

After trying the 60 feet cable, the weld is OK. Might need to do more work to ensure the weld quality is maintained.

Thank you for your reply.

Regards.
