insulated cables for power signals

[bhatti]

Hello all

we are using audio power amplifiers which delivers around 2000 watt signal to the transducers having input impedance of approx 150 oham. The signal at output of power amplifier is of sinusoidal type with approx. 600 Vrms. The current drawn by the load (transducer) is approx 3.2A. Our frequency of intrest is 2 - 5 KHz

Problem is that we need to place multiple of 900m length cables b/w power amplifiers and transducers.Each power amplifier drives single transducer. These cables needed to be placed very close to each other so some insulation is required so that signal in one pair of cable does not effect the signal in other pair (i.e. no cross talk, phase distortion etc)

Please help us to select  any commercially available insulated cable satisfying above requirements.Any kind of help is much appreciated

THANKS

Insulation does not prevent crosstalk. A shield (coaxial cable) reduces crosstalk.
