Multipair Cable Prep at Wall Plate

Post by jeffpiano »

Hi there: This is Jeff in Mesa Arizona USA. Just joined forum. I've been asked to correct some wiring in a studio being constructed. Mutipair snakes from the control room are run separately to an isolation booth and to the main studio. The snake is from Conquest, mfd by Gepco (wouldn't have been my choice). Each channel is foil shielded, not individually jacketed, (I'd prefer they were jacketed). The outer jacket of the snake is removed back about 18", exposing 40 pr. of foil shields, some of which have unraveled. My inclination is to unterminate all the channels, rewrap the foil on each channel, secure it with tape if necessary, slide a large diameter piece of shrink over the outsdie jacket of the snake to act as a collar, slide narrower heat shrink tubes over each individual channel, leaving an inch or so of the conductors to be stripped for soldering, slide an individual piece of clear spaghetti over the last inch or so of the drain. This way, the drains are jacketed, the foil shields don't unravel or contact one another.

This is very time consuming. I mentioned that the cable should have been individually jacketed multipair in the 1st place.

Am I committing overkill? I am a believer in keeping shields and drains intact and individualized as much as possible. The studio owner thinks I'm too concerned. (His studio builder also used hardare store grade light dimmers, and is surprised that there's a buzz in the system!)

What would you suggest as the best way to prep and terminate these cables? WHen would someone want to use multipair cables with channels that are only foil shielded, not jacketed?

Any help is greatly appreciated.

Thanks

JEff
