[PSUBS-MAILIST] data cable

[hank pronk via Personal_Submersibles]

 Alan, I have tested my penetrators with no additional glue or silicone.  I agree silicone or glue is a good idea but in testing I have discovered that it takes 1,000 psi before air will pass between the wire shield and up the wire.  I tested be screwing the penetrator into a pipe.  I pressurized the pipe interior with air not water.  I then place the pipe in a bucket of water to look for bubbles.  Not until 1,000 psi will very minor random air bubbles appear.  If the test was reversed with water in the pipe then I suspect it would take much more pressure to push water past.  Hank

 Brian,I cover the insulation on the wires & the potting material with a PVC glueup to an inch from where it is potted. I use a 2 pot heat activated PVC gluethat will tear the PVC before it peals off.Reason for this is water can force down between the PVC & the potting material.Alan

 Brian, it the strands are solid core, you can strip off the insulation and then pot.  If the strands are multi wire then cut and sold in a section of solid wire to pot.Hank

 Hi All,            What would be the best way for me to pot a cat5 ethernet cable?    Would the insulation need to be removed?
