So, again some cut cables, this time with the twist that i don't have the option of replacing this one. It needs to be spliced back together
The cable in question is a 20KV shielded high voltage cable powering a CRT. Since the cable i in a potted tank on one end, and an incline resistor on the other (with the anode cap for the CRT) i cant exactly replace it.
So, here is what i was thinking about doing:
Remove the outer insulation and shielding braid from about 3 cm of wire per side. Remove the inner insulation from about 5 mm on each side. Solder together.
Then using custom made PVC or Nylon Cylinders with a hollow cavity and hole, cover the solder joint, making sure shielding is not within this joint. Then fill this cylinder with Epoxy. Then once that is cured, place braided shielding over the joint, and connect to the original shielding (the cable is not RF, so i think i can probably get away with just a wire here). Then using 3:1 sweatshirt cover the joint.
So, before i go run off and make this, will this work?
I have the ability to test this up to 50KV AC if need by, but i would like your guys input on this before i set up my HV test system, and make a few test cables.
If anyone is wondering, this cable already has a splice on it, to accommodate the current limiting resistor installed by the OEM. So, i know its possible to do, i just haven't found an off the shelf product to do it.
Any input and or help would be much appreciated.
If anyone wants pictures of the cable in question, i would be happy to post some.
