Frayed cables can be highly dangerous. If they are weight bearing cables, the fray can cause a loss of integrity and failure of the cable. The fray itself can cause punctures and lacerations. If the cable is carrying any charge, the fray can result in a failure of the insulation and possible electric shock.
-- galvanized steel cable -- dyed silk cable -- fiber-optic cable
To negate creating a uniform magnetic field from the cable.
The electric cooker cable is made thicker because it has to carry more current. If it were too thin it would heat up and perhaps melt.
Waveguides are used at higher frequencies where their loss is lower than coaxial cable. Coaxial cable is used at lower frequencies where waveguides are too large and heavy. Lastly Coaxial cable is also used at higher frequencies where some flexibility is required.
Gutta Percha is a flexible rubber-like material. It was used as an outside coating for the first transatlantic telegraph cable.
Armored cable that has a inbedded tape that is used for grounding purposes. The steel tape is wrapped around the inner conductors which carry the load current. A heavy rubber coating is applied over the steel tape layer. The steel and heavy rubber helps protect the cable from physical damage, e.g. by someone digging in the ground where the cable is buried.
The cable is not the problem the protective coating on the cable is. MilSpec cable is very hard to burn the cable, normal cable coatings when burned give off toxic gases depending on what the coating is made of.
IF THE CABLE IS DAMAGED, THE HOUSING IS DAMAGED. ITS A COMMON PROBLEM. REPLACE WITH NEW PARTS
Bare cable is simply a conductor without a coating, sheating, or covering. It is just bare wire.
I had a stuck throttle on my 1996 Passport. The throttle cable had a piece of protective black rubber around the throttle cable between the outer cable covering and where the cable connects to the throttle body. The rubber had began to come apart and some of it was getting inside the throttle cable covering, causing the throttle cable to bind. I removed the rubber piece and cleaned out the cable by covering it with GOOF-OFF and then sliding the cable in and out until my cleaning rag was clean when I wiped off the cable. I did not replace the rubber piece and have had no problems since.
ethylene propylene rubber (EPR)
The cable must be replaced if damaged.
That depends on what temperature-rise you'll accept, and on what type of coating or jacketing surrounds the cable, and on the airflow around the cable.
no power . cable damaged or unplugged
it worked by using rubber bands and light bulbs, mostly rubber bands, that's why
Duct tape is nonconductive, and is not CAT6. If you have a damaged CAT6 cable, you could put duct tape over the damaged area, but there is no guaruntee the damage won't cause the cable to underperform (your network may not work at 1Ghz).
