Shielded Cable

what kind of wire has a core and then a coating and then another set of wires and another coating?

i was trying to fix my fm transmitter for my truck and i noticed one of the wires inside it had a core of wires and then a coating, and then outside the coating is another bunch of bare wires wrapped around it flat and then another coating. what kind of wire is this i cant seem to figure out what it is? can you help me?

That is a shielded cable or coaxial cable. It is used for a lot of signal transmission as the shield, the outside conductor, completely encloses the center conductor. When the shield is grounded, it prevents any outside interference from getting to the signal, which is carried on the center conductor.

In addition, for RF, the shield and the center conductor present a constant impedance (usually 50 or 75 ohms) where the capacitance and the inductance cancel out, and allow power to be transmitted along the cable with only small losses.

The coax cable will probably have a number printed on it, such as RG58. Use that to buy replacement cable. Or cut off a piece and take it to the store. Note that attaching connectors to the ends of the cable take special tools and a lot of practice. Try to get a cable with the connectors already attached.
