Types of Copper Cables

Solid Wire:

Single strand copper wire is also called solid wire (solid core wire), consists of one piece of copper wire surrounded by an insulating material.

Cable:

All Copper Cables consists of two or more wires bounded and twisted together, running parallel to each other, forming a single assembly.

Types:

There are many Types of cable. such as

1. Shielding cable

2. Coaxial Cable

3. Strip Cable

4. Twisted pair Cables

           i) U/UTP

           ii) S/UTP

          iii) U/STP

          iv) S/STP

1. Shielding cables

Shielding cables are enclosed in wire mesh (Foil). The wires inside the shielding are mostly isolated from external electric fields.

2. Twisted pair cables

Twisted pair cable consists of two wire conductors that are twisted together as shown in fig. This phenomena is used to cancel out the electromagnetic interference (EMI) from external signal. which in turn reduces the loss of signal. There for twisted pair cables are being used in communication field from many decades, for conversions on telephone.

3. Coaxial cables

Coaxial cable is constructed by two or more wires or conductors that are centrally wrapped, and are separated by a dielectric (insulator). One solid conductor is in the center of cable, while other hollow conductor or wire is surrounding the Central conductor and the medium between them is (Polyethylene (PE), Polypropylene (PP), Fluorinated Ethylene Propylene (FEP) or Poly Tetra Fluoro Ethylene (PTFE)) used as insulator.
This concentric cylindrical form causes voltages induced by a magnetic field between the shield and the core conductor, nearly equal magnitudes which cancel out each other and reduces the signal losses.
Main advantage of Coaxial cable is that is has very little influence of interference on the carried signal from the outside. using interference to signals inside the cable. This property makes coaxial cable a good choice for carrying weak signals that cannot tolerate interference from the environment or for higher power signals that must not be allowed to radiate or couple into adjacent structures or circuits Coaxial cables, reduce low-frequency magnetic transmission and pickup.
