Modern Electronic cables come in a variety of sizes, materials, and types, each particularly adapted to its uses. Cables consist of three major components, namely conductors, insulations, protection. The constructional detail of individual cables will vary according to their application. The construction and material are determined by three main factors:
Working voltage, which determines the thickness and composition of the insulation;
Current carrying capacity, which determines the cross-section size of the conductors;
Environmental conditions such as temperature, chemical or sunlight exposure, and mechanical impact, which determines the form and composition of the cable jacket enclosing conductors.
Electronic cables can vary from predominately static to flexible applications and the copper conductors can vary from tinned or bare copper conductors both in solid or stranded wire.  Other electrical characteristics will come into play if being used in certain applications, such as capacitance, impedance, and attenuation requirements.
