PVC Insulated Wire and several more options available
PVC is an excellent material for wire insulation. Insulation separates conductors, electrically and physically, within a cable. Capacitance is a measure of the insulation’s ability to store electrical energy. The measurement is expressed in picofarads per foot and compounded linearly with length. In choosing wire for your specific application, think about these physical considerations: elongation, tensile strength, temperature rating, flexibility, flammability, resistance, and specific gravity.
