Polyethylene – A thermoplastic content having superb electrical Attributes. Minimal dielectric frequent, a secure dielectric continuous around all frequencies, quite superior insulation resistance.
Defend Success – The relative potential of the defend to screen out undesirable interference. Frequently confused While using the time period protect protection.
Reactance – A measure on the merged outcomes of capacitance and inductance on an alternating present-day. The amount of these types of opposition differs with the frequency of the present. The reactance of the capacitor decreases with an increase in frequency; the opposite happens having an inductance.
Rated Temperature – The utmost temperature at which an electric ingredient can function for prolonged periods without lack of its essential properties.
Optical fiber carries Considerably more info than common copper wire and is mostly not subject to interference. Most telephone company extensive-distance strains are optical fiber.
Reference Edge – Fringe of cable or conductor from which measurements are made. At times indicated by a thread, identification stripe, or printing. Conductors tend to be identified by their sequential posture from your reference edge, with number one conductor closest to this edge.
Capacitive Reactance – The opposition to alternating present due to capacitance weblink of the capacitor, cable, or circuit. It is measured in ohms and it is equivalent to 1/6.28fC exactly where f could be the frequency in Hz and C is definitely the capacitance in farads.
Braid – A bunch of textile or metallic filaments interwoven to kind a tubular flexible construction which can be applied above a number of wires, or flattened to sort a strap.
