A weak electrical cable is a cable used for security communications, electrical equipment, and related weak electrical transmissions.
Wire and cable refers to materials used in power, communications, and related transmission applications. There are no strict boundaries between "wires" and "cables." Generally, a product with a small number of cores, a small product diameter, and a simple structure is called a wire, a non-insulated wire is called a bare wire, and the other is called a cable; a conductor having a large cross-sectional area (greater than 6 square millimeters) is called a large wire. Small (less than or equal to 6 square millimeters) is called a small wire, and insulated wire is also called a wire.
Wire and cable mainly includes bare wires, electromagnetic wires and insulated wires for electrical appliances, power cables, communication cables and optical cables.
It consists of an inner conductor, an insulation, an outer conductor and a sheath from the inside out;
Inner conductor: Since the attenuation is mainly caused by the resistance of the inner conductor, the inner conductor has a great influence on the signal transmission.
Insulation: affects attenuation, resistance, return loss and other properties
Outer conductor: return conductor, shielding
