What is the specific meaning of communication cable transmission parameters?

Communication cable transmission parameters include:

1. Effective resistance: The effective resistance of the cable circuit, including DC resistance and additional resistance (ac) through alternating current.

2. Inductance: In the communication cable circuit, the magnetic flux current caused by the ratio of the magnetic flux is called the inductance.

3. Capacitor: The cable circuit concept of a capacitor is similar to that of a general capacitor. The conductor surface is equivalent to a capacitor plate, and the wire insulation is equivalent to a dielectric capacitor. Its value is the ratio of the electrical conductor to the potential difference between the two conductors.

4. Insulation conductance: Insulation conductance indicates the insulation quality of the circuit. Insulation conductance is generally divided into two parts: DC conductance and AC conductance. The former is caused by the imperfect insulation of the cable medium, and the latter is caused by the polarization effect of the medium. Insulation conducts moderate heat, resulting in energy loss.
