Scope

This section is used together with GB/T 18015.1. This cable is dedicated to the horizontal layer wiring defined in GB/T 18233. This standard applies to cables with fewer than 20 pairs or 10 quads for horizontal layer wiring. Twisted pairs or quads are available with or without individual shielding. The cores of such cables may have an overall screen. This tariff applies to the various communication systems mentioned in the appropriate detail specification. The electricity charges included in this section shall be operated at the voltage and current normally used in the communication system. These electricity bills should not be connected to a low-impedance source such as the public supply. Recommended temperature ranges during installation and operation are specified in the detail specification.
