1 Scope

GB/T 18015 provisions of this section 1200MHz and below transmission characteristics of twisted pair or twisted symmetrical cable installation conditions, timber Materials and Cable Structure, Performance and Requirements.

This section applies to a variety of communication systems and existing or developing analog systems, such as video systems used in the cable up to Four pairs of cables can be used at the same time. The structure of the cable is 4 pairs of separate shield pairs, which can be covered by the outer shield.

Note The cables specified in this standard apply to the voltage and current specified in the communication system and should not be used on low impedance power supplies such as public power supply systems.

This section GB/T 18015.1-2017 together with the use.
