Application Summary AI generated
This standard specifies the technical requirements, test methods, and inspection rules for high-frequency symmetrical telecommunication cables with copper conductor star quads and a lead sheath. It is applied in the manufacturing and quality verification of cables used for long-distance carrier communication systems, such as trunk lines in telecommunication networks operating at frequencies up to 252 kHz. The standard ensures reliable signal transmission in environments requiring lead-sheathed protection against moisture and mechanical stress.
