Technical Field

[0001] The utility model belongs to the technical field of cables, and in particular relates to a heat-resistant self-supporting lightweight multi-core shielded communication cable. Background Art

[0002] Self-supporting multi-core communication cables are mainly installed overhead, with the same outer sheath for the suspension wire and cable, which is economical, practical, and easy to install and lay. However, general communication cables have poor load-bearing capacity and insufficient torsion resistance. During installation, they are prone to core breakage and shielding layer breakage, which affect the electrical characteristics of normal operation. The insulation layer of ordinary communication cables is mostly made of foamed polyethylene or foamed polypropylene resin, which has weak mechanical strength and poor durability.
