Damp-proof corrosion-resistant inflaming-retarding electric power communication cable

Abstract

The invention discloses a damp-proof corrosion-resistant inflaming-retarding electric power communication cable which comprises a conductor and an insulating layer. A plurality of cable cores are arranged in the conductor which is arranged in a PVC plastic connecting rod, and a gap between the PVC plastic connecting rod and the conductor is filled with a waterproof filling layer; aluminum alloy hoses are arranged at the center of the PVC plastic connecting rod, and the insulating layer wraps the PVC plastic connecting rod in an extruding mode; a gap between the insulating layer and the PVC plastic connecting rod is filled with fillings; a shielding layer tightly wraps the insulating layer in an extruding mode; a reinforcement layer, a stainless steel armor layer and an aluminum-polythene adhesive protection layer sequentially tightly wrap the shielding layer in an extruding mode from inside to outside; an aluminum alloy interlocked armor barrier layer wraps the aluminum-polythene adhesive protection layer in an extruding mode; a plurality of current guide cores are evenly arranged in the aluminum alloy interlocked armor barrier layer; an inner sheath and an outer sheath are sequentially arranged outside the aluminum alloy interlocked armor barrier layer. The damp-proof corrosion-resistant inflaming-retarding electric power communication cable has the advantages of being good in damp-proof effect, good in corrosion resistance, long in service life, and the like.

Description

technical field [0001] The invention relates to the field of cables, in particular to a moisture-proof, corrosion-resistant, flame-retardant power communication cable. Background technique [0002] At present, with the development of science and technology, people have more and more demands on cables. Cables are a common data signal transmission equipment, which have the advantages of large communication capacity, high transmission stability and good confidentiality performance. However, the existing Some common polymers are used in the cable protective layer, which not only has a short service life, but also pollutes the environment. The Chinese patent document application number is CN201310033225.2, a new type of fluoroplastic insulated high temperature resistant power cable, which is made of conductor , refractory mica layer, insulating layer, shielding layer and outer sheath, and the inside of the cable is equipped with a flame retardant layer wound with glass fiber tape...
