Armored cable

Abstract

The invention relates to an armored cable. The armored cable comprises optical fiber copper wire cables, insulation paper arranged outside the optical fiber copper wire cables, and a steel belt armorlayer which wraps the insulation paper. The armored cable has high mechanical strength and corrosion resistance and a good protection effect on cables in outdoor severe environment operation, and is simple in structure and easy to produce and popularize.

Description

technical field [0001] The invention relates to a cable, in particular to an armored cable. Background technique [0002] When ordinary cables, especially telephone cables, are laid in areas that are vulnerable to mechanical damage and corrosion, the safety of use will be affected to a certain extent. Armored cables are often used to improve their strength. However, in some harsh environments, it is usually accompanied by corrosive agents, which pose a threat to the safety of armored cables. Contents of the invention [0003] Purpose of the invention: Aiming at the deficiencies in the prior art, the purpose of the invention is to provide a corrosion-resistant armored cable. [0004] Technical solution: an armored cable, including an optical fiber copper wire cable, an insulating paper arranged outside the optical fiber copper wire cable, and a steel tape armor layer covering the insulating paper. [0005] The insulating paper is oil-impregnated insulating paper. [00...
