Environment-friendly comprehensively protected electronic computer shielded cable

Abstract

The invention discloses an environment-friendly comprehensively protected electronic computer shielded cable, which comprises conductors, the conductors are wrapped by insulating layers, flame-retardant material is filled to form round cross sections after the conductors wrapped by the insulating layers are arranged in pairs, flame-retardant tape layers are wound on the round cross sections, and are wrapped by single-phase shielding layers, flame-retardant tape layers are then wound on the single-phase shielding layers, so that a plurality of conducting monomers are formed, flame-retardant material is filled to form a round cross section after the conducting monomers are combined, a flame-retardant tape layer is wound on the round cross section, and is wrapped by a main shielding layer, a flame-retardant tape layer is wound on the main shielding layer, and an internal sheath layer, a steel tape armor layer and an external sheath layer are sequentially arranged outside the flame-retardant tape layer. The environment-friendly comprehensively protected electronic computer shielded cable has the following advantages: the environment-friendly comprehensively protected electronic computer shielded cable has the characteristics of environment-friendliness and no public hazards; not only can termite and mouse resistance be enhanced, but also the resistance of the sheath of the cable to mechanical damage, environmental stress and the like is enhanced; the flame-retardant property of the environment-friendly comprehensively protected electronic computer shielded cable reaches class A.

Description

technical field [0001] The present invention relates to the technical field of cables, more specifically to the technical field of electronic computer shielded cables. Background technique [0002] Electronic and computer shielded cables with a rated voltage of 300 / 500V and below are mainly used in metallurgy, electric power, petrochemical and other industrial and mining enterprises for distribution systems, electronic computer systems, and automation systems. Places with high anti-interference performance requirements. However, the current common electronic computer shielded cables are helpless to the damage of termites and mice to the cables. Termites and mice have strong ability to survive and reproduce, and they are widely distributed. With the continuous development of social economy, cables are laid more and more densely, so the probability of cable damage is increasing; High voltage, high capacity and integrated development, once destroyed by termites and rats, will...
