Abstract

The utility model discloses a power-and-monitoring combined cable. The power-and-monitoring combined cable comprises a plurality of power line core conductors, an earth wire core conductor and a monitoring line core conductor, wherein the outside of each power line core conductors are sequentially coated with a silicone rubber insulating layer and an insulating shielding layer so as to form a power insulating line core; the outside of the earth wire core conductor is sequentially coated with a crosslinked polyethylene insulating layer and a thermoplastic elastomer in a plastic extrusion manner so as to form an insulating earth wire core; the outside of the monitoring line core conductor is coated with a fluoroplastic insulating layer so as to form an insulating monitoring line core; the power insulating line cores and the insulating monitoring line core are twisted into a strand taking the insulating earth wire core as a center so as to form a combined cable core; the outside of the combined cable core is sequentially coated with composite isolating layers; and an outer sheath layer is molded outside the composite isolating layers in a plastic extrusion manner. The power-and-monitoring combined cable reasonably combines the power line core conductors and the monitoring line core, increases multiple functions of the cable, has sound anti-extrusion performance and isolation effects, and has prolonged service life, thereby facilitating cable installation and cable laying.

Description

A kind of power and supervision combination cable

Technical field:

The utility model relates to combination cable, relates in particular to a kind of power and monitors combination cable.

Background technology:

Shortcomings such as traditional cable has function singleness, and performance is low, such as monitoring cable when the cable that needs several functions, just needs the mounting and installation multi-cable, has caused a lot of inconvenience, in addition, the anti-extrusion performance of cable, isolation effect are poor.

How with the cable combination of multiple different purposes together, the combination of practical function, transmission brings certain practicality to information.
