Abstract

The utility model relates to a median ground-wire composite cable, which is characterized in that the cable comprises a phase conductor (1), an insulating material layer (2), three median lines (7), ten control line cores (3), a drainage line (5) and an outer sheath layer (6), wherein the phase conductor (1) is positioned in the center of the cable; the insulating material layer (2) is wrapped outside the phase conductor; the three median lines (7) and the ten control line cores (3) are arranged around the insulating material layer; the ten control line cores (3) are wrapped with insulating material layers (4); the drainage line (5) is wound outside the median line and the control line core in a form of helical distant winding and can prevent mutual interference; and the outer sheath layer (6) is wrapped outside the drainage line. The composite cable can combine the cables in different applications together, namely, the structures of a cable used for apparatus control and a cable used for apparatus grounding are designed, therefore, the cables are not affected mutually; the cables are combined into one cable to realize multifunctional transmission, so as to bring convenience for realizing safe grounding protection and transmitting control signals for apparatuses and equipment, thereby not only effectively lowering the cable production cost and the cable laying cost, but also saving larger laying space.

Description

Ground wire composite cable in a kind of

Technical field

The utility model relates to a kind of cable, relates to a kind of middle ground wire composite cable that integrates phase conductor, control core, neutrality line, drainage thread specifically.

Background technology

Traditional cable mostly is the cable of special purpose, and promptly a cable only possesses a kind of purposes.Realize that various supplies just must lay many cables and finish.This also just will inevitably cause the increase of its overall investment (cables manufacturing, lay expense), and also need take the bigger space of laying.

Summary of the invention

The purpose of this utility model is just at existing weak point in the above-mentioned prior art, and a kind of middle ground wire composite cable that integrates phase conductor, control core, neutrality line, drainage thread is provided.

The purpose of this utility model can realize by following technique measures:

The ground wire composite cable comprises the stranded thread phase conductor of the employing that is positioned at cable center, is wrapped in the outer insulation material layer of phase conductor in of the present utility model, the control core, the spiral that all are enclosed with insulation material layer around the many neutrality lines and the Duo Gen of insulation material layer setting dredge around the mode of (twining as the yellow spiral of bullet) and twine neutrality line and control drainage thread outside the core, be wrapped in the external sheath layer outside the drainage thread.

Neutrality line described in the utility model is real core conductor structure, and its quantity is: 3～7.Described control core quantity is: 4～20.Described phase conductor adopts twisted wire to make

The beneficial effects of the utility model are as follows:

Composite cable of the present utility model with the cable combination of different purposes together, promptly the cable and the earthy cable of facility that are used for facility control are passed through structural design, make it to be independent of each other each other, concentrate on a cable and realize multi-functional transmission, realizing safety ground protection and transmission of control signals for facility, equipment and instrument offers convenience, not only can effectively reduce the cables manufacturing cost and lay expense, and can save the bigger space of laying.
