Abstract

The utility model provides a take compound flat cable of three -core on shock insulation layer, including from inside to outside in proper order around the power cable core of package, around covering, control core and sheath, the power cable core includes two looks sinle silks that directly drag side by side, and the looks sinle silk becomes flat parallel configuration outward has a plurality of softening springs, control core becomes flat parallel configuration outside the power cable core. The utility model discloses a shock insulation protection is carried out to the sinle silk in softening spring and woven wire layer, can effectively improve the life of cable in earthquake multiple area.

Description

A kind of three core composite flat cables with Seismic Isolation of Isolation Layer

Technical field

This utility model relates to power cable field, specifically a kind of three core composite flat cables with Seismic Isolation of Isolation Layer.

Background technology

Along with popularizing of computer technology and developing rapidly of information industry, Intellectual district has become the development trend of modern architecture, by the comprehensive wiring system that is made up of composite cable etc. the communication in intelligent construction, computer and various equipment and facility, include comprehensive wiring system under certain conditions in, it is interconnected to form completely supporting entirety, to realize highly intelligentized requirement.

For earthquake prone areas, the cable being embedded in underground is given a shock for a long time, it is easy to break down, and existing cable lacks corresponding isolation measure.

Utility model content

This utility model is the shortcoming overcoming prior art to exist, it is provided that a kind of safe and reliable, isolating affection is good, the three core composite flat cables with Seismic Isolation of Isolation Layer of long service life.

This utility model includes wrapped successively from inside to outside power cable core, lapping layer, control conductor and sheath, it is characterised in that: described power cable core includes two phase cores directly dragged side by side, becomes flat laid out in parallel to have some slinky springs outside phase core；Control conductor becomes flat laid out in parallel outside power cable core.

Improve further, the equidistant gap arrangement of described slinky spring or to be covered with phase core peripheral, identical with the filament diameter size of phase line core conductor.

Improve further, the equidistant gap arrangement of described control conductor or to be covered with power cable core peripheral.

Improving further, described lapping layer is oven wire mesh blanket.

Improving further, described phase core is the some solid naked round conductors extruded or the some filled circles conductors extruding insulation.

This utility model has the beneficial effects that: by slinky spring and oven wire mesh blanket, core is carried out shock insulation protection, can be effectively improved the service life of cable in the area that earthquake is multiple.

Accompanying drawing explanation

Fig. 1 is this utility model structural representation.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

This utility model includes wrapped successively from inside to outside power cable core, lapping layer 5, control conductor 2 and sheath 3, and described power cable core includes two phase cores 1 directly dragged side by side, phase core 1 outer become flat laid out in parallel have some slinky springs 4；The equidistant gap arrangement of slinky spring 4 or to be covered with phase core 1 peripheral is identical with the filament diameter size of phase core 1 conductor.Power cable core is wrapped by lapping layer 5, the equidistant gap arrangement of control conductor 2 one-tenth flat or to be covered with power cable core peripheral.Described lapping layer 5 is oven wire mesh blanket.Described phase core is the some solid naked round conductors extruded or the some filled circles conductors extruding insulation.

The concrete application approach of this utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model principle; can also making some improvement, these improvement also should be regarded as protection domain of the present utility model.
