Abstract

The utility model discloses a resistant oily polyvinyl chloride insulation shielding cable, it includes a plurality of cable cores, be equipped with the combination conductor in the cable core, the combination conductor has covered semiconductor layer in proper order, insulating cover of shielding and insulating inner core, the cable core separates through the median and outside parcel has pottery fluorubber insulating layer, the cable core, the packing layer of blocking water has between median and the pottery fluorubber insulating layer, pottery fluorubber insulating layer outside parcel has the internal shield layer, internal shield layer outside parcel has the external shielding layer, the external shielding layer outside is wrapped up the glass fiber layer and is wound the package inner liner, wrap up armor and butyronitrile polyvinyl chloride protective sheath in proper order outside the package inner liner. The utility model discloses can to a great extent the shielding of reinforcing cable, increaseed the tensile ability of cable, avoid the cable protection layer to cross the outbreak damage because of local atress, can let the many environment of cable adaptation oil, improved the life of cable greatly.

Description

A kind of oil-resistant polyvinyl chloride insulation shielding cable

Technical field

This utility model relates to a kind of oil-resistant polyvinyl chloride insulation shielding cable.

Background technology

Cable is usually used in Urban Underground electrical network, the lead line of electric station, the in-line power of industrial and mining establishment and crosses the submarine transmission line in river, excessively sea.Cable easily meet with in erection process pull and roll over around, it is easily caused erection inconvenience and frangibility in the case of cable is too hard, simultaneously easily meet oil and chemical reagent when the place that environment is more severe uses and be corroded, thus cause service life of cable limited.

Utility model content

The defect existed for above-mentioned background technology, this utility model provides a kind of oil-resistant polyvinyl chloride insulation shielding cable.

For achieving the above object, the technical solution adopted in the utility model is: it includes multiple cable core, combined conductor it is provided with in cable core, combined conductor is coated with semiconductor layer successively, shielding insulation set and insulation inner core, cable core carries out separating by isolation strip and outside is enclosed with ceramic fluorubber insulating barrier, cable core, between isolation strip and ceramic fluorubber insulating barrier, there is water blocking filler layer, it is enclosed with internal shield outside ceramic fluorubber insulating barrier, external shielding layer it is enclosed with outside internal shield, glass layer and wrapping lining-layer is wrapped up outside external shielding layer, armor and butyronitrile polrvinyl chloride protection set is wrapped up successively outside wrapping lining-layer, it is additionally provided with one layer of malthoid layer between armor and butyronitrile polrvinyl chloride protection set.

This utility model has the advantages that this utility model capacity of resisting disturbance is strong; by multilayer screen layer; can largely strengthen the shielding of cable; increase the resistance to tension of cable; avoid cable covering, because local pressure is excessive, breakage occurs; cable can be allowed to adapt to the environment that oil is many, expand the range of cable, substantially increase the service life of cable.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.

As shown in Figure 1, this utility model includes multiple cable core 1, combined conductor 2 it is provided with in cable core 1, combined conductor 2 is coated with semiconductor layer 3 successively, shielding insulation set 4 and insulation inner core 5, cable core 1 carries out separating by isolation strip 7 and outside is enclosed with ceramic fluorubber insulating barrier 8, cable core 1, between isolation strip 7 and ceramic fluorubber insulating barrier 8, there is water blocking filler layer 6, it is enclosed with internal shield 9 outside ceramic fluorubber insulating barrier 8, external shielding layer 10 it is enclosed with outside internal shield 9, glass layer 11 and wrapping lining-layer 12 it is enclosed with outside external shielding layer 10, armor 13 and butyronitrile polrvinyl chloride protection set 15 is wrapped up successively outside wrapping lining-layer 12, it is additionally provided with one layer of malthoid layer 14 between armor 13 and butyronitrile polrvinyl chloride protection set 15.By multilayer screen layer, can largely strengthen the shielding of cable, increase the resistance to tension of cable; avoid cable covering, because local pressure is excessive, breakage occurs; cable can be allowed to adapt to the environment that oil is many, expand the range of cable, substantially increase the service life of cable.

The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
