Abstract
The utility model discloses a shield cable used by a digital data logger, comprising a plurality of conductors. Insulating layers are respectively extruded at outer sides of the conductors; taped coverings are wrapped on outer sides of the insulating layers; a plurality of fillers are respectively arranged between the taped coverings and the insulating layers and between the insulating layers of the conductors; the fillers are ropes with triangular cross sections made of stranded water resistance belts; inner shield layers and outer shield layers are successively wrapped on the outer sides of the insulating layers; and sheath layers are extruded outside the outer shield layers. According to the utility model, a plurality of fillers are respectively arranged between the taped coverings and the insulating layers and between the insulating layers of the conductors; materials of the fillers are water resistance belts; on one hand, water resistance performance of a cable is effectively increased; the structure of the cable is compact; and service lifetime is prolonged.
Description
Technical field:
The utility model relates to the shielded type cable field, relates in particular to a kind of digital data-logger and uses shielded type cable.
Background technology:
China's economic growth continuously and healthily; For cable products provides the huge market space, the temptation that Chinese market is strong makes the world all focus on Chinese market to sight; Reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry lets the world regard with special esteem.Along with the continuous expansion of industry sizes such as China Power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.
For existing digital data-logger shielded type cable, more loosening between several conductors behind the cable bunchy, structure is compact inadequately, and the humidity resistance of cable is relatively poor simultaneously, can not satisfy the demand of actual environment.The utility model is filled out core material and is adopted waterstop between lapping layer and the insulating barrier, be respectively equipped with several cores of filling out between the insulating barrier of several conductors, has solved the problems referred to above effectively.
The utility model content:
To the prior art problem; The purpose of the utility model provides a kind of digital data-logger and uses shielded type cable, is used for ac rated voltage 450/750kv and following instrument is used the control cable product, and interference free performance is superior; The water resistance of cable is superior, compact conformation.
The technical scheme of the utility model is following:
The numeral data-logger is used shielded type cable; Comprise several conductors, it is characterized in that: several conductors outside is extruded with insulating barrier respectively, and the insulating barrier outside is enclosed with lapping layer; Between lapping layer and the insulating barrier, be respectively equipped with several cores of filling out between the insulating barrier of several conductors; Several fill out core be waterstop to be twisted into the cross section be leg-of-mutton rope, the described insulating barrier outside is enclosed with internal shield, outer shielding layer successively, outer shielding layer is extruded with restrictive coating outward.
Described digital data-logger is used shielded type cable, it is characterized in that: described internal shield adopts the wrapped formation of aluminium-plastic tape, and described outer shielding layer adopts the tin plated steel wire braiding to constitute.
Described digital data-logger is used shielded type cable, it is characterized in that: described several conductors adopt the stranded bunchy of tinned copper wire to constitute, and the tinned copper wire filament diameter is 0.2-0.6mm.
The utility model has the advantages that:
The utility model is filled out core material and is adopted waterstop between lapping layer and the insulating barrier, be respectively equipped with several cores of filling out between the insulating barrier of several conductors, and the water resistance of cable has obtained effective lifting on the one hand, the compact conformation of cable simultaneously, and prolong useful life.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
The numeral data-logger is used shielded type cable, comprises several conductors 1, and several conductors 1 outside is extruded with insulating barrier 2 respectively; Insulating barrier 2 outsides are enclosed with lapping layer 3, and between lapping layer 3 and the insulating barrier 2, be respectively equipped with several cores 4 of filling out between the insulating barrier 2 of several conductor 1, several cores 4 of filling out are leg-of-mutton rope for waterstop is twisted into the cross section; The water resistance of cable has obtained effective lifting on the one hand; The compact conformation of while cable, insulating barrier 2 outsides are enclosed with internal shield 5, outer shielding layer 6 successively, the outer shielding layer 6 outer restrictive coatings 7 that are extruded with; Internal shield 5 adopts the wrapped formation of aluminium-plastic tape; Outer shielding layer 6 adopts the tin plated steel wire braiding to constitute, and several conductors 1 adopt the stranded bunchy of tinned copper wire to constitute, and the tinned copper wire filament diameter is 0.2-0.6mm.
