Description

Cable

Technical field

This utility model relates to electrical distribution field, particularly relates to a kind of cable.

Background technology

Cable is conductor conventional in people's daily life.Now with socioeconomic development, cable consumption increases rapidly, to the prescription of cable also in continuous raising, the cable such as used in industries such as iron and steel, metallurgy, electric power, chemical industry, oil, has higher requirement to the heat-resisting quantity of cable, capacity of resisting disturbance, pull resistance and service life.

The origin of heat of usual cable is generally divided into two parts, and a part originates from conductor, and a part originates from external environment condition.When electric current is by cable conductor, owing to cable conductor itself has resistance, electric energy some will be converted into heat energy, thus producing heat, makes cable conductor temperature raise, so that cable temperature raises.In order to solve this problem, it is possible to reduce its resistance by the cross-sectional area of increase cable conductor and reduce energy loss and cable temperature.Would not play a role when but the ambient temperature that this method is when cable uses is higher.Cable continues when the external environment condition work that temperature is higher, and the macromolecule being easy for causing insulating barrier and protective layer outside cable conductor is aging, shortens the service life of cable.

Simultaneously cable is often many and uses simultaneously, so cable produces to interfere sometimes.Cable is often dragged when laying or use, so the resistance to tension of cable also affects the service life of cable.

Utility model content

The purpose of this utility model is in that to provide that a kind of resistance to elevated temperatures is good, capacity of resisting disturbance is strong, tensile property is high and the cable of long service life.

For solving above-mentioned technical problem; this utility model provides a kind of cable; this cable includes cable inner core, glass fibre belting layer, external shielding layer, the high temperature resistance diaphragm saw lumber bed of material, wirerope protective layer, PPS layer from inside to outside successively; described cable inner core includes cable conductor, internal shield, insulating barrier and colour band from inside to outside successively; being mica tape packed layer between described cable conductor and internal shield, described insulating barrier is fluororubber layer.

In order to strengthen cable capacity of resisting disturbance, described internal shield and external shielding layer are the wire sheathings worked out by tin plating soft copper band.

In order to strengthen the resistance to tension of cable, the described wire sheathing that wirerope protective layer is braided steel wire.

The beneficial effects of the utility model are: the internal shield of the cable of this utility model can function well as the shield effectiveness between cable core, improves anti-interference, thus decreasing crosstalk；The external shielding layer of cable can effectively increase anti-external disturbance performance；The mica tape packed layer of cable plays heat insulation, it is prevented that the effect of burn conductor；The insulating barrier of cable adopts fluorubber, it is possible to tolerance higher temperature；The high temperature resistance diaphragm saw lumber bed of material makes the heat-resisting ability of cable obtain further raising；The glass fibre belting layer of cable and wirerope protective layer, serve the effect improving cable resistance to tension.

Detailed description of the invention

By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.

With reference to accompanying drawing 1; this utility model provides a kind of cable; this cable includes four cable inner cores, glass fibre belting layer 6, external shielding layer 7, the high temperature resistance diaphragm saw lumber bed of material 8, wirerope protective layer 9 and PPS layer 10 from inside to outside; described cable inner core includes three cable conductors 1, internal shield 3, insulating barrier 4 and colour band 5 from inside to outside successively, is mica tape packed layer 2 between described cable conductor 1 and internal shield 3.

In the present embodiment, described internal shield 3 and external shielding layer 7 are the metal organization levels worked out by tin plating soft copper band, and internal shield 3 has functioned well as the shield effectiveness between cable core, improves anti-interference, thus decreasing crosstalk；External shielding layer 5 can effectively increase anti-external disturbance performance.

In the present embodiment, described insulating barrier 4 is 26-41 type fluororubber layer, and fluorubber tolerance high temperature capabilities is strong, 26-41 type fluorubber can at 250 DEG C life-time service.

In the present embodiment, described high temperature resistance diaphragm prepared material is polyimide film, polyimide high temperature-resistant excellent performance, it is possible to use in high temperature environments for a long time.

In the present embodiment, the described wire sheathing that wirerope protective layer is braided steel wire, this wire sheathing can increase the resistance to tension of wirerope, increases the service life of wirerope.

In the present embodiment; the performance of cable is had important impact as the outermost layer of this cable by described PPS layer; PPS(polyphenylene sulfide) there is the resin that thermostability high (using temperature continuously up to 240 DEG C), mechanical strength, rigidity, flame retardancy, chemical proofing, electrical characteristic, dimensional stability, wear-resisting, creep resistance and anti-flammability are all excellent; and it has self-extinguishment, cable is had certain protective effect by this performance when breaking out of fire.
