Description
Technical field
This utility model is related to technical field of electric wires and cables, more specifically refers to a kind of multiple field cable.
Background technology
With the utilization of cable it is more and more extensive, the requirement more and more higher to cable, for now, the protection to cable
Just for certain point deprotection, such as, just for fireproof characteristic, or just for etch-proof characteristic, and have ignored complete
The protection in orientation, therefore, it is necessary to design a, multiple protective type cable lifts the performance of cable.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of multiple field cable.
For achieving the above object, this utility model is employed the following technical solutions：A kind of multiple field cable, including insulated wire cores
Protective layer, cable core, fire prevention sheath, metal armor layers, oversheath, described cable core include a plurality of being provided with the covered wire
The insulated wire cores of core protective layer, described insulated wire cores are made up of conductor and the wrapped insulating barrier on conductor, described cable
It is coated with described fire prevention sheath, metal armor layers on the outside of core successively, described oversheath is extruded in the metal armor layers
On.
Wherein：Described cable core is made up of two, three, four or five bar insulation cores.
Wherein：Inorganic fire-retarded gasket for packing is filled with described cable core center gap.
Wherein：The vertical bag of described metal armor layers is on the fire prevention sheath.
Wherein：Described oversheath is insulating barrier or outer jacket.
This utility model beneficial effect compared with prior art is：A kind of multiple field cable, can be according to different demands
The core number of cable, insulated wire cores outer surface is selected to be provided with insulated wire cores protective layer, prevent insulated wire cores exhausted in process cable core
Edge layer is rubbed and is damaged, and inorganic fire-retarded gasket for packing is filled with the space at cable core center, prevents insulated wire cores from twisting
Comburant oxygen in the space stayed during composite cable core, metal armor layers improve the intensity of cable and prevent mechanical damage
Wound, improves the service life of cable.
Description of the drawings
Fig. 1 is a kind of structural section schematic diagram of multiple field cable specific embodiment of this utility model；
Reference
10 conductor, 40 insulated wire cores protective layer
20 insulating barrier, 50 inorganic fire-retarded gasket for packing
The fire prevention sheath of 30 insulated wire cores 60
70 metal armor layers, 80 oversheath
Specific embodiment
In order to more fully understand technology contents of the present utility model, with reference to specific embodiment to skill of the present utility model
Art scheme is further described and illustrates, but is not limited to this.
Specific embodiment as shown in Figure 1, a kind of multiple field cable of this utility model, including insulated wire cores protective layer 40,
Cable core, fire prevention sheath 60, metal armor layers 70, oversheath 80, cable core include a plurality of being provided with insulated wire cores protective layer 40
Insulated wire cores 30, insulated wire cores 30 are made up of conductor 10 and wrapped insulating barrier 20 on the conductor 10, on the outside of cable core successively
Fire prevention sheath 60, metal armor layers 70 are coated with, oversheath 80 is extruded on metal armor layers 70.
In the present embodiment, cable core number is four, in other embodiment, cable can may be selected according to different demands
Core number is two, three or five.
Further, high fire-retardance cordage 50 is filled with the space at cable core center, prevent insulated wire cores 30 from twisting
Comburant oxygen in the space stayed during composite cable core.
Wherein, the thin protective layer of covered wire 40 is extruded on the outer surface of insulating barrier 20, protects insulated wire cores 30, prevents insulation
The insulating barrier 20 in process cable core of core 30 is rubbed and is destroyed.
Further, on fire prevention sheath 60, metal armor layers 70 can prevent mechanical damage to the vertical bag of metal armor layers 70
Wound, improves the intensity of cable.
Wherein, oversheath 80 is extruded on metal armor layers 70, if metal armor layers 70 do the neutral conductor, the sheath is
Insulating barrier is done, outer jacket can be done again.
In sum, a kind of multiple field cable, can select the core number of cable, 30 appearance of insulated wire cores according to different demands
Face is provided with insulated wire cores protective layer 40, prevents the insulating barrier in process cable core of insulated wire cores 30 from being rubbed and being damaged, in electricity
Inorganic fire-retarded gasket for packing 50 is filled with the space at cable core center, prevents insulated wire cores 30 from staying during cable core is twisted into
Space in comburant oxygen, metal armor layers 70 improve and the intensity of cable and prevent mechanical damage, improve making for cable
Use the life-span.
It is above-mentioned only with embodiment further illustrating technology contents of the present utility model, be easier to understand in order to reader,
But do not represent embodiment of the present utility model and be only limitted to this, it is any to extend or recreate according to the technology done by this utility model,
Be defined by claims by protection of the present utility model, protection domain of the present utility model.
