The invention discharges air in the extrusion area by extruding the adsorption part, so that the adsorption part forms an internal and external pressure difference, provides supporting force for the cable by the action of atmospheric pressure, replaces the mode of fixing the cable by nailing a bracket, and reduces the installation cost and unnecessary installation steps.
Description
Technical Field
The invention relates to the technical field of cables, in particular to a novel fire-resistant flame-retardant power cable.
Background
Fire-resistant fire-retardant power cable is mainly applied to the power supply of large-scale mill and district, because traditional outer protective layer does not have adsorption efficiency in laying, need fix the cable through a large amount of supports of binding, it is pleasing to the eye to damage the wall, damage wall structure even, bind at some higher floors because workman high altitude construction intensity of labour is big, workman's protection instrument is simple simultaneously, often there is life danger, consequently need a novel fire-resistant fire-retardant power cable to solve above-mentioned problem.
Disclosure of Invention
In order to solve the technical problems, the invention provides a novel fire-resistant flame-retardant power cable. The technical problem to be solved by the invention is realized by adopting the following technical scheme:
the utility model provides a novel fire-resistant fire-retardant power cable, includes the conductor core, conductor core suit has insulating layer, flame retardant coating and outer protective layer, be equipped with on the outer protective layer along outer protective layer length direction parallel distribution and through the fashioned a plurality of absorption portion of machine tooling.
The adsorption part is internally provided with an extrusion area with an opening at the lower part, and the extrusion area enables the adsorption part to form an outer cover with uniform wall thickness.
And a filling layer is arranged between the conductive wire core and the insulating layer.
The interval between two adjacent adsorption parts 6 is 10cm-30 cm. .
The extrusion district opening is the rectangle and the opening size is along the direction grow gradually of keeping away from the conductive core.
The outer side surface of the adsorption part is inclined at a fixed angle with the axis of the outer protection layer.
The flame retardant coating is a high flame retardant polyolefin sheath layer.
The invention has the beneficial effects that: the invention discharges air in the extrusion area by extruding the adsorption part, so that the adsorption part forms an internal and external pressure difference, provides supporting force for the cable by the action of atmospheric pressure, replaces the mode of fixing the cable by nailing a bracket, and reduces the installation cost and unnecessary installation steps.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be described more clearly and more completely with reference to the drawings in the following embodiments, and it is understood that the described embodiments are only a part of the present invention, rather than all of the present invention, and based on the embodiments, other embodiments obtained by those skilled in the art without inventive exercise are within the protection scope of the present invention.
As shown in fig. 1 to 5, a novel fire-resistant and flame-retardant power cable comprises a conductive wire core 1, wherein the conductive wire core 1 is sleeved with an insulating layer 2, a heat-insulating layer 3, a fire-resistant layer 4 and an outer protective layer 5, and the outer protective layer 5 is provided with a plurality of adsorption parts 6 which are distributed in parallel along the length direction of the outer protective layer 5 and are formed by machining; the plurality of adsorption parts 6 ensure that all parts of the cable can be supported when the overlong cable is laid, and the phenomenon that the whole cable falls off because a single part cannot obtain supporting force is avoided; the outer protective layer 5 is integrally formed by an extruding machine, as shown in fig. 5, wherein the outer protective layer 5 comprises a protective layer 51 for the conductive wire core 1 to pass through and a protrusion 52, and the protrusion 52 is machined to form the adsorption part 6.
A squeezing area 8 with an opening at the lower part is arranged in the adsorption part 6, and the squeezing area 8 enables the adsorption part 6 to form an outer cover 9 with uniform wall thickness; air in the squeezing area 8 is exhausted by squeezing the adsorption part 6, so that the adsorption part 6 forms an internal and external pressure difference to provide a supporting force for the outer protection layer 5 under the action of atmospheric pressure.
And a filling layer 7 is arranged between the conductive wire core 1 and the insulating layer 2.
The interval between two adjacent adsorption parts 6 is 10cm-30 cm; the interval of the suction portions 6 may be changed at the time of production according to the use scene.
The 8 openings in the extrusion area are rectangular, and the size of the openings is gradually increased along the direction far away from the conductive wire core 1.
The outer side surfaces of the adsorption parts 6 are inclined at a fixed angle along the axis of the outer protection layer 5, so that the outer side surfaces can be dispersed towards the periphery when the adsorption parts 6 are extruded, and air in the extrusion area 8 can be conveniently discharged; the included angles between the two side surfaces along the length direction of the outer protection layer 5 and the two side surfaces perpendicular to the length direction of the outer protection layer 5 and the axis of the outer protection layer 5 are the same, and the included angle ranges from 40 degrees to 70 degrees.
The fire-resistant layer 4 is a high fire-resistant polyolefin sheath layer.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
