Abstract
The utility model relates to electric power cable, particularly a kind of Compression-resistincable cable.It comprises the main core be loaded in main pressure-bearing cover, and the some secondary cores be loaded on respectively in several secondary pressure-bearing covers, some secondary cores are symmetrically distributed in main core periphery, the side sidewall of described secondary pressure-bearing cover is connected with main core sidewall by connecting support bar, opposite side sidewall is overlapped with secondary pressure-bearing by connection support bar and is connected, described main pressure-bearing cover, secondary pressure-bearing cover and secondary pressure-bearing are filled with glass fibre between overlapping, secondary pressure-bearing cover outside is evenly placed with some rubber buffer pipes, rubber buffer pipe is wrapped in inner sheath, is enclosed with fire-resistant isinglass belt and oversheath outside inner sheath.Compared with prior art, the utility model cable has fire-resistant, resistance to compression dual characteristics.
Description
Technical field
The utility model relates to electric power cable, particularly a kind of Compression-resistincable cable.
Background technology
At present, middle pressure fire-resisting cable is iff relying on the material such as inorfil or Ceramic silicon rubber as refractory insulating layer, need to increase metal armor layers, but increase the weight that metal armouring thickness then adds cable, also the bending property of cable is made to reduce, add laid down cost and difficulty, can not instructions for use be met.
Utility model content
The purpose of this utility model is to provide a kind of Compression-resistincable cable having fire-resistant effect concurrently.
The purpose of this utility model is achieved through the following channels: a kind of Compression-resistincable cable, it comprises the main core be loaded in main pressure-bearing cover, and the some secondary cores be loaded on respectively in several secondary pressure-bearing covers, some secondary cores are symmetrically distributed in main core periphery, the side sidewall of described secondary pressure-bearing cover is connected with main core sidewall by connecting support bar, opposite side sidewall is overlapped with secondary pressure-bearing by connection support bar and is connected, described main pressure-bearing cover, secondary pressure-bearing cover and secondary pressure-bearing are filled with glass fibre between overlapping, secondary pressure-bearing cover outside is evenly placed with some rubber buffer pipes, rubber buffer pipe is wrapped in inner sheath, fire-resistant isinglass belt and oversheath is enclosed with outside inner sheath.
As the further optimization of this programme, described oversheath, connection support bar, main pressure-bearing cover and secondary pressure-bearing cover adopt polyolefine material to make.
A kind of Compression-resistincable cable of the utility model, compared with prior art, the utility model cable has following features: one is the oversheath in cable, main pressure-bearing is overlapped and secondary pressure-bearing cover adopts polyolefine material to make, and at core gap-fill glass fibre, substantially increase the fire resistant flame retardant of cable, and can not pernicious gas be released when burning, the safety of life and property of effective protection people; Two is adopt double-layer bumper technology, utilizes rubber buffer duct ligation to close the design connecting support bar, can promote resistance to compression effect further, greatly improve its flexibility, improve the adaptability of conductor.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
In figure, main pressure-bearing cover 1, main core 2, secondary pressure-bearing cover 3, secondary core 4, connection support bar 5, glass fibre 6, rubber buffer pipe 7, inner sheath 8, fire-resistant isinglass belt 9, oversheath 10.
Embodiment
As shown in Figure 1, a kind of Compression-resistincable cable of the utility model, it comprises the main core 2 be loaded in main pressure-bearing cover 1, and the some secondary cores 4 be loaded on respectively in several secondary pressure-bearing covers 3, some secondary cores 4 are symmetrically distributed in main core 2 periphery, the side sidewall of described secondary pressure-bearing cover 3 is connected with main core 2 sidewall by connecting support bar 5, opposite side sidewall overlaps 3 by connection support bar 5 with secondary pressure-bearing and is connected, connecting support bar 5 can effectively avoid external force to the punching press of core, described main pressure-bearing cover 1, secondary pressure-bearing cover 3 and secondary pressure-bearing are filled with glass fibre 6 between overlapping 3, glass fibre 6 has buffering concurrently, tamp and prevent fires triple function, some rubber buffer pipes 7 are evenly placed with outside secondary pressure-bearing cover 3, rubber buffer pipe 7 combines the design connecting support bar 5, resistance to compression effect can be promoted further, rubber buffer pipe 7 is wrapped in inner sheath 8, fire-resistant isinglass belt 9 and oversheath 10 is enclosed with outside inner sheath 8.
Described oversheath 10, connection support bar 5, main pressure-bearing cover 1 and secondary pressure-bearing cover 3 adopt polyolefine materials to make.
The above; be only embodiment of the present utility model; but protection range of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change can expected without creative work or replacement, all should be encompassed within protection range of the present utility model.Therefore, the protection range that protection range of the present utility model should limit with claims is as the criterion.
