Abstract
The invention discloses a flexible cold-resistant flat cable for a steel mill. The cable comprises a flat outer sheath, at least two sets of first cable cores and a set of second cable cores, wherein the outer sheath wraps the first cable cores and the second cable cores; the second cable cores are arranged in the center of the outer sheath, and the first cable cores are symmetrically distributed on two sides of the second cable cores; the first cable cores comprise first conductor layers and first insulating layers, wherein the first insulating layers wrap the first conductor layers; the second cable cores comprise inner sheaths and at least two sets of third cable cores, wherein the inner sheaths wrap the third cable cores; the third cable cores comprise second conductor layers and second insulating layers, wherein the second insulating layers wrap the second conductor layers. For the flexible cold-resistant flat cable for the steel mill provided by the invention, the situation that when the cable is used in a dragging process in a low-temperature environment, the cable is broken and damaged is prevented.
Description
Technical field
The present invention relates to field of cable technology, particularly relate to the flexible cold-resistant flat cable of a kind of steel mill.
Background technology
Cable, as the important carrier of Signal transmissions, is widely used in all trades and professions, but at some extreme environments, the bending property of cable and low temperature resistivity not, can cause cable easily to be lost in actual use, urgently improve.
Summary of the invention
For solving in background technology the technical problem existed, the present invention proposes the flexible cold-resistant flat cable of a kind of steel mill, when can effectively prevent cable from using at low ambient temperatures, loses pulling in process.
The flexible cold-resistant flat cable of a kind of steel mill that the present invention proposes, comprise: the oversheath in flat, at least two group first cable cores, one group second cable core coated by oversheath, the second cable core is located at the center of oversheath, and the first cable core is symmetrically distributed in the second cable core both sides;
First cable core comprises: the first insulating barrier of the first conductor layer, coated first conductor layer;
Second cable core comprises: inner sheath, by coated at least two groups the 3rd cable core of inner sheath, described 3rd cable core comprises: the second insulating barrier of the second conductor layer, coated second conductor layer.
Preferably, between inner sheath inwall and the second insulating barrier outer wall, packed layer is provided with.
Preferably, the first conductor layer, the second conductor layer all adopt that stranded copper wire is stranded to be formed.
Preferably, the first insulating barrier and the second insulating barrier all adopt flexible ternary ethylene-propylene rubber to make.
Preferably, oversheath and inner sheath all adopt flexible flame retardant neoprene to make.
The flexible cold-resistant flat cable of a kind of steel mill that the present invention proposes, not only possesses higher flexibility, and is applicable to using at low ambient temperatures, pulls in process not easily lose in stretching.
Accompanying drawing explanation
Fig. 1 is the structural representation of the flexible cold-resistant flat cable of a kind of steel mill that the present invention proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of the flexible cold-resistant flat cable of a kind of steel mill that the present invention proposes.
With reference to Fig. 1, the flexible cold-resistant flat cable of a kind of steel mill, comprising: the oversheath 3 in flat, at least two group first cable cores, one group second cable core coated by oversheath 3, second cable core is located at the center of oversheath 1, and the first cable core is symmetrically distributed in the second cable core both sides; Because oversheath 3 is in flat, make its overall structure possess higher flexibility, pull in process not easily damaged.
First cable core comprises: the first insulating barrier 2 of the first conductor layer 1, coated first conductor layer 1;
Second cable core comprises: inner sheath 6, by coated at least two groups the 3rd cable core of inner sheath 6, described 3rd cable core comprises: the second insulating barrier 7 of the second conductor layer 5, coated second conductor layer 5.
Between inner sheath 6 inwall and the second insulating barrier 7 outer wall, be provided with packed layer 4, overall structure can be made comparatively compact, not easily disconnect.
First conductor layer 1, second conductor layer 5 all adopts that stranded copper wire is stranded to be formed, and overall structure can be made to possess higher tension and anti-ly pull performance.
First insulating barrier 2 and the second insulating barrier 7 all adopt flexible ternary ethylene-propylene rubber to make, and not only can use at low ambient temperatures, and possess higher flexibility.
Oversheath 3 and inner sheath 6 all adopt flexible flame retardant neoprene to make.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
