Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of control cables, and specifically relates to a control cable provided with a strength reinforcement layer. Background Art
[0002] Control cables are PVC-insulated and PVC-sheathed control cables suitable for use in industrial and mining enterprises, energy and transportation departments, and for control and protection circuits with an alternating current rated voltage of 450 / 750 volts or less. When in use, control cables are subject to stretching, extrusion, and torsion. However, the existing control cables have low strength, so they are prone to breakage when subjected to stretching, extrusion, and torsion, which affects the service life of the control cables. Therefore, we propose a control cable provided with a strength reinforcement layer. Content of the Utility Model

[0004] To achieve the above purpose, the utility model provides the following technical solution: A control cable provided with a strength reinforcement layer includes an inner sheath. A filling layer is arranged inside the inner sheath. Three conductors are arranged inside the filling layer. Insulation layers are arranged on the outer side walls of the three conductors. A shielding layer is arranged on the outer side wall of the insulation layer. A waterproof layer is arranged on the outer side wall of the inner sheath. A reinforcement layer is arranged on the outer side wall of the waterproof layer. A high-temperature resistant layer is arranged on the outer side wall of the reinforcement layer. An armor layer is arranged on the outer side wall of the high-temperature resistant layer. An outer sheath is arranged on the outer side wall of the armor layer.
[0005] Further, the filling layer is made of polyethylene filler.
[0006] Further, a reinforcement frame is embedded inside the filling layer. The reinforcement frame is arranged in a triangular shape, and three corners of the reinforcement frame are connected to the inner side wall of the inner sheath.
[0007] Further, three reinforcing ribs are embedded inside the filling layer. The three reinforcing ribs are arranged inside the reinforcement frame, and the outer side walls of the three reinforcing ribs are in contact with the inner side wall of the reinforcement frame.
[0008] Further, the armor layer is made of steel wire braiding.
[0009] Further, the reinforcement layer is made of steel strip.
[0010] Further, the outer sheath is a PVC sheath.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: With the cooperation of the reinforcement frame, reinforcing ribs, reinforcement layer and armor layer, the present utility model can improve the service strength of the control cable, and the control cable will not break when being stretched, extruded and twisted during use, thus prolonging the service life of the control cable; Under the action of the high-temperature resistant layer, the high-temperature resistance performance of the control cable can be improved, and the normal use of the control cable will not be affected in a high-temperature environment. Under the action of the waterproof layer, the waterproof performance of the control cable can be improved, and the control cable will not seep water in rainy days. Brief Description of the Drawings
