Abstract

The invention discloses a control cable. The control cable comprises a cable core, wherein the cable core is sequentially wrapped in a shielding layer, an insulation layer and an outer sheath layer from inside to outside, a bonding layer is arranged between the insulation layer and the outer sheath layer, the cable core is internally provided with three conductors, the conductors are sequentially wrapped in a conductor insulation layer and a thermal isolation layer from inside to outside, the cable core is internally provided with three arc-shaped insulation rubber plates, two ends of the three arc-shaped insulation rubber plates are respectively connected with an inner wall of the cable core to form three enclosed regions, the three conductors are respectively arranged in the three enclosed regions, and the cable core is internally provided with a cable core filler used for filling a cable core gap. The control cable is advantaged in that the temperature environment of the insulation layer and the conductor insulation layer is effectively controlled, the insulation layer and the conductor insulation layer are guaranteed to have excellent bending performance, and the use effect of the control cable is improved.

Description

technical field [0001] The invention relates to the field of cables, in particular to a control cable. Background technique [0002] During the use of existing control cables, due to frequent twisting and bending, the bending resistance of the insulation layer in the cable is very high, especially in some high-temperature environments, the insulation layer will accelerate aging in high-temperature environments , thereby reducing the bending resistance and use effect of the insulating layer, the insulating layer is very prone to damage or fall off, which seriously affects the use effect of the cable and shortens the service life of the cable. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, provide a control cable with a stable operating temperature environment of the insulating layer and high connection strength of the insulating layer. [0004] Technical solution: In order to achieve the above object, th...
