Abstract
The utility model discloses a kind of anti-rotationals to control cable, belongs to control field of cable technology.Including several conductors, insulating layer is extruded with outside the conductor, the insulating layer is coated with internal shield, the conductor, insulating layer and internal shield constitute insulated wire cores, one layer of elastic layer is extruded after the insulated wire cores twisted synthesizing cable, it is also plugged with several hollow separator tubes in the elastic layer, external shielding layer is extruded with outside the elastic layer, oversheath is extruded with outside the external shielding layer.The utility model cable extrudes elastic layer on the outside of insulated wire cores, while adding separator tube in elastic energy, reduces core torsional deflection rate, improves the anti-torsion performance of cable entirety；Equipped with internal shield and external shielding layer, outside electromagnetic interference is effectively prevented, ensures the normal transmission work of cable.
Description
Technical field
The utility model relates to control field of cable technology, specifically, more particularly to a kind of anti-rotational control cable.
Background technique
Control cable is the cable for being used for transmission control electric signal, and cable can be turned round constantly in carrying and installation process
Turn, torsion frequent in this way will lead to the Core misalignment inside cable, will lead to deformation, the fracture of cable when serious, influences electricity
The performance of cable, and cause safety accident.
Summary of the invention
To solve the above-mentioned problems, the utility model discloses a kind of anti-rotationals to control cable, and anti-torsion performance is good.
The utility model is achieved through the following technical solutions:
A kind of anti-rotational control cable, the cable include several conductors, and insulating layer is extruded with outside the conductor, described exhausted
Edge layer is coated with internal shield, and the conductor, insulating layer and internal shield constitute insulated wire cores, and the insulated wire cores are twisted into
One layer of elastic layer is extruded after cable, several hollow separator tubes are also plugged in the elastic layer, is extruded with outside the elastic layer outer
Shielded layer, the external shielding layer are extruded with oversheath outside.
The insulating layer is extruded by heat curing type polyolefine material.
The internal shield is foil shielding layer.
The separator tube is carbon bellows.
The elastic layer is made of thermoplastic elastic material.
The external shielding layer is made of semiconductive fluorubber.
The oversheath is the halogen-free and low-smoke flame-retardant polyolefin sheathed material of thermoplastics type.
Compared with prior art, the utility model has the beneficial effects that
The utility model cable extrudes elastic layer on the outside of insulated wire cores, while adding separator tube in elastic energy, drop
Low core torsional deflection rate, improves the anti-torsion performance of cable entirety；Equipped with internal shield and external shielding layer, effectively avoid
Outside electromagnetic interference ensures the normal transmission work of cable.
