Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

As shown in fig. 1, the utility model discloses an anti-torque high temperature resistant cable for aerospace, including buffer spring 7, first protective layer 1, gather power shroud 2, second protective layer 4 and

many conductors

6, 1 internal surface of first protective layer is provided with second protective layer 4, gathers power shroud 2 and sets up between second protective layer 4 and first protective layer 1, and buffer spring 7 and many conductors 6 parcel are in second protective layer 4, and many conductors 6 use buffer spring 7 to be the circumference array distribution as the center.

First protective layer 1 and second protective layer 4 can adopt the polyurethane material preparation to form in this application, also can adopt other materials to make such as other materials such as plastic-aluminum composite tape, fire-resistant composite tape certainly, and the user can carry out the adaptation according to actual need, does not restrict in this application.

When the cable is laid, if twist reverse the cable, gather the resistance that power shroud 2 itself has and become and can prevent that the number of turns of twisting around is too much to produce on avoiding the cable and gather the power, and then avoid the cable to twist around together, buffer spring 7 that sets up simultaneously, can help the cable to restore to the original state to a certain extent when making the cable distortion, with the holistic antitorque performance of effective improvement cable.
