A high rigidity insulated cord for a spacecraft mechanism

The invention discloses a high-rigidity insulating cable for a spacecraft mechanism, which is composed of a steel wire rope core assembly and an XETFE insulating layer coated on the surface of the steel wire rope core assembly, wherein the steel wire rope core assembly is composed of a plurality of steel wire rope cores. The thickness of XETFE insulation layer is 0.1 mm-0.15 mm. The rope of the invention can realize the high rigidity and insulation of the rope in the spacecraft mechanism, meanwhile, the XETFE material has the radiation resistance property, and the rope can be used in the spaceenvironment for a long time without aging, so that the reliability of the rope is ensured. 本发明公开种用于航天器机构的高刚度绝缘绳索，由钢丝绳芯组以及包覆在钢丝绳芯组表面的XETFE绝缘层构成，所述钢丝绳芯组由若干钢丝绳芯组成。XETFE绝缘层包覆的厚度为0.1mm～0.15mm。本发明的绳索可实现航天器机构中绳索的高刚度和绝缘性，同时XETFE材料具有抗辐照特性，在空间环境下长时间使用也不会老化，保证了该绳索使用的可靠性。
