Abstract
The invention discloses a shielding and insulating control cable for spaceflight, composed of two zinc-plated annealing aluminum conductor cable cores, four tin-plated copper conductor cores and five protection layers. The five protection layer sequentially include a silver-plated aluminum alloy wire shielding layer, a polytetrafluoroethylene propylene insulating layer, a nickel strip shielding layer, a butyronitrile insulating layer and a chlorosulfonated polyethylene sheath layer from inside to outside; the silver-plated aluminum alloy wire shielding layer is set to be the central layer of the cable, the two zinc-plated annealing aluminum conductor cable cores are symmetrically extruded between the silver-plated aluminum alloy wire shielding layer and the polytetrafluoroethylene propylene insulating layer, four zinc-plated annealing aluminum conductor cores are extruded in each zinc-plated annealing aluminum conductor cable core which is wrapped with three protection layers, and four zinc-plated annealing copper conductor cores are extruded in the gap of the polytetrafluoroethylene propylene insulating layer. The cable has the characteristics of excellent magnetic disturbance resistance, good shielding effect and resistance to oxidation, can be widely applied to the field of aerospace, and is light in weight.
