The application for thermal protection technique of rocket electrical system’s cable network was briefly introduced.The necessity of the unified thermal protection research was discussed.The general research concept that validly gather the light cable network’s core,insulate layer,shield layer,plug with the thermal protection layer was put forward.By manufacturing the thermal protection materials,ascertaining the construction of thermal protection layer,trial producing the cable network of unified thermal protection,and simulating the thermal environmental testing,the present work results show that the cable network satisfy the total index requests,that the construction reduces weight and gets light and soft,the reliability increases and the assembly period shortens,etc.
