Several typical international non-pyrotechnic clamp-band separation devices are introduced. The clamp-band is classifiedby clamp-band joint positionand the method of unlocking. The operating principle, application background and main performance characteristics of clamp-band separation devices based on thermal fusing, shape memory alloy, electronic trigger, thermoelectric nut trigger and motor driving are analyzed, and their advantages and disadvantages are pointedout. The current domestic research status of non-pyrotechnic clamp-band separation devices is introduced. The prediction of high- performance non-pyrotechnic clamp-band separation device is made on new materials, newelectronic devices and DC motors, and it provides the ideas of designing new clamp-band separation devices.
