Abstract: This paper introduce the ground-based low pressure simulation tests of the Wire Insulation characteristic box that will aboard on SJ-10 scientific satellite (SJ-10). An experimental system with reduced pressure is established to simulate the microgravity environment. The effects of insulation type, insulation thickness and amplitude of the overloaded current on fire initiation characteristics of wire insulation have been investigated at the representative 3kPa environmental pressure. The temperature rise trend and the smoke emission characteristics of wire insulation during fire initiation are obtained. Compared with the results obtained at the normal pressure (1atm), the fire initiation features of wire insulation as the satellite fly in orbit, namely it is at 3kPa pressure, is predicted. The results provide important references for the choice of space experimental conditions in SJ-10 satellite.
