| Abstract: | In order to study pre-ignition characteristics，smoke release and distribution characteristics of wire insulation under microgravity，hardware of the wire insulation was conducted. The facility can achieve the wire insulation preheating by overload. Advanced test technology is adopted to obtain the early signs of ignition and the distribution of smoke concentration in the flue gas. The experimental results valid that the hardware is safe and reliable，and it can make full use of the space experiment ability to ensure the realization of the scientific objectives. |
