Abstract：
 The invention discloses a kind of high power density extract electric heating element wire insulation seal device belongs to heating element insulation seal technology. Setting the inner cutting ferrule in the seal cutting ferrule, clamping screw into the cutting ferrule, compressing the inner cutting ferrule, the high-temperature insulation lead cross the inner cutting ferrule , it contacts tightly with the compressed deformation inner cutting ferrule; the cover of the heater seal link with the seal cutting ferrule. The invention uses the assembly structure composed of compress nuts, PTFE inner cutting ferrule and the seal cutting ferrule, it has overcame the shortage that the seal insulation end ages of the resin, it is easy to crack, impact of the insulation seal in present technology, the insulation is good when the device works for a long time in high power density, it achieved the effect that the electrode insulation impedance can be always bigger than 200M after it through the pressure test, pressure cycling test, temperature cycling test, temperature test .
