Quartz glass tube has high dielectric strength and low conductivity. It can still maintain high dielectric strength and resistance under high temperature, high pressure and high frequency. There is almost no dielectric loss in wave band applications, so the performance of quartz glass is excellent at high temperature Dielectric insulation material.
