Thermal insulation materials , requires both thermal conductivity and insulation, these two indicators is the first thing to consider. To thermal effects, the thermal conductivity of the level required to be determined according to the power supply, can not be generalized. But there is absolutely indicators can be used as a reference standard, and that is the thermal resistance. Or less in the case of the thermal conductivity, thermal resistance can be determined directly merits of thermal effects.
Now with the power supply, insulation and must be guaranteed. Some manufacturers put the breakdown voltage of very high standard, so that customers that insulation is very good, but they did not specify test conditions, in what thickness as a test standard. Commonly used in the power supply in the thermal insulation material thickness of 0.2mm-0.25mm, is not less than the breakdown voltage requirements of 3.0kV.
Can a product be accepted by the market, in addition to product performance depends on its reliability. Such as high-temperature aging, high temperature and high humidity, high and low temperature cycling conditions to determine whether a product is a stable job stability, reliability basic project.
