insulation and breakdown

During the long operational time, the film insulation is exposed to the electrical, thermal and mechanical stresses, which will cause insulation degradation and lead to breakdown finally.

绝缘薄膜材料在长期的运行过程中，受到电、热、机械和环境因素的联合作用，其性能将因此逐渐变坏，并最终导致绝缘击穿。

The heat fault of the electric equipment can cause insulation down and breakdown and makes the equipment damage, even gives rise to fires.

电气设备热故障会导致绝缘下降并击穿，使设备损坏，甚至引起火灾。

This paper introduces a class H insulation system of shield motor. The new insulation system is better than of silicon in irradiation resistance, breakdown strength, mechanical properties and so on.

本文介绍了一种新型H级屏蔽电动机的绝缘体系，在耐辐照方面它大大优于有机硅绝缘体系。
