缘片是一种绝缘材料，广泛用于电器、电子行业，该产品起绝缘、分隔等作用。绝缘片的绝缘性能与温度有密切的关系。温度越高，绝缘片的绝缘性能越差。为保证绝缘强度，每种绝缘材料都有一个适当的******允许工作温度，在此温度以下，可以长期安全地使用，超过这个温度就会迅速老化。按照耐热程度，把绝缘材料分为Y、A、E、B、F、H、C等级别。例如A级绝缘材料的******允许工作温度为105℃，环氧板价格一般使用的配电变压器、电动机中的绝缘材料大多属于A级。绝缘片耐压强度：绝缘体两端所加的电压越高，材料内电荷受到的电场力就越大，越容易发生电离碰撞，环氧板价格造成绝缘体击穿。使绝缘体击穿的最低电压叫做这个绝缘体的击穿电压。使1毫米厚的绝缘材料击穿时，需要加上的电压千伏数叫做绝缘材料的绝缘耐压强度，简称绝缘强度。由于绝缘材料都有一定的绝缘强度，各种电气设备，各种安全用具（电工钳、验电笔、绝缘手套、绝缘棒等），各种电工材料，制造厂都规定一定的允许使用电压，称为额定电压。使用时承受的电压不得超过它的额定电压值，以免发生事故。
