  •     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。
