GPO-3绝缘板是由无碱玻璃纤维毡板浸以不饱和聚酯树脂糊，并添加相应的添加剂经热压而成的硬性板状绝缘材料。 GPO-3绝缘板，又称 UPGM-203 ，指的是不饱和聚酯玻璃纤维毡板材料，机械和电气用，高湿下电气性能好，中等温度下机械性能好，具有阻燃性，耐电弧和耐抗漏电痕迹性能佳
规格：1.0~100mm ，1200×2000mm
GPO-3绝缘板电绝缘性
所有电绝缘层压制品是天生的优质绝缘体。在此按照等级特征，利用其最佳化的特殊性能，在工程技术领域被广泛的应用于电气方面。
GPO-3绝缘板阻燃性能
Grades 1580和UTR是UL-rated V-0。Grade UTR不含卤素，系统在着火时发烟及毒烟都非常少。
机械强度
高强度玻璃纤维增强聚酯层压材料不会粉碎。因其隔离属性，刚性层压材料提供了结构支持。易曲的层压材料可利用于最小弯曲直径为19mm的应用。
耐热性能
Durostone® Glastic® 层压材料在升温过程中提供了卓越的保护特性和空间稳定性。这些层压材料在120-210℃电子和130-210℃机械范围内有着UL温度额定指标。
GPO-3绝缘板应用
在断路器中应用： 框架式断路器：安全挡板、安全遮板、间隔衬垫、相间隔板等。
塑壳式断路器中的应用：相间隔板、灭弧室隔弧板等。
在电机马达中应用： 电机电枢部件，活动盖板，槽楔定子、定垫片，薄垫片，碳刷座等
在开关设备中应用：隔板系统中的前端、后端、上端、底端、相间隔板等 其他应用：耐弧结构件
