引言

目前市场上的普通母线槽产品因其材质与结构特点，难以在高温、干热等恶劣环境条件下稳定

运行。

本标准所规定的干热环境密集绝缘母线槽具有可在高温环境下长期稳定运行、耐冷热冲击、高绝

缘、高短路耐受强度等优点，绝缘电阻、介电强度、高温环境下温升、短路耐受强度、耐受温度变化

等指标满足GB/T19608.1—2022《特殊环境条件分级第1部分:干热》、GB/T7251.6—2015《低压成套

开关设备和控制设备第6部分:母线干线系统（母线槽）》等标准规定的高温、干热环境要求，可以在

新能源、数据中心、铸造、锻造、冶金等场所和沙漠等高温干热恶劣环境条件下安全使用。可有效克

服普通母线槽在干热环境下的弊端，实现了母线槽环境适用性的突破。

由于母线槽产品使用的环境条件是多方位的，其他类似产品达不到该类产品的应用场景，干热环

境密集绝缘母线槽的出现，可使用户清晰的了解该类产品，增加用户对母线槽产品的选择范围；也能

进一步规范产品市场，保持产品质量的稳定可靠，更好地服务于输配电行业的高质量发展。
