玻璃绝缘子的压力检测，主要核心内容：
内压力试验
此项试验专门针对空心瓷或玻璃绝缘子，用于检验其承受内部压力的能力。它是承压型空心绝缘子的关键机械性能指标之一。
The pressure test of glass insulator is mainly the internal pressure test. This test is specially for the hollow porcelain or glass insulator, and is used to test its ability to bear the internal pressure. It is one of the key mechanical performance indexes of the pressure-bearing hollow insulator.
