据电力部门普遍反映玻璃绝缘子不易积污和易于清扫，南方线路运行的玻璃绝缘子雨后冲洗得较干净。
According to the general reflection of the power sector, glass insulators are not easy to accumulate dirt and clean, and glass insulators running in southern lines are cleaner after rain.
对典型地区线路上的玻璃绝缘子定期取样测定运行后的机电性能，从积累上千个数据表明运行35年后的玻璃绝缘子的机电性能与出厂时的基本一致，未出现老化现象。
The mechanical and electrical performances of glass insulators on typical area lines are measured by periodic sampling. The accumulated data show that the mechanical and electrical performances of glass insulators after 35 years of operation are basically the same as those when they are manufactured, and there is no aging phenomenon.
主容量大，成串电压分布均匀，玻璃的介电常数7-8，使钢化玻璃绝缘子具有较大的主电容和成串的电压分布均匀，有利于降低导线侧和接地侧附近绝缘子所承受的电压，从而达到减少无线电干扰、降低电晕损耗和延长玻璃绝缘子的寿命的目的，运行实践证明了这一点。
With large main capacity, uniform voltage distribution in series and dielectric constant of glass 7-8, toughened glass insulators have larger main capacitance and uniform voltage distribution in series, which is conducive to reducing the voltage borne by insulators near conductor side and grounding side, thereby reducing radio interference, reducing corona loss and prolonging glass insulation. The purpose of Sub-life is proved by operation practice.
