What is the advantage of glass insulator:
High mechanical strength
Glass insulators can withstand significant mechanical loads, including the weight of the conductor itself, wind loads, ice loads, etc. It can still firmly support the conductor on the tower to ensure the safe and stable operation of the transmission line in severe weather conditions, such as heavy wind, rainstorm, snowstorm, etc. For example, in coastal or mountainous areas that are frequently hit by strong winds, the mechanical strength advantage of glass insulators becomes particularly important.
Good insulation performance
Due to the insulation properties of glass materials themselves, they can effectively prevent current leakage in high-voltage transmission lines. Moreover, the insulation performance of glass insulators is relatively stable and will not significantly decrease over time, providing reliable guarantees for long-term stable power transmission.
Zero value self explosion
This is a very significant feature of glass insulators. When the insulation performance of glass insulators decreases to a certain extent, that is, when a "zero value" situation occurs, under the action of operating voltage, the glass insulators will automatically break (self destruct). This feature enables operation and maintenance personnel to easily detect faulty insulators, facilitate timely replacement, and greatly improve the safety and reliability of transmission line operation. Compared to other types of insulators, this self detection and warning function is a unique advantage of glass insulators.
The Production process flow:
The production process of glass insulators in Jiangxi Huayao Electric Co.,Ltd is as follows:
Mix raw material=>melt glass liquid=>press to glass insulator shape=> tempering treatment=>cold and shock test=> Glue assembly=> routine test and other test=> Finished products package
