Product Description

High-voltage switchgear, also known as High-voltage switch cabinets,is a crucial piece of equipment in the power system, primarily used for making, breaking, controlling, and protecting during power generation,transmission, distribution, and energy conversion processes.
Functionally, high-voltage switchgear can quickly detect and respond to circuit abnormalities such as short circuits and overloads by timely cutting off the power supply to protect the system. Additionally, high-voltage switchgear helps maintain power quality by reducing voltage fluctuations and distortions, safeguarding equipment from damage. Furthermore, high-voltage switchgear is equipped with power measurement capabilities, providing accurate data for energy billing and power management.
