How to solve the voltage problem at the end of the line?
In Northwest China, voltage instability at the user end is common during peak winter electricity consumption due to long transmission lines, often causing electrical appliances to malfunction. Heating and power supply facilities also frequently shut down, severely disrupting daily life. As a result, solving the problem of unstable voltage at the end of the power lines has become an urgent priority.
10kV Voltage Regulator: The “Intelligent Voltage Stabilizer” of the Power Grid
To tackle winter voltage fluctuations, after extensive research and technical evaluation, we ultimately selected the ZBSVR 10kV automatic voltage regulator. With its core advantages, this device effectively mitigates low voltage issues at the user end, delivering a stable and reliable power supply.
Wide-Range Voltage Regulation for Precise Control: Featuring an ultra-wide adjustment range of ±20%, it maintains voltage within an acceptable range—whether during peak or off-peak demand—preventing appliance malfunction due to voltage instability.
Adaptable to Long-Distance Transmission and Highly Versatile: It significantly extends the transmission capacity of 10kV voltage levels, making it well-suited to local grid characteristics such as long lines and heavy loads.
Maintenance-Free Design: Built with a fully sealed oil-immersed structure, it performs reliably in harsh environments. Its maintenance-free design reduces the need for outdoor work during winter.
Field Performance Comparison:
After the voltage regulator was put into operation, user-end appliances returned to normal function. Electric heaters and air conditioners operated stably, and grid maintenance efficiency improved significantly. The device is equipped with a combined bypass switch, allowing uninterrupted commissioning and decommissioning, which greatly enhances power supply reliability. At the same time, line losses and distribution losses were effectively reduced, making grid operation more economical and efficient.
