Product advantages

---

·The SVR series automatic voltage regulating and stabilizing transformers for high-voltage feed lines track changes in line voltage, automatically collect and control signals from the circuit, and automatically adjust the transformer ratio of the device to ensure stable output voltage.
 
·The voltage regulating transformer produced by Hengfengshuai can automatically adjust the input voltage within a range of ± 20%, suitable for lines with high voltage fluctuations or voltage drops. This type of feeder voltage regulator is installed in series at the middle and rear of 3KV-38KV lines to adjust the line voltage within a certain range, ensuring the power supply voltage of users.
 
·The SVR series feeder automatic voltage regulator produced by Hengfengshuai is also suitable for substations where the main transformer does not have voltage regulation capability. This type of voltage regulator is installed on the outlet side of the substation transformer to ensure the voltage of the busbar on the outlet side.
 
·The SVR series feeder automatic voltage regulator is suitable for high or low voltage unstable places such as rural power grids, tunnels, oil fields, mining areas, chemical industries, substations, etc. At present, this product has been sold to developing countries such as Central Asia, Africa, Southeast Asia, and South America.
