Application Fields
Electrical railways, metallurgy, petrochemical and other enterprise power grids, used for grounding fault current limitation and overvoltage suppression (to ensure safe operation of neutral point grounded systems).
Usage
Dry-type air-core neutral point reactors are mainly connected between the three-phase neutral point of high-impedance or transformers and ground, used to limit the line-to-ground current to an appropriate value during system fault grounding.
Main Technical Parameters
Rated Voltage: 35 ~ 66kV Rated Current: 100 ~ 500A
Product Features
Adopts imidazole system high-strength formula and mesh binding, V-type reinforced binding, multi-channel vertical binding and other processes to ensure the overall rigidity and stability of the product structure, which can effectively resist impact capacity after grounding short-circuit faults and ensure product safety and reliability.
