Description
As one of the leading manufacturers of SF6 Ring Main Unit manufacturers, Fengyuan is committed to providing medium voltage RMU units from 11kV to 33kV.
The 11KV SF6 RMU for the secondary distribution network designed by Fengyuan Company has the advantage of uninterrupted power supply. The function of the ring host is to ensure the power supply. When the main power supply is turned off, the second power supply can supply power immediately.
The SF6 insulated ring main unit is one of the safest ring hosts on the market. The 11KV / 24KV ring host can provide 10 different configurations, which are suitable for most switching applications in the 11KV / 24KV distribution network.
There are three types of ring network cabinets on the market: gas insulated rmu, air insulated rmu, and solid insulated rmu. It is used to distribute load current, disconnect the short-circuit current and no-load current of the transformer, and control the charging current of overhead lines and cable lines from a certain distance. It is an important switching device for ring power supply and terminal power supply.
