This product is suitable for indoor high-voltage switchgear with a three-phase AC frequency of 50/60 Hz and a rated voltage of 40.5 kV. It is designed for switching various types of loads and applications requiring frequent operation. This product represents the next generation of indoor medium-voltage switchgear with internationally leading technological standards. It can be used for control and protection in power plants, substations, power equipment, and power lines, as well as in applications requiring frequent operations. It is not only suitable for the construction of new substations but also for the upgrading and expansion of existing substations.
This product is suitable for use in ring-main and radial-type power grids with an AC frequency of 50/60 Hz and voltages of 12 kV, 24 kV, 36 kV, and 40.5 kV. It is designed for the reception (incoming lines) and distribution (feeder lines) of electrical energy. It can close and interrupt load currents. It can also be used to interrupt no-load long-line currents, no-load transformers, capacitor banks, and other similar applications. When equipped with a current-limiting fuse and a trip interlocking mechanism, the load switch-fuse combination device can interrupt larger overload currents and short-circuit currents. Application areas: residential area distribution, box-type substations, various secondary substations, switching stations, and other locations with high requirements for load switches.
Switch unit configuration and installation, compact and elegant structure, highly reliable and fully functional intelligent terminal device. It adopts a fully enclosed structure to achieve a fully enclosed and fully insulated solution, with intelligent primary equipment and built-in measurement, metering, relay protection, monitoring, and control functions. On-site construction is simple and convenient, saving space. It provides necessary detection information to the outside, facilitating operation and maintenance. Integrated vacuum arc extinguishing chamber utilizing APG technology to enhance overall insulation and environmental resistance performance. Internal dual voltage sensors integrated into the vacuum arc extinguishing chamber enable measurement of incoming and outgoing line voltages. The mechanism employs Ansoft-designed high-performance magnetic actuators, ensuring high reliability and maintenance-free operation.
This product is suitable for use in 12kV, 24kV, and 40.5kV outdoor AC overhead distribution lines. It is commonly used as a distribution line switch, sectional or branch switch, and user feed-in switch, providing a safe and reliable visible break point for line load switching and user needs. It can be operated manually, electrically, or remotely.
