Introduction
The high voltage cable branch box (switching station) integrates the 12/24kV switch cabinet, circuit breakers, load switches, current and voltage transformers, 12/24kV supply PT, switching station FTU and RTU, communication control terminal (CCU), 12/24kV metering and automatic meter reading, UPS power supply, and indicating instruments. These components are installed, debugged, and housed within a movable, sealed, and moisture-proof stainless steel enclosure. Such design achieves the integration of primary and secondary systems in urban distribution networks and the modularization of assembly, thereby shortening the construction period and significantly enhancing the reliability of urban power grid operations.

Use conditions
>Altitude: ≤ 1000 m;
>Max ambient temperature: + 40 ℃;
>Min ambient temperature: -25 ℃;
>Max daily temperature difference: 25K;
>Indoor relative humidity: daily average≤ 95%, monthly average≤ 90%;
> Seismic resistance capability: Horizontal ground acceleration of 0.2g; vertical acceleration of 0.1g acting simultaneously. The testing methods used include resonance, sine wave, and beat wave tests. The excitation is performed 5 times, with 5 waves per excitation and an interval of 2 seconds between each excitation. The safety factor is not less than 1.67.
> The installation site should be free from gases, vapors, chemical deposits, dust, dirt, and other explosive or corrosive media that could severely affect the insulation of the load switch.
>Applicable for 10kV systems that are ungrounded, grounded through a small resistance, or grounded via an arc suppression coil.
