In large-scale intelligent switching station, the 12 kV switchgears, 12 kV power supplies, PTs, FTUs, Feeding RTUs, geographic information systems(GIS), facilities management (FM), communication control terminals (CCU), 12 kV measurement and automatic meter reading devices, and others are installed in a movable, sealed and moisture-proof enclosure made of stainless steel. Therefore, the integration of the primary/secondary system of power distribution network and the modularization of the assembling can be realized.
Product features:
- The cabinet has provided with high resistance to corrosion.
- Compact structure, requiring small installing areas, convenient installation, high safety and reliability.
- High resistance to bending, high resistance to shock, high resistance to insolation, high resistance to radiation, high heat insulating capability.
- High anti-freezing property, high anti-cracking ability, high corrosion-proof capacity.
- High moisture-resistance ability and flame-resistance ability, Water condensation-proof.
- The wiring method of the product is flexible, the distributed or centralized FTU(DTU) can be used.
- The product can be used in outdoor condition, and is provided with special locking structure for the doors, perfect theft-proof and rainproof functions.
- The product is provided with comprehensive and high-efficiency function, as well as modular design. The functions can be selected flexibly in accordance with the actual requirements.
- The automatic system can be independent from the communication system. When the fault appears, it can separate the fault and recover power supply in high speed.
