Smart Transformer Area Terminal
STTU12-HX01
The China Southern Power Grid Smart Transformer Area Terminal is an intelligent data collection and control terminal installed in public transformer areas. It features data collection, equipment monitoring, energy metering, power consumption management, and remote operation and maintenance, supporting the development needs of marketing, distribution, and emerging businesses.
Product Description
The China Southern Power Grid Smart Transformer Area Terminal (STTU12-HX01) is a core device for the digital transformation of transformer areas in the new power system. It integrates functions such as electrical quantity monitoring, equipment status sensing, load control, edge computing, and multi-mode communication, complying with China Southern Power Grid’s Q/CSG enterprise standards. The terminal adopts a modular hardware architecture and independently controllable “State Grid Chip,” suitable for outdoor wide temperature environments from -40℃ to +70℃, with an MTBF exceeding 30,000 hours and a service life of more than 10 years. It enables transparent management of the entire “transformer-line-user” data chain in the transformer area, supporting intelligent patrol and maintenance and refined user-side operations.
