AB-3S-40.5 outdoor intelligent high pressure permanent magnet vacuum transducer
The AB-3S series transducer is the new generation of intelligent vacuum transducer with independent intellectual property rights. This is the actual situation of domestic, international advanced technology integration, China power distribution system and intelligent power supply requirements. It reflects our design philosophy, intelligence, energy saving, environmental protection, maintenance-free. This product is widely used in many substations and power distribution networks in China. It integrates measurement, control, protection, communication, fault location, network reorganization, which is in the end user and popular features. It is fully automated, highly intelligent, which makes itself the preferred automation and miniaturization of small-sized substation.
