SQ8600 Series Distribution Terminal Unit (DTU)
Product Profile
SQ8600 DTU series is applicable to 10KV power distribution room, ring network cabinet, switching station, distribution substation, switching station, etc. DTU supports the main station. It adopts centralized control mode, which can avoid multiple reclosing of feeder outgoing switches, locate and isolate faults accurately and quickly, and the time of isolating faults is not affected by the line distance and the number of line segments. The power supply can be restored according to the optimal economic solution.
