DSOP-II
Distribution System Over-voltage Protector
DSOP-II (SuPerDog) is switch-type protector. Its main technology is transverse-ignition and vertical-breakdown discharge gap (patent No. is ZL 03 2 54679.3). It has high current-passing capacity, and quick in response. It is suitable for the phase-I protection of waves (10/350μs or 8/20μs) along the lines of low-voltage distribution system
