The Teleflex SX intelligent pulse reflector is a high-end pulse reflector in SebaKMT products, which has opened up a new era of sampling frequency of 400MHz and is suitable for fast and intelligent fault location of 380V-220kV power cables. After cooperating with SPG32 or SPG40 high-voltage units, SX can achieve 15 arc reflection sliding technology under the premise of automatically extending the arc action time. SX integrates Δ U fully automatic triggering, no need to manually adjust pulse delay, and the on-site working time of charging batteries is extended to 4 hours. The touch screen control and one key dual operation mode added to SX are favored by cable professionals born in the 1980s and 1990s.
