▲The deviation between reactance value of each phase and average value of three-phase reactance is ± 2%
▲It can meet the requirements of high temperature, large temperature difference, much dust, heavy salt fog, easy condensation and humidity.
▲It can meet the grounding requirements of the system center point, that is, it can operate for 2 hours under 1.732 times of overvoltage.
▲It can meet the requirements of long-term use in closed case, and the measured temperature rise of product design test is 35% lower than that of the national standard value of 100k.
▲The reliability of long-term operation. During the service life of 30 years, there is no insulation failure under normal service conditions.
