¤Adapt to the altitude of 2000~5000 meters in the plateau area. ¤Three characteristics of anti - low pressure, low temperature and temperature resistance. ¤Excellent heat dissipation function: internal use of multiple sets of cylindrical capacitor combined structure, the heat dispersion polymerization; capacitor shell side adopts a multi row louvered vents, top and bottom cover with a convection hole design, circulation cooling. ¤Cylindrical capacitance unique bakelite terminal, copper plate open type tensile explosion-proof device (patent:ZL 2013 1 0370567.3 ,ZL 2013 1 02449000.6), effectively reduce the calorific value of the terminal, the explosion-proof function is reliable. ¤Cylindrical capacitor using double sealing treatment, anti low pressure, low temperature function, to prevent leakage of shell deformation. ¤The insulation strength is increased and the temperature of the shell is reduced by adopting the anti radiation insulation paint capacitor shell. ¤Plateau dry type capacitor broke through the traditional oil, wax capacitor, due to the temperature of the defects, to ensure the reliability and safety of plateau dry capacitor.
