2. 4Melt blown fabric electrostatic polarizer (with electrostatic generator)Main features:
   4.1. Smaller in size, lighter in weight, more aesthetically pleasing, more reliable, easy to operate, fully functional, and convenient for outdoor use, it is an ideal and reliable product.
   4.2. Adopting process manufacturing, applying PWM high-frequency pulse width modulation technology, pulse train logic array modulation, using high-power IGBT devices, and utilizing high-frequency technology to increase frequency up to 100kHz, thereby achieving higher output high voltage stability and smaller ripple coefficient.
   4.3 According to the maintenance free design, the main components are made of imported technology from countries such as the United States, Germany, and Japan, which are durable and not afraid of continuous short circuit discharge to ground.
   4.4. High precision and accurate measurement. The voltage and current meters are both digital displays with a voltage resolution of 0.1kV and a current resolution of 0.1uA. The voltage meter on the control box directly displays the voltage value applied to the load test sample without the need for an external voltage divider during use, and the wiring is simple. The instrument has high and low voltage terminals for measuring leakage current
   The high-voltage end adopts a circular shielded digital meter display, which is not afraid of discharge shock and has good anti-interference performance, suitable for on-site use.
   4.5. High voltage regulation stability, smooth voltage regulation across the entire range, output voltage regulation using imported single multi turn potentiometers, smooth boosting process, high regulation accuracy, and designed with coarse and fine adjustment functions. The voltage regulation accuracy is better than 0.1%, the measurement error of voltage and current is less than 1.0%, and the pulsation factor is better than 0.5%.
   4.6. Negative polarity output, zero start, continuously adjustable, with various protection functions such as overvoltage, overcurrent, return to zero, grounding protection, and unique disconnection protection. The automatic protection circuit has strong functions, complete and reliable protection, ensuring safe operation. All technical indicators are superior to industry standards and superior to similar products.
   4.7. The addition of high-precision 75% VDC-1mA function brings great convenience to the measurement of zinc oxide lightning arresters. A gentle press does not require calculation. There is a 75% voltage function key on the control box of this instrument. During the lightning arrester test, when the current rises to 1000uA, the 0.75 button is turned on. At this time, the values displayed on the voltmeter and ammeter are 75% of the data. After completion, the boost knob should be immediately returned to the zero position, and the fine adjustment voltage knob should be returned to the zero position. The green button should be immediately pressed to cut off the high voltage and turn off the power switch. Conduct other experiments.
   4.8. Convenient overvoltage setting function, using a digital dial switch, can intuitively display the set voltage value, making your operation more flexible. The displayed value is in kV.
   4.9. There are three concealed support feet at the bottom, which increase the stability of the pressure doubling cylinder.
