Product Introduction

IVL-MK high-voltage power capacitors use polypropylene film that is easy to impregnate as the full-film dielectric, and use environmentally friendly insulating oil as the impregnant. The box shell is treated with a special stainless steel process, with high explosion-proof specifications and strong corrosion resistance, ensuring the safety of use. Each capacitor component has fuse protection (internal fusing or external fusing protection), and each capacitor has an attached discharge resistor.

IVL-MK high voltage power capacitors are used to improve power factor, reduce line loss, improve transformer efficiency, filter out certain harmonics, system voltage support, reduce distribution cable cross-section, improve power transmission capacity, and achieve the purpose of energy saving and emission reduction.

 

Features

●Full-membrane dielectric
●Low loss
●Light weight
●Low failure rate
●Internal fuse and component isolation structure made by special technology, completely eliminate the occurrence of internal fuse rejection, misoperation and group explosion, making the product reliable Higher sex.
●The aluminum foil electrode of the capacitor element is automatically folded at the end and edge, which improves the electric field distribution at the edge of the electrode plate, thereby improving the partial discharge level of the capacitor; the element is rolled in an ultra-purified state, and a special pressure oil injection dipping process is adopted to make The product has the characteristics of low loss, low partial discharge and long life.
●The box body is welded by CNC automatic tungsten pulse argon arc welding, and the welding seam is flat and smooth, firm and without leakage. Ensure that the product has good sealing performance and explosion resistance. The box body adopts shot blasting treatment to improve the adhesion of the paint, and adopts the high-voltage electrostatic spray paint process, so the box body is corrosion-resistant and beautiful.
●Special gas is mixed with insulating oil. The trace moisture of the medium and the impregnant is one of the important issues that affect the partial discharge performance of the capacitor. This process can further remove the trace moisture in the oil medium, improve the partial discharge performance and electrical resistance of the capacitor, and more Good to promote the movement of the impregnant and facilitate heat dissipation. Reduce overall weight, have better reliability and longer service life.
●Environmental protection
●Non-toxic and non-polluting
●High safety
●Long life
●Each series section is equipped with a discharge resistor, high-quality high-voltage glass glaze film resistors can reduce the remaining voltage of the capacitor to 75V within 10 minutes after the power is disconnected the following. ●Advanced core assembly assembly line: The processes from component winding, pressure selection, internal fuse assembly, core pressing, wrapping, and boxing are all completed in a mechanized assembly line to ensure the quality of the core. ●The components are made of high-quality double-sided roughened high-quality polypropylene film and ultra-thin aluminum foil. The insulating oil used as the impregnant is a liquid medium with high insulation strength that is completely biodegradable (non-PCB), and does not contain chlorine or chlorination. Biphenyl, no pollution to the environment, low freezing point, low viscosity, good low temperature performance; good absorption capacity for gas generated by partial discharge, high ignition point, excellent overvoltage withstand capability, ensuring high product quality .
