High Voltage Capacitor
ENHc series
ENHc high voltage capacitor is used in 50 Hz/60 Hz AC power system. It is mainly used to improve the power factor of the system, improve the voltage quality of the power grid, reduce circuit losses, improve transformer efficiency, and give full play to the efficiency of power generation and power supply equipment. It is very conducive to energy saving and efficiency, and brings huge benefits to power users and power supply system.
Characteristics of High Voltage Capacitors
¡ñDouble-sided coarsening "whole film" manufacturing technology is adopted for low loss.
¡ñAluminum foil: Aluminum foil with 4.5 micron electrical stability and good uniformity is adopted, and laser foil cutting technology is adopted.
¡ñImprove the stability and service life of capacitors, and use mechanical non-welding bonding, lower impedance, eliminating welding local heating.
¡ñThe insulating oil comes from ARKEMA, France. It has good local discharge, slow aging speed, non-toxic, environmentally friendly and degradable. Mechanical rolling type porcelain bushing, sealing flange and box body are TIG welded, never leaking oil.
¡ñENH high-voltage capacitor shell is made of stainless steel, never rust, using concave-convex punching technology, good smoothness and high mechanical strength.
¡ñUnique inner fuse protection: the inner fuse is placed between the two components, and there is an insulating village plate between the fuse and the adjacent components to prevent damage to the adjacent parts when the fuse moves, so as to improve the reliable operation of the products.
¡ñDischarge resistance is arranged in each series section of capacitor core, which can eliminate the overvoltage caused by the action of inner fuse besides discharging.
