cathodic system

the cathodic system is usually made up of the upper part, the lower insulation box, the insulator chamber with lead, the insulator chamber and suspension rod without lead, the cathode beam, cathode trabecula, cathode line and accessories.

cathodic line

the principle of the selection of cathode line is: sturdy and durable, low halo voltage, strong discharge, high corona current density, good rigidity and strong corrosion resistance.

the cathode line is usually made of 2205 materials. the rigid needle line is compared with the flexible cathode line, which reduces the halo voltage, greatly improves the line current density, and the volt ampere characteristic is better than the flexible line. there are fixed points in the upper and lower parts to prevent the fume from swinging through the gas, so as to meet the special requirements of the stability of the high gas velocity to the cathode system.

characteristics of different types of cathode lines:

tubular needle needle

zigzag line

the steel cathodic line is selected according to the firm reliability and the mechanical strength.

according to the degree of halo voltage, the order of arrangement is: tube shaped needle thread and belt serrated line.

according to the distribution uniformity of the plate current density, the order is: helix, starlike line, new tubular awning wire, tubular awn thorn line, saw tooth line, fishbone needle line and angle steel barbed wire.

according to the advantages and disadvantages of the curve of the volt - ampere characteristics, the order of the arrangement is: angle steel barbed line, sawtooth line, tube shaped pricking line, fishbone needle thread, spiral line and star line.

according to the adaptability of high concentration dust, the order of arrangement is: angle steel barbed line, sawtooth line, tube shaped pricking line, fishbone needle thread, spiral line and star line.
