Combined Protection Unit BSZ for Cathodic Protection Systems

Block of joint protection BSZ (hereinafter - Block) is designed to work with cathodic protection stations in schemes with separate protection to eliminate the harmful mutual influence of neighbouring utilities. Current regulation in the Unit can be carried out stepwise, by shifting the adjustment jumpers and smoothly, by turning the rheostat knob. The unit is manufactured in two versions by channel conductivity: with "forward" and "reverse" conductivity. The block of "forward" conductivity differs from the block of "reverse" conductivity by the opposite polarity of diode switching on.
