UEDZ OPE 1.8 Y1

Electro-drainage and cathodic protection rectifiers UEDZ are intended for protection of steel underground constructions in a zone of the electrified rail transport ways. This one distribute of a currents in system “rail – ground – underground construction”. Rectifiers UEDZ differs from the polarized electro-drainage devices presence by own source of a direct current and the block of automatic stabilization of protective potential on a protected construction. By construction, the UEDZ are hybrid devices having functions of cathodic protection automatic rectifier and the polarized electro-drainage device due to special circuit of the rectifier’s bridge. These drainages allow to increase considerably limits of adjustment of potentials on a underground construction due to inclusion of an additional source of a current in a circuit of a drainage.
Automatic electro-drainages UEDZ are irreplaceable at use in zones of wandering currents several sources.

The constructive and circuit decisions which applied in rectifier UEDZ, are completely  similar used in CP rectifiers UKZT-U series what causes presence of all advantages and features inherent for them:
– Intuitively clear panel of control bodies ;
– Unique ergonomic design;
– Unpretentious and safety in work;
– Universality and interchangeability of blocks and parts of the rectifiers;
– The compact and strong case from sheet steel 2мм;
– High-quality powder coating of metal parts of the case;
– Small weight
