Cathodic Protection rectifiers “UKZT-U” are intended for protection of underground metal constructions (pipelines) against corrosion by cathodic polarization method of . The CP rectifiers of this modification have all base properties of CPR “UKZT”, but they have increased dimensions for better cooling of elements and blocks of the CP rectifiers in conditions of high temperature of an environment at high values of protective currents. Thus the sizes of the external case and internal rotary chassis of the rectifiers are kept, that allows universal application of the rectifiers of “UKZT”, “UKZT-U” and “UKZT-TM” as on a design stage and at using.
The rectifiers “UKZT-U” are made in two modifications:
UKZT-1U OPE X,X Y1 – The cathodic protection rectifiers with manual control of output parameters (without automatic). This modification was cancelled from January 2016;
UKZT-AU OPE X,X Y1 – The automatic CP rectifiers with three regimes of work: manual control, automatic stabilization of output current (DC) or protective potential on protected construction. Also these rectifiers may be connected to some systems of remote control and operating. That function allows to provide remote control and operate parameters (protective potential, output current and voltage) of the rectifiers. This function may be included by preliminary request from Customer.
All CP rectifiers “UKZT” and “UKZT-U” have next features:
– Intuitively clear panel of control bodies ;
– Unique ergonomic design;
– Unpretentiousness 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.
