POLARIZATION CELL REPLACEMENT (PCR) "Raduga" SP-RA
 
-LIQID ELECTROLITE SP-RA-1
The SP-RA-1 polarization system consists of an electrolytic chamber filled with liquid electrolyte and electrodes made of a special alloy; the connection terminals and a valve with a cap are installed in the upper part of the system.

- SOLID STATE SP-RA-2
The SP-RA-2 polarization system consists of a housing with equipment and electrodes made of a special alloy; connection terminals are installed in the upper part of the system.
 
Polarization system "Raduga"  (polarization cell) is designed for direct current decoupling of equipment under cathodic protection from the grounding system of electrical equipment.
Purpose of the polarizing cell
• protection of insulating joints against overvoltage;
• suppression of the induced AC voltage;
• blocking of parasitic AC voltage;
• provision of permanent AC grounding at DC decoupling of structures under cathodic protection;
• providing DC decoupling of equipment with cathodic protection from grounding of the public power system;
• provision of equipment protection in the event of a lightning strike and transient processes of the ECP system.
 
The body material is made of polymer material, reinforced with fiberglass and provides a degree of protection against external influences at least IP55.
 
The SP-RA-X-V housing is made in an explosion-proof design (explosion-proof 1Ex d (ia) IIcT6), with explosion-proof cable leads, resistant to the negative effects of the environment and various chemicals, including vapors of hydrochloric acid and hydrogen sulfide. Body material - aluminum alloy without copper.
The casing sealing system has a labyrinth shape and provides a degree of protection against external influences at least IP67.

The enclosures can be equipped with fixings to the vertical base or inside the duct.
