Rustrol® Polarization Cell Systems |
| |
ICCC also manufactures the Rustrol® Polarization Cell Systems for worldwide distribution. As you probably know, Polarization Cells and the solid-state Cathodic Isolator® are an essential component for safely isolating cathodically protected structures (i.e. pipelines).
Rustrol® Systems are designed to protect personnel and equipment from electrical disturbances. Rustrol® Systems effectively block cathodic protection DC voltages; all other electrical disturbances are freely conducted to ground, such as:
- AC Fault Currents
- Mitigation of induced AC Voltages
- Lightning

The Rustrol® Polarization Cell Systems are rated for up to 100 kA AC fault current capacities, in 5 kA increments. Each Cell System is capable of blocking 1.7 volts DC. A full product line is available to meet the challenge of all applications.
Rustrol® Polarization Cell Systems are typically specified for earthing applications where major power disturbances are not the primary exposure. Some examples include: decoupling a structure from ground rods, casings or other isolated earths. AC power pulses, lightning surges, stray DC interference and induced AC voltages are all standard applications for the Rustrol® Polarization Cell. All Cells are rated to safely pass ½ second (30 cycle) AC fault current, with a terminal potential rise across the Cell, not exceeding 15 volts rms at 20°C.
Rustrol® Polarization Cells optimize the safety of personnel and equipment. Rustrol® Polarization Cell Systems are utilized to decouple massive metallic structures where electrical disturbances, caused by AC fault currents, present high-risk exposure. Typically, Rustrol® Polarization Cell Systems are specified for direct connections across isolation flange assemblies; between pipe-type cable systems and station ground; or between cathodically protected structures and the electrical grounding system neutral. |

Rustrol® Polarization Cells contain pairs of pure nickel plates immersed in KOH electrolyte. The surfaces of these plates instantly polarize when separated metallic structures are connected to opposite terminals. The polarizing film blocks DC, to contain cathodic protection current, while freely passing AC. Personnel are safely protected from shock hazards during AC faults. Insulating fittings and equipment are protected during electrical disturbances.
Separated underground or submerged metallic structures are efficiently protected. Isolated structures, which must remain effectively grounded to the AC utility network, are designed to meet this requirement in national electrical safety codes. Installations specifying Rustrol® Polarization Cells for cathodic isolation, are regularly accepted by North American electrical inspectors. |
