Interprovincial Corrosion Control is the original developer and manufacturer of the Solid-State Rustrol^® Cathodic Isolator^® technology, utilizing state-of-the-art design and superior test proven, quality controlled components throughout the construction. The Rustrol^® Cathodic Isolator^® which features electronic/electrical construction throughout responds instantly and offers a 'FAIL-SAFE', maintenance-free performance in an electrolyte-free environment.

The Cathodic Isolator^® Solid-State Surge Protector, Model: SSP is a type of Cathodic Isolator^® manufactured with diode circuitry versus the Cathodic Isolator^® Model: CI utilizing thyristor circuitry.

The Cathodic Isolator^® Model: SSP remains the preferred product choice by 'End-Users' for most Pipelines, Above and Below Grade Storage Tanks and other similar cathodic protection applications whereby the need to block the protective DC current at the isolating assembly (flange/monolithic joint) remains crucial; however maintaining a safe and effective electrical grounding path remains paramount.

The Cathodic Isolator^® Model: SSP is typically utilized where AC Fault Current, AC Mitigation and/or Lightning exposure of the primary structure (i.e. Pipeline, On-Grade Storage Tank, etc.) are the primary concern to the 'End-User'.

The Cathodic Isolator^® Model: SSP is manufactured in common models with the DC Voltage Threshold typically set at 3 volts DC (optional DC voltages available), with AC Fault Current exposure of typically selected model not exceeding 70 kA @ 1 cycle /60 Hz rms (or 66 kA @ 1 cycle /50 Hz rms) in accordance with the SSP Selection Chart, as outlined within our technical brochures. DC Voltage Thresholds and other operating parameters are to be specified by the customer.

The Cathodic Isolator^® Model: SSP utilizes diode technology within the AC Fault Current Module, offering a more economical and efficient design; typically assembled to provide for superior AC Fault Current protection and to be polarity sensitive by design.

The Cathodic Isolator^® Model: SSP maintains safety standards for effective electrical grounding within the National Electrical Codes (NEC) and conform to the need for safe operating 'Step and Touch' potentials accepted worldwide (not to exceed 10 volts AC rms).

Applications for Cost-Effective Operation
Combined with performing a key role in safe and effective corrosion control, the Rustrol^® Cathodic Isolator^® Model: SSP also reduces both the capital and maintenance costs of cathodic protection Systems. Cost effective applications include:

• AC fault-current protection across isolating flanges, monolithic isolating joints and other devices;
• Mitigation of Induced AC on pipelines and other structures;
• Lightning protection for equipment, including Cathodic Protection Rectifier Systems;
• De-Coupling of the primary structure (e.g. fueling facility, pipe-type cable systems, etc.) from contact with the electrical utilities grounding network.

• Restriction of the required protective current to the surface of the primary structure to produce a uniform polarized level of protection;
• Minimization of stray DC current interference;
• Prevention of galvanic current between metallic structures.
