The Rustrol® Cathodic Isolator®, Model: SSP-ATEX, and DC-Decoupler™ Model: DCD-ATEX 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 the utilities grounding network, such as:
- AC Fault Currents
- Lightning/Surge Currents
- AC Induced Voltages
- Power Switching Surge Currents
Rustrol® Cathodic Isolator®, Models: SSP.
The Rustrol® Cathodic Isolator®, Solid-State Surge Protector, Model: SSP is utilized where AC Mitigation and/or Lightning exposure are the primary concern to the "End-User" and offers a range of AC Fault Current exposures to accommodate most "End-Users" requirements.

Rustrol® DC-Decoupler™, Models: DCD
The standard Rustrol® DC-Decoupler™, Model: DCD Product Line provides an economical engineered solution in a compact, lightweight, ready to mount assembly. The Rustrol® DC-Decoupler™, Model: DCD is typically utilized within applications of light/moderate exposure of AC Fault Currents, moderate AC Mitigation/Discharge and lower lightning exposure (i.e. 75 kA @ 8/20 µs).

Rustrol® Cathodic Isolator®, Models: CI
The Rustrol® Model: CI is typically utilized for unique application such as, higher AC fault current conditions and/or higher DC Voltage Thresholds which are to be retained on the cathodically protected structure (i.e. Pipeline, Storage Tank etc.). The Rustrol®, Model: CI can achieve "End-User" requirements of AC fault Currents well in excess of 100 kA, 150 kA, up to 240 kA @ 1 cycle for 50 Hz or 60 Hz rms. The Rustrol® Cathodic Isolator®, Model: CI product line is available to provide DC Voltage Thresholds to meet the "End-User's" requirements, typically with the range of +/- 2.5 - 20 volts DC blocking potential.

Rustrol® Gas Gap™ Lightning Protector is a device that provides an electrical path (i.e. conductive mode) for isolating assemblies (i.e. Flanges/Monolithic Isolating Joints) during Electrical Exposures such as Lightning and Switching Surge Current.

Rustrol® Gradient Control Systems (GCS) provide a conducting path to the electrical utilities grounding network, utilizing the Rustrol®, Model: SSP or DCD (i.e. DC-Decoupling Device).
Brochure for the Rustrol® GCS can be found here: Rustrol Gradient Control Systems
Rustrol® Gradient Control System - MatTM (GCS-M) is utilized primarily to limit shock risks caused by localized "Step & Touch" voltage potentials that often occur within Valve Stations, Electrical Substations and enroute of pipelines at Test Station locations.

The Rustrol® Gradient Control System - Copper CableTM (GCS-CC) is often utilized for AC mitigation of hazardous voltages. This grounding/AC mitigation technique should be connected to the primary structure (i.e. pipeline) in series arrangement through a DC-Decoupling Device.
The Rustrol® Gradient Control System - Zinc RibbonTM (GCS-ZR) is typically connected to the primary structure (i.e. pipeline) in series arrangement through a DC-Decoupling Device at designated intervals to eliminate or reduce the coating stress voltage associated with high AC voltages originating from the Electric Power Transmission Corridor.
Rustrol® Cathodic Isolator® Fibreglass Pedestal, Model: CIFP-36 provides a free-standing, secure, maintenance-free secondary enclosure for mounting the Rustrol® Cathodic Isolator®, Model: CI, SSP or DCD (i.e. DC Decoupling Device).
