Petroleum Resistant Pair Stranded Cables

Summary: Petroleum Resistant Pair Stranded Cables

Petroleum Resistant Pair Stranded Cables

Windy City Wire manufactures petroleum resistant pair stranded cables designed for low-voltage control, monitoring, and signal applications where incidental exposure to fuels, oils, and common petroleum-based fluids is expected. Built as part of our SmartWire registered trademark product line, these cables balance durability and flexibility to support reliable performance in fueling stations, car washes, maintenance bays, industrial machinery areas, convenience store forecourts, and other oil-prone environments.

Each cable features a stranded copper pair for easier routing and termination, along with a petroleum resistant jacket that helps maintain integrity when contact with hydrocarbons occurs. The twisted pair geometry helps with noise rejection in control and instrumentation circuits, supporting consistent signal quality across typical low-voltage installations such as tank monitoring, leak detection sensors, pump controls, access control devices, and emergency stop circuits.

Solutions: Petroleum Resistant Pair Stranded Cables

Petroleum Resistant Pair Stranded Cables are purpose-built for low-voltage control and signal circuits that live in and around fuels, oils, lubricants, and cleaning solvents. In forecourts, tank rooms, mechanical spaces, and process areas, these cables help ensure reliable communication between sensors, controllers, and safety systems while standing up to gasoline, diesel, ethanol blends, biodiesel, kerosene, and hydraulic fluids. Stranded copper conductors provide flexibility for tight spaces and vibration-prone equipment, while petroleum-resistant insulation systems help maintain performance in wet, corrosive, and high-traffic environments.

Where these cables are commonly used

• Retail fueling and convenience stores – Automatic tank gauge (ATG) probes, overfill alarms, interstitial and sump leak sensors, line-leak detection devices, dispenser I/O and control circuits, price sign controllers, canopy control relays, and emergency stop interlocks.
• Commercial and fleet fueling depots – Dispenser control, forecourt communication, card-reader interface wiring, access control contacts, gate and barrier signals, and monitoring of aboveground storage tanks.
• Bulk terminals and tank farms – Low-voltage instrumentation loops (4–20 mA), valve position feedback, float switches, pressure/temperature transmitters, and alarm circuits exposed to hydrocarbon vapors.
• Refineries and chemical processing – Local control and instrumentation runs in oily or solvent-laden areas where petroleum resistance and flexible termination are priorities.
• Aviation and marine fueling – Hydrant or dock-side dispenser control wiring, leak detection circuits, and sensor connections subject to splash or vapor exposure.
• Emergency generator and day-tank systems – Fuel level senders, transfer pump control, leak detection, and overfill alarm wiring in mechanical rooms and outdoor enclosures.
• Vehicle maintenance and car wash facilities – Oil-water separator monitors, fluid management systems, and pump/valve control circuits exposed to oils and detergents.
• Mining, agriculture, and remote fueling – Low-voltage signaling for diesel storage, mobile tanks, and temporary fueling skids with frequent vibration and movement.

Integrations and systems supported

• Automatic Tank Gauging (ATG) – Reliable pair connections for probes, temperature sensors, interstitial and sump switches, and alarm outputs to building systems.
• Submersible turbine pump (STP) control – Low-voltage enable, status, and interlock circuits between STP controllers and dispensers or safety shutdown devices.
• Leak detection and environmental monitoring – Float switches, conductivity probes, hydrocarbon sensors, and annunciation circuits that require petroleum-resistant insulation.
• Forecourt communications and safety – Low-voltage signaling for dispenser interfaces, price signs, canopy control relays, and emergency stop chains.
• Process and instrumentation loops – 4–20 mA transmitters, dry contact closures, and low-noise signal runs; choose shielded constructions when EMI is present.

Why pair stranded construction excels in petroleum environments

• Flexibility and durability – Stranded conductors handle repeated maintenance cycles, conduit bends, and equipment vibration better than solid conductors.
• Clean terminations – Easier to land under field terminals and within compact device housings commonly found in dispensers and sensor enclosures.
• Chemical resistance – Insulation systems formulated to resist fuels, oils, and many solvents help preserve dielectric integrity and extend service life.
• Noise control options – Shielded pair variants help protect sensitive measurement signals in sites with motors, VFDs, lighting, and radio sources.

How petroleum resistant pair stranded cables fit with THHN, TFN, and TFFN

• Inside raceways and panels – Nylon-jacketed PVC building wires like THHN, TFN, and TFFN are frequently selected for branch circuits and internal equipment wiring in petroleum facilities because they are oil/gasoline resistant and heat rated for demanding spaces.
• Field device connections – Use petroleum resistant pair stranded cable to bridge from control panels and junction boxes to sensors, probes, switches, and low-voltage devices in areas likely to encounter fuel or oil. The flexible pair construction simplifies installation and maintenance.
• Division of roles – A common approach is THHN/TFN/TFFN for power and general control runs in conduit, with petroleum resistant pair stranded cable dedicated to low-voltage signals and control points exposed to hydrocarbons.

Typical low-voltage uses

• 4–20 mA instrumentation loops and sensor power leads.
• Dry-contact alarm circuits: overfill, leak, sump high-level, and emergency stop.
• Low-speed serial links and controller I/O where a single pair is sufficient.
• Relay and interlock control for dispensers, valve actuators, and pump enable lines.

Selection tips for your application

• Chemical exposure – Match the cable’s petroleum-resistant construction to gasoline, diesel, biodiesel blends, and ethanol-blended fuels present on site.
• Environment – Confirm suitability for wet locations, temperature range, abrasion potential, and UV exposure if runs extend outdoors.
• Electrical performance – Size conductors to your voltage drop and loop current needs; choose shielding where EMI is present near pumps, VFDs, and lighting.
• Code compliance – Coordinate wiring methods with the NEC, local code, and the authority having jurisdiction, especially in classified hazardous locations.

Industries that benefit

• Retail fuel stations and truck stops.
• Fleet fueling, municipal yards, and logistics hubs.
• Bulk terminals, midstream facilities, and tank farms.
• Refining, petrochemical, and industrial processing.
• Aviation, marine fueling, and ports.

• What is the main difference between THHN, TFFN, and TFN Petroleum wires?

  THHN (Thermoplastic High Heat-resistant Nylon): A 600 V building wire with a robust PVC insulation and nylon jacket, commonly used in conduit for feeders, branch circuits, and control wiring. In petroleum applications, THHN constructions employ compounds designed for oil/gasoline resistance and higher temperature performance.

  TFN (Thermoplastic Fixture Nylon): Typically a 600 V fixture wire with a thinner wall than THHN and usually a solid conductor, suited for lighting fixtures, panels, and control cabinets where compact routing is needed. Petroleum-rated TFN uses oil- and gasoline-resistant materials for environments with hydrocarbon exposure.

  TFFN (Thermoplastic Flexible Fixture Nylon): Similar to TFN but with stranded conductors for added flexibility, making it ideal for fixture leads, machine tools, and control wiring where frequent movement or tight bends occur. Petroleum-rated TFFN uses flexible, oil- and gasoline-resistant thermoplastic and nylon to handle exposure in fuel-handling or industrial settings.
