Solutions: Petroleum Resistant Stranded Cables

Petroleum-Resistant Stranded Cables for Low-Voltage Control, Monitoring, and Safety

Windy City Wire petroleum-resistant stranded cables are designed for low-voltage control, signaling, and instrumentation in locations where gasoline, diesel, oils, and common hydrocarbons are present. Built around flexible stranded conductors with a tightly twisted 1-pair design (10–12 twists per foot), these cables deliver dependable signal integrity without shielding while standing up to petroleum exposure across a wide range of petroleum applications and industries.

Where these cables are used

• Retail fueling/forecourt systems – Submersible turbine pump (STP) control, dispenser control signals, emergency stop circuits, interlocks, relay coil control, valve actuation, and contact closures.
• Automatic tank gauging (ATG) – Level probes, water detection, temperature sensing, and remote annunciation circuits for underground and aboveground storage tanks.
• Leak detection and environmental monitoring – Sump and interstitial sensors, line leak detection, vapor recovery controls, and alarm loops.
• Lighting and controls – Canopy lighting control relays, photocell/lighting contactor control, timeclock and automation tie-ins.
• Security and facility systems – Low-voltage alarm loops, door contacts, gate access controls, and notification devices in petroleum-exposed areas.
• Process and instrumentation – 4–20 mA signals, discrete I/O, and RS-485/serial control between controllers, PLCs, sensors, and actuators in petroleum equipment skids.
• Bulk fuel, fleet, and terminal operations – Pump control, valve monitoring, and safety interlocks in bulk plants, cardlock/fleet fueling sites, and terminal transfer equipment.
• Generator and day-tank fuel systems – Solenoid valves, level sensors, and control loops for diesel day tanks and transfer pumps.
• Vehicle service and car wash areas – Control and sensor wiring near lubricants and cleaning chemicals where petroleum resistance is beneficial.
• Marine and aviation fueling – Control and monitoring circuits at marinas and airport ground fueling where hydrocarbon exposure is common.

Why petroleum-resistant stranded cables

• Petroleum resistance where it counts – THHN, TFN, and TFFN constructions include a robust nylon jacket that helps resist gasoline, diesel, oils, and many solvents typically present at fueling sites and maintenance facilities.
• Reliable low-voltage performance – Twisted 1-pair conductors (10–12 TPF) help minimize crosstalk and noise for control and instrumentation circuits without the added cost of shielding.
• Flexible installation – Stranded (19-strand) copper offers easier routing and terminations in conduits, panels, and equipment enclosures compared to solid conductors.
• 600-volt control and signal circuits – Suitable for a wide range of low-voltage control wiring scenarios where a 600 V rating is required.

Choosing the right insulation for the job

• THHN petroleum-resistant wire – Commonly used for control and signal wiring in conduit and equipment enclosures at fueling sites and industrial petroleum areas. A dependable choice for general-purpose control circuits exposed to oils and fuels.
• TFFN petroleum-resistant wire – Thin-wall, flexible construction is well-suited for tighter spaces, fixture/control wiring, and shorter conduit runs where added flexibility and chemical resistance are valuable.
• TFN petroleum-resistant wire – Similar to TFFN with a thin-wall profile; used for compact routing of low-voltage control and instrumentation where petroleum resistance is important.

Typical systems and integrations

• Forecourt automation – Connect controllers, sensors, relay panels, and emergency shutoff devices involved in dispenser and pump operations.
• ATG and leak monitoring – Wire float trees, water probes, overfill prevention indicators, and remote alarm panels back to the monitoring console.
• SCADA/PLC and remote I/O – Carry low-current signals for process feedback and interlocks between skids, panels, and control rooms in fueling and lube operations.
• Safety and compliance circuits – Support interlocks, E-stop loops, alarm relays, and notification devices tied to site safety systems.

Available options in this category

• AWG sizes: 14 AWG and 16 AWG to match common control and instrumentation needs and run lengths.
• Insulations: THHN and TFFN petroleum-resistant constructions for chemical resistance in hydrocarbon environments.
• Shielding: Non-shielded, twisted-pair design to balance noise performance and cost for most control circuits.
• Conductor/jacket color options: Yellow/Red, Black/Red, Black/White, Brown/White, Brown/Purple, Yellow/Brown, Yellow/Purple, Yellow/Blue, Orange/Yellow to simplify circuit identification across complex installations.
• Lengths: 1000 FT and 2500 FT to suit project scale and site layout.

Application guidance

1. Select 14 AWG for longer runs or where slightly lower voltage drop is desired; choose 16 AWG for shorter control and sensor circuits.
2. Use THHN for versatile control wiring in conduit where abrasion and chemical resistance are needed; choose TFFN when flexibility and a thinner wall help in tighter spaces.
3. Leverage the twisted 1-pair construction for stable 4–20 mA loops, RS-485 signaling, relay control, and dry contact circuits in petroleum areas.
4. Confirm system voltage, environmental conditions, and local code requirements for each installation and follow equipment manufacturer recommendations.

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

  THHN: Thermoplastic High Heat-Resistant Nylon. PVC insulation with a nylon jacket, 600 V, typically 90°C dry. Common for building wire in conduit and raceways where durability and chemical resistance (including petroleum exposure) are needed.
  TFFN: Thermoplastic Flexible Fixture Nylon. Similar materials but in a flexible, thinner-wall construction, 600 V, typically 90°C dry. Stranded for flexibility with a smaller OD—ideal for control panels, machine tools, and tight conduit runs.
  TFN: Thermoplastic Fixture Nylon. 600 V, typically 90°C dry. Fixture wire similar to TFFN but generally less flexible (often solid or stiffer construction), used in lighting fixtures and control circuits where flexibility is less critical.
  All three use a nylon jacket that enhances abrasion and chemical resistance; selection is typically driven by flexibility needs, bend radius, and space constraints. Always verify local code and application requirements.
