Aircraft Grounding Cable | PUR Refueling Wire
Critical Equipotential Bonding for Aviation Safety Designed to prevent catastrophic static discharge during aircraft refueling and maintenance, our highly flexible aircraft grounding cables ensure secure equipotential bonding. Featuring a severe-duty green-yellow PUR outer sheath with a built-in orange abrasion indicator, this single-core cable offers maximum safety and visual maintenance alerts for busy airport aprons.
- Core Advantage: Built-in orange visual abrasion warning indicator.
- Durability: Heavy-duty PUR jacket resists aviation oils, fuels, and tarmac friction.
- Flexibility: Class 5 fine copper stranding for rapid deployment and coiling.
- Direct from Factory: Custom manufacturing available for global GSE and EPC contractors.
Aircraft Grounding Cable: Uncompromising Safety for Aviation Refueling
Static electricity buildup during aviation refueling or ground maintenance poses a severe fire and explosion hazard. Standard grounding wires often stiffen, wear out quickly on abrasive concrete, or snap internally under constant tarmac movement. Engineered specifically for Ground Support Equipment (GSE), TEBAOFLEX’s flexible aircraft grounding cables provide a robust, wear-resistant equipotential bonding connection between aircraft, mobile refuelers, and grounded hangar structures.
Key Engineering Advantages
- Dual-Layer Visual Safety System: Tarmac friction is brutal on cable jackets. We engineered this grounding cable with a tough green-yellow Polyurethane (PUR) outer sheath over a bright Orange EPR core insulation. If the outer jacket wears down from constant dragging, the orange layer provides an immediate visual warning to ground crews, allowing for replacement before the safety ground is compromised.
- Extreme Weather & Oil Resistance: Airport aprons expose equipment to jet fuel, hydraulic fluids, and extreme weather. The specialized PUR sheath ensures long-term oil resistance and remains highly flexible even in freezing environments down to -40°C.
- High-Flexibility Copper Conductor: Utilizing Class 5 tinned fine copper strands, the cable is exceptionally pliable. This allows ground crews to easily handle, unroll, and recoil the cable multiple times a day without causing internal metal fatigue or strand breakage.
- Halogen-Free Safety Compliance: Safety in enclosed aircraft hangars is critical. This cable is completely halogen-free and flame retardant, meeting the strict requirements of IEC 60754-1 international standards for low toxicity and low corrosivity of gases during fire incidents.

Primary Application Scenarios
This heavy-duty grounding cable is the industry standard for safe electrical discharging in highly mobile aviation environments:
- Mobile Refueling Systems: Connecting aviation fuel trucks to the aircraft body.
- Passenger Boarding Bridges (PBB): Grounding connections at the terminal gate.
- Aircraft Hangars: Providing safe equipotential bonding during extensive Maintenance, Repair, and Overhaul (MRO) operations.
Frequently Asked Questions (Technical & Procurement)
Q1: Why is the internal insulation colored orange instead of standard black or white? A: The orange Cross-linked EPR insulation serves as a critical safety feature known as an “abrasion indicator.” Because aircraft grounding cables are constantly dragged across abrasive tarmac concrete, the outer green-yellow PUR sheath will eventually wear. Once the bright orange layer becomes visible, ground crews know instantly that the cable has reached its wear limit and must be replaced before the copper conductor is exposed.
Q2: Will this cable become stiff and difficult to unroll in winter conditions? A: No. Standard PVC cables become brittle in the cold, but our cable utilizes a premium Polyurethane (PUR) outer jacket combined with finely stranded Class 5 copper. This material composition guarantees that the cable retains its extreme flexibility and impact resistance even in harsh winter environments as low as -40°C.
Q3: How does the PUR outer sheath handle exposure to Jet-A fuel and Skydrol? A: Aviation environments are highly chemically aggressive. The PUR sheath we extrude is specifically formulated to be highly resistant to aviation fuels, synthetic oils, and hydraulic fluids (like Skydrol). It will not swell, crack, or degrade when exposed to these chemicals on the apron, significantly outlasting standard commercial cables.
Q4: Can TEBAOFLEX supply these grounding cables in bulk for our upcoming airport expansion project? A: Yes. As a direct manufacturer specializing in heavy-duty industrial and specialty cables, TEBAOFLEX serves global EPC contractors and GSE manufacturers. We can supply the standard 1×16 mm² and 1×25 mm² configurations in bulk drums, ensuring you bypass middleman markups while receiving fully certified, factory-direct products.
