NF M 87-202 EGFA Cable

What is NF M 87-202 EGFA Cable?

The NF M 87-202 EGFA cable is a low-voltage, collectively screened, double steel tape armoured (DSTA) multi-element instrumentation cable featuring Class 1 solid or Class 2 stranded copper conductors, PVC insulation, a PET binder tape, a collective AL/PET screen, an extruded PVC inner bedding sheath, double steel tape armour, and a light blue PVC outer jacket complying with NF M 87-202 and UTE C 32-014 standards. It is designed for fixed transmission of AC or DC analogue signals up to 300/500V in petroleum processing plants, refineries, petrochemical units, and chemical extraction facilities.

Engineered to deliver exceptional mechanical robustness and continuous signal fidelity in severe outdoor and underground processing plant environments, the cable integrates a collective AL/PET electrostatic foil shield that prevents electromagnetic interference (EMI) from disrupting delicate analogue circuits. Beneath the hydrocarbon-resistant outer jacket, two helically wound steel tapes form a rigid metallic barrier that withstands intense mechanical traverse crushing, stone impacts, and ground subsidence during direct burial, while the specialized outer PVC formulation resists swelling and chemical degradation from sunlight, mineral oils, and aliphatic hydrocarbons.

NF M 87-202 EGFA Cable Construction

• Conductor: Class 1 solid plain copper conductor (0.5mm² and 1.5mm²) or Class 2 stranded plain copper conductor (0.88mm²) per NF M 87-202 specifications.
• Insulation: Polyvinyl Chloride (PVC) compound engineered for dependable dielectric strength up to +90°C.
• Binder Tape: Polyester Tape (PET) wrapped over the assembled multi-pair or multi-triple cores to maintain cable geometry.
• Collective Screen: Aluminium/Polyester tape (AL/PET) providing 100% electrostatic coverage against external electromagnetic noise.
• Inner Sheath: Extruded Polyvinyl Chloride (PVC) bedding layer providing a uniform foundation for the metallic armouring.
• Armour: Double steel tape (DSTA) helically applied to deliver heavy-duty mechanical crush protection and direct burial capability.
• Outer Sheath: Flame-retardant Polyvinyl Chloride (PVC) compound resistant to sunlight, mineral oils, and aliphatic hydrocarbons.
• Core Identification: Pairs: White and Red cores with numbered printing; Triples: Blue, White, and Red cores with numbered printing.
• Sheath Colour: Light Blue.

Applications

NF M 87-202 EGFA cables are specifically engineered for interconnecting measuring instruments, flow transmitters, pressure sensors, thermocouples, and supervisory control desks across petroleum and petrochemical complexes where resistance to aliphatic hydrocarbons, mechanical damage, and direct burial are required. Their armored and shielded design ensures uninterrupted analogue communication even in physically hostile processing plant sectors.

Typical installation environments include:

• Petroleum Refineries & Hydrocarbon Units: AC and DC analogue sensor networks exposed to aliphatic hydrocarbon vapors and mineral oils.
• Direct Burial Applications: Underground cabling in plant trenches and raceways requiring double steel tape protection against stones and shifting earth.
• Intrinsically Safe Control Circuits: Hazardous-zone instrumentation systems identified via the standard light blue outer jacket.
• Chemical Processing & Bulk Fuel Storage: Fixed interconnections between field transmitters, monitoring junction boxes, and central control rooms.

Specifications & Dimensions

The NF M 87-202 EGFA cable portfolio covers multi-pair (1P, 2P quad, 3P, 7P, 12P, 19P, 27P) and multi-triple (1T, 2T, 3T, 7T, 12T, 19T, 27T) configurations across conductor cross-sections of 0.5mm² (Class 1), 0.88mm² (Class 2), and 1.5mm² (Class 1). Operating at a rated voltage of 300/500V, the cable supports continuous operating temperatures up to +90°C and installation temperatures from +5°C to +50°C. Conductor DC resistance values at 20°C are 37.9 Ω/km for 0.5mm², 21.6 Ω/km for 0.88mm², and 12.5 Ω/km for 1.5mm², while maximum mutual capacitance values range from 145 pF/m to 230 pF/m depending on core cross-section and screening geometry, with all nominal overall diameters manufactured in strict accordance with NF M 87-202 and UTE C 32-014 engineering tolerances.

Frequently Asked Questions

Q: What is the main structural difference between NF M 87-202 EISF and EGFA cables?
A: EISF is an unarmoured cable featuring both individual and collective screens for indoor tray installations, whereas EGFA is a collectively screened cable reinforced with double steel tape armour (DSTA) and an inner sheath specifically engineered for direct underground burial.

Q: Why does the cable feature a Light Blue outer sheath?
A: Light blue outer jacketing is the standardized color designation for intrinsically safe (IS) circuits within hazardous and potentially explosive areas, ensuring clear visual distinction from primary electrical power lines.

Q: What mechanical advantage does Double Steel Tape Armour (DSTA) offer over steel wire braid?
A: Double steel tape armour provides a continuous, overlapping metallic barrier that delivers vastly superior resistance against radial crushing loads, heavy compression, and stone penetration encountered during direct ground burial.

Q: What payment terms does Huadong Cable accept for international industrial export orders?
A: We accept standard international commercial payment terms including Telegraphic Transfer (T/T) and 100% Irrevocable Letter of Credit (L/C) at sight for engineering procurement contractors, petroleum refineries, and petrochemical facility integrators.
