comment Isoler et dissiper l’impact de la foudre sur les ailes composites, éviter aussi les accumulations de charges électrostatiques. depuis l’accident du TWA800, il y a un standard mondialement utilisé (apparu en 2000) 14 CFR § 25.981 – Fuel tank explosion prévention.
Adel Wiggins fabrique depuis 1990 , soit 32 ans d’expérience des isolateurs
L’impact de la foudre sur les avions a un comportement différent avec un avion en aluminium ou un avion en composite voici les points clef de la performance des tubes en composite Adel Wiggins
Composite tubes can be used exclusively for the ENTIRE fuel
system or for specific fuel system dielectric isolation.
• Zero single point failures in over 17 years of installed service.
• Controls lightning induced current & allows for ESD.
Tested at 13 KV without sparking or arcing, minimal
temperature rise and absence of any damage or deterioration
Voltage waveform testing per SAE ARP5412
• Resistance can be modified per requirements.
• Fully qualified for environmental standards per RTCA/DO-160
• Capable of mating with standard or special fitting ends.
• Compatible with several types of fluids.
• Special connections or flanges (Sockets/Bulkheads/Panels)
• Aluminum, Steel or Titanium ferrules

The design for new aircraft in composites needs to take the charge out of atmospheric electricity in order to dissipate static charges, these static charges could be caused by lightning strike.
Adel Wiggins dissipate electrical charge from critical components within aircraft fluid conveyance systems.
The adel Wiggins Highly Resistive Union Insulative Fitting piping can meet all your request without the need of modification or increase of pressure drop.
