SERIES 107
Braided Ground Straps
for electrostatic discharge,
lightning strike and power
equipment grounding
A single lightning strike can hit an aircraft with as much as 1,000,000 volts. Static
electricity can charge an aircraft, particularly in cold and wet air, with enough
electrical potential to result in a discharge that can ignite ground fueling
equipment or fry avionics gear. Power generation systems (engines,
alternators, starters, etc.) can also produce transient electrical current that
can damage adjacent electronic systems.
Damage from these events is minimized and managed in aircraft,
Navy ships, mass transit systems and elsewhere through the use
of electrical bonding. Flexible bonding straps are attached
between equipment and airframes as well as between
structural elements and flight control surfaces to
conduct destructive electrical surges to ground or
to bus bar components capable of absorbing
significant amounts of transient voltage

WEIGHT-SAVING, LOW-PROFILE
ArmorLite™ ESD Grounding Straps
Single and dual layer, light and medium duty
Lightweight Glenair technologies for spot grounding are broadly utilized for grounding
airframe sections, dissipating static build-up in composite structures, dissipating lightning
strike energy, and grounding individual moving parts in complex equipment such as aircraft
landing gear
ArmorLite™ microfilament braid offers 70+% weight savings over standard NiCu braid—plus
advantages in virtually every category due to Glenair’s ability to fine-tune the makeup of the
material cross-section (core, cladding and protective plating) to the exact requirements of each
application. Glenair ArmorLite™ lightweight microfilament braids, and hybrid ArmorLite™ and
nickel braids are now approved for use by every major airframe and equipment manufacturer.

CUSTOM CAPABILITIES
Special application ground straps
Fast turnaround on unusual/build-to-print requests
Custom and made-to-order configurations of our popular ground strap designs may be
built to exact customer specifications, leveraging the light weight, abrasion-resistance, and
conductivity of Glenair ArmorLite™ and/or conventional braid materials. Custom ground
strap configuration begins with selection of core filament material, cladding material, and
protection material elements to create the right weight and duty of grounding device for
each application. From small form-factor straps designed to resolve electrostatic discharge, to
larger form-factor flat and round braids for lightning strike and heavy equipment grounding—
Glenair has the right weight and duty of strap for the broad range of military and commercial
aircraft, Navy, and satellite applications.
