Hydraulic dielectric isolators are devices that meet the stringent lightning protection and ESD requirements plus the more demanding hydraulic system performance requirements. Leveraging over 20 years of dielectric experience, AWG designed the 1st hydraulic isolators in 2005 through an extensive design, analysis, and test program. We have delivered over 1000 ship sets of hydraulic dielectric isolators. There are two basic configurations: inline and bulkhead.  The function of Hydraulic Isolators is to provide lightning protection, dissipate static charge, carry hydraulic system pressures, and meet CFR 25.613 statistical basis for strength allowables.

• ​Current conduction and voltage withstand without arcing/sparking
• Fatigue Load Cycles (Pressure Impulse, Cyclic Flexure loading)
• Dielectric isolation properties
• Thermal insulation if required to surrounding structure threat loads (thrown tread, wing-tip tear-away)
• Threat loads (thrown tread, wing-tip tear-away)
• Hydraulic fluid cold soak and start-up
• Hydraulic fluid continuous operating and transient temperature range
• Hydraulic fluid temperature shock
• Altitude
• Vibration, shock, external static loads
• Fluid exposure (jet fuel, de-icing agents, water, others per RTCA/DO-160)
• Humidity
