Features

1. High-Voltage Dielectric Integrity: Sintered high-purity ceramic barrel prevents internal flashover and electrical leakage at 15 kV to 20 kV exciter discharge pulses.
2. Erosion-Resistant Firing Tip: Engineered to withstand severe combustion gas temperatures and capacitive spark erosion across hundreds of light-off cycles.
3. Hermetic Gas-Tight Seal: Internal glass-to-metal / ceramic-to-metal sealing prevents high-pressure combustor gases from blowing back into the ignition lead connector well.
4. Vibration-Hardened Construction: Built to endure continuous high-frequency aeroderivative turbine vibration without insulator cracking or terminal loosening.
5. Direct OEM Drop-In Fit: Precision-machined mounting threads and coaxial lead terminal match GE LM1600, LM2500, and LM6000 combustor boss specifications.

Applications

• Naval & Commercial Marine Propulsion: Main propulsion gas turbines (GE LM2500) on naval combatants, fast ferries, and LNG carriers.
• Offshore Oil & Gas Platforms: FPSO power generation modules and gas compression turbine drives (LM1600 / LM2500 / LM6000).
• Land-Based Power Generation: Simple-cycle and combined-cycle peaking power plants utilizing GE aeroderivative turbines.
• Emergency & Auxiliary Turbine Packages: Rapid-start standby power units requiring immediate, reliable light-off.

Frequently Asked Questions

What gas turbine engines use the Unison 10-630225-1 (GE 9392M95P04) ignitor plug?

The Unison 10-630225-1 ignitor plug, cross-referenced as GE part number 9392M95P04, is designed for General Electric aeroderivative gas turbines, specifically the GE LM1600, LM2500, and LM6000 series used in marine propulsion and industrial power generation.

Are Unison 10-630225-1 and GE 9392M95P04 interchangeable?

Yes. Unison Industries (CAGE Code 07482) is the original equipment manufacturer of this ignitor plug for GE Aerospace. Part number 10-630225-1 is the Unison manufacturing number, while 9392M95P04 is the corresponding GE catalog part number.

What ignition exciter and lead pair with the 10-630225-1 ignitor plug?

This ignitor plug pairs with Unison ignition lead 650097 (GE 354A1513P152) and capacitive discharge ignition exciter 516635-1 (GE L63585P01), which delivers a 15 kV to 20 kV high-energy pulse to initiate combustion.

How can I tell if a gas turbine ignitor plug needs replacement?

Common indicators include delayed light-off, failed start sequences, visible center electrode erosion beyond OEM recessed gap tolerances, cracked ceramic insulation inside the terminal well, or carbon tracking along the insulator nose.

What does the “G” suffix on 10-630225-1 G indicate?

The “G” marking stamped on the ignitor shell denotes the engineering revision/series letter applied by Unison Industries during production. It remains fully form-fit-function compatible with standard 10-630225-1 and GE 9392M95P04 specifications.
