Meta Description
Get the technical breakdown of the GE Vernova 362A3342P002 flame detector cable. Read about its 18.1-meter length, shielding, and environmental specs.
Main Body
When a gas turbine experiences a false “Loss of Flame” trip during peak load, the culprit is often not the optical sensor itself, but a degraded interconnecting cable running through the hot turbine compartment. The GE Vernova 362A3342P002 (also identified by engineering drawing number 7-21229-2) is a specialized, pre-terminated 2-wire shielded flame detector cable assembly. It is engineered specifically to transmit low-level microampere signals from Silicon Carbide (SIC) ultraviolet flame sensors back to the Mark VI or Mark VIe control cabinet.

By utilizing a molded IP67 connector system on both ends, this assembly prevents moisture, oil, and turbine wash chemicals from entering the junction points. The overall aluminum foil shielding combined with a dedicated drain wire shields the delicate flame signal from the high-frequency electromagnetic interference (EMI) generated by ignition exciters and turbine generator fields.
Do you have custom run lengths where you need to splice the cable? This pre-terminated, molded cable assembly is not recommended for field cutting or manual splicing. Damaging the molded ends or breaking the shielding integrity can introduce signal resistance, leading to false flame alarms.
Well, technically, the cable insulation is rated up to 125 °C, but it should still be routed through dedicated conduit and kept away from direct exhaust frame contact where temperatures easily exceed 300 °C. For standard 18.1-meter runs from the combustion chamber junction to the local terminal box, this cable is a critical spare. Keeping an original, factory-sealed cable in stock is an essential insurance policy to bypass long lead times during unplanned outages.
