Specifications
Weight Savings
Depending upon the cable construction, aluminum provides up to a 60% weight savings versus copper assemblies and is rated up to 175 °C
Gauge Sizes
Typical applications range in gauge sizes from #14 AWG to 4/0 (2.0 mm2 to 120 mm2)
Length Tolerances
- 0.25″ for assemblies ≤50″
- 0.50″ for assemblies >50″
Clocking Tolerance
± 10°
Amphenol CIT power and grounding cable assemblies are designed for the most demanding power and grounding applications in aerospace and are qualified to stringent specifications. In the sequence provided below, millivolt drop testing was performed both initially and after each test, and proved negligible degradation of the cable assembly.
| Salt Spray | 500-hour duration |
| Humidity/Temp Cycling | 400 cycles, cycling from 82 °C at 95% RH to 54 °C |
| Vibration | X, Y & Z axes |
| Tensile Testing | Following the environmental and vibration testing. As an example of a popular configuration, all #2 AWG samples exceed 500 Lbf |
| Environmentally Sealed & Hydrostatically Tested | 80 psi for 25 five-minute cycles with no leaking |
Environmentally sealed terminal lugs are designed for demanding power and grounding applications. Available in a wide variety of configurations, such as one-hole, two-hole, angled tongue, and narrow tongue configurations, ACIT terminal lugs can be selected to facilitate a wide range of termination and cable assembly installation needs. Standard connector body materials include lightweight aluminum for applications up to 175 °C and nickel-plated copper for applications up to 60°C.
Heat shrink applied over the transition from the lug barrel to the cable reduces strain forces that damage cables at this point in the assembly
We offer a variety of airframe cables, including Tufflite TLS (Thick Wall/Abrasion Resistant) & Tufflite TLA (Aluminum Conductor)
Facilitate cable identification & tracking
We can provide cable assemblies with terminal lugs oriented with respect to each other at a predetermined angle. Clocking reduces installation effort and time while reducing stresses on mounting surfaces.
No Special Tooling Needed
Eliminates the need to purchase and maintain expensive terminal lug installation tooling and the need to train installers on crimping procedures
Consistent, Precision Cable Assembly
Standardizing cable assemblies facilitates design to exacting standards, pre-determined cable dressing and assurance of proper fit
Complete Engine Power Feeder Solution
Can be combined and certified with terminal blocks, providing a complete solution to engine power feeder requirements
Factory-Ready Kit Integration
Can be combined with other Amphenol CIT products into kits that facilitate assembly on the factory floor
