GP 270 V DC
Ground power supply cable
Marking example: SAB Bröckskes · D-Viersen · GP 270V DC 8x8AWG+8x8 AWG+2x3x14AWG 3400-0503 CE
Application
Our GP 270 V DC cable in 8 × 8 AWG + 8 × 8 AWG + 2 × 3 × 14 AWG is specifically designed for the ground power supply of F‑35 fighter jets and ensures reliable energy delivery to the aircraft systems. Its dual-jacket design with a red inner and yellow outer jacket provides a clear abrasion indicator, facilitates replacement planning, and enhances the safety of ground personnel. The cable meets the highest requirements for mechanical strength, chemical resistance, hydrolysis and microbial resistance, is halogen-free, and withstands extreme temperature ranges from -50 °C to +110 °C.
With minimal voltage drop (DC resistance max. 7.98 Ω/km for 2.5 mm²) and test voltages of 3–5.5 kV AC, it guarantees safe operation even under extreme conditions. Thus, our GP 270 V DC cable offers a durable, low-maintenance, and highly reliable solution for the demanding ground power supply of modern military aircraft.
