Product overview
Shanghai Qi He Hui Aviation Technology Co.’s G7 Tethered Power System provides tethered electrical power for UAV integration through a tethered box, cable and onboard power supply. The box measures 450x371x212.5mm and weighs 16Kg. It accepts 190--240VAC, with single-phase 220VAC and 50/60Hz specified, and delivers 200--750VDC with a factory setting of 750VDC. Its rated power is 7KW, with an 8KW peak. A touchscreen displays voltage, current, power, temperature, cable status and working status.
The standard cable options are 55/110m, with custom lengths available upon request. The 3.3mm tether weighs 18g/m and carries a 9A current specification. Its construction combines a multi-strand silver-plated steel wire conductor, composite fluoroplastic insulation, high-temperature Teflon insulation and Kevlar reinforcement. Electrical and mechanical specifications include insulation strength ≥3000VDC without breakdown for 1 min, tensile strength of 30Kg and ≥1000 repeated retraction cycles. These cable characteristics accompany the system’s separate ground and onboard power components.
Onboard integration requires space for a 196/149/52.5mm power supply weighing 1.3Kg. This unit has an 800--1000VDC input, a 50/59VDC output and a power specification of 6KW. External leads provide the electrical interface, while pre-drilled M3 threaded holes provide mounting points. Custom interfaces and mounting options are available upon request. The onboard supply specifications also give a takeoff-weight range of 15--30Kg, placing that figure in the aircraft integration context.
