The Chinese DFH-5 bus was developed for the next generation large GEO telecommunications and earth observation satellites. It used many new technologies: electric propulsion, networked heat pipes, a deployable radiator, a 2-dimension semi-rigid solar wing, unified system propulsion management, a new-generation power controller, and improved integrated electronics. It's greater launch mass was matched to the CZ-5 launch vehicle and first launch would await the availability of the new booster.
Characteristics were as follows:
Launch Mass: 6500-9000 kg
Dry Mass: 1800-2750 kg
Satellite Power: 10,000-30,000 W
Payload Mass: 1200-2200 kg
Payload Power: 4.000-220.00 Ww
Lifetime: 12-15 years (depending on configuration)
