Note: Prime Power (PRP) means the set can run continuously for 24 h under variable load, with 10% overload permitted for 1 h in every 12 h (ISO8528.PRP). Standby Power (ESP) means the set is not permitted to run with overload; when running continuously the rating is reduced by 10% (ISO8528.ESP). The above data is for reference only and is subject to change without notice.

Zhonggao Mobile Diesel Generator Sets

8–1200 kW 1500 RPM 400V

Mobile diesel generator sets cover 8–1200 kW with high mobility and fast deployment, suited to outdoor infrastructure, field work and emergency power where supply conditions are limited. Mobile power vehicles are built on state-approved vehicle models, with shock-absorbing and heat-insulating mounts between the set and the tractor, optional cabin noise-reduction treatment to meet environmental requirements, optional cable racks and winches, and four mechanical or hydraulic supports under the chassis. Mobile trailers feature a silent enclosure, single- or double-axle leaf-spring suspension, a reserved wheeled towing device with adjustable drawbar height and 60–90° turning angle, service and mechanical parking brakes, and a speed limit of 25–35 km/h. Noise level: 65–80 dBA @ 7 m.

Dual-Power Automatic Transfer System (ATS)

Dual-Power Automatic Transfer System (ATS)

  • Purpose: fully automatic transfer between two power sources (mains/mains, mains/generator, generator/generator) to guarantee continuous supply.
  • Typical workflow: in standby the control system continuously monitors the mains; after a mains failure it confirms within 5 seconds and starts the generator set, then issues a transfer command to the ATS (sold separately) and the load is switched to the generator — the whole process takes less than 12 seconds. When the mains recovers, the system confirms after a 30-second delay, issues the transfer command, and the ATS cabinet switches back to mains; the set then idles for 180 seconds to cool down and stops automatically into standby.
  • Voltage range: 400 VAC / 50 Hz; capacity range: 63 A – 6300 A.
  • Safety: fully automatic operation with mechanical and electrical double interlocking.
  • Advantages: fast transfer without manual intervention, completed within 5 seconds; eliminates operator-error faults.
Generator Paralleling System

Generator Paralleling System

  • Supports parallel operation of two or more generator sets to increase supply capacity.
  • Automatic circuit breakers provide short-circuit instantaneous and overload long-time-delay protection.
  • The Zhonggao GC6510 series digital paralleling control system achieves stepless speed and voltage regulation.
  • The digital paralleling system shares reactive and active power more accurately; the integrated set controller simplifies operation.
  • A J1939 interface communicates with a wide range of electronic engines; an RS485 / 232C interface provides the "four-remote" functions for the generator sets.
  • Can operate in parallel with the mains in different modes.
Control Systems

Control Systems

  • Optional Deep Sea or SmartGen controllers allow the user to start and stop the generator and to transfer load manually or automatically, with system parameters shown on an LCD display.
  • The controller monitors engine status and fault conditions, shuts the engine down automatically and shows precise fault information on the panel LCD.
  • Features include true-RMS voltage monitoring, electrical measurement, multiple communications (RS485 or RS232, including GSM/SMS), synchronization checking and auto-synchronization, and load sharing/control.
  • When connected to the ECU, electronic engine parameters and diagnostic data are available; the RS485 interface with MODBUS protocol provides the "three-remote" functions.
  • A rubber seal between the enclosure and the control panel gives IP65 water resistance.
Machine-Room Environmental Engineering

Machine-Room Environmental Engineering

  • The machine-room environmental noise-reduction solution suits sites with noise and emission requirements. Targeting the various noise sources and exhaust gases produced by the set, it treats noise at different frequencies and reduces exhaust blackness to meet national standards, without affecting room ventilation or set performance.
  • Scope: intake silencer system, exhaust-air silencer system, exhaust-gas silencer system, exhaust-gas purification unit, suspended acoustic wall and fire-rated soundproof door.
Soundproof Diesel Generator Sets

Soundproof Diesel Generator Sets

  • Built from standard 20 ft or 40 ft containers, making the unit flexible and convenient to deploy.
  • Sound-absorbing cotton and perforated metal panels are laid around the enclosure and on the ceiling.
  • Built-in industrial silencer, compact structure, effective noise reduction.
  • Noise is effectively controlled within 60.3–45 dB(A) at 7 m.
  • New materials and advanced manufacturing processes; the ventilation system follows the 3C design standard.
  • A residential-type exhaust silencer greatly reduces engine exhaust noise.
  • Three service doors on both sides of the enclosure plus an inspection window for the control panel.
  • A base-frame integrated fuel tank can be designed in.
