LONGKAI diesel generator set is usually used for the power generation of base station of telecommunications. The unit is subject to the provincial 1000KW-500KW and regional city 400KW-100KW with the general use of a short time and selected according to reserve capacity; it is generally as the common unit below the district and county 100KW. In addition to the self-starting, self-switching, self-running, self-input, self-shutdown, etc., such application is also equipped with various fault alarm and automatic protection devices.

Advantages of Product

Targeted complete products, data and programs meeting the use requirements;
Control system with AMF function can achieve automatic startup and shutdown;
ATS can be selected to achieve intelligent switching of unit / mains;
Stable performance and unit MTBF not less than 1000 hours;
The specific devices can be selected to achieve operating needs of high cold and high temperature regions;
The design and development can be made according to special customer demands;

Product Requirements

  • Working Environment
    Not more than 1000 meters above sea level;
    Operate normally from -15 ℃ to 40 ℃;
    Beyond this temperature range, the special unit can be used;
    The overloading for 1 hour by 10% can be made per 12 hours;
  • Noise Requirements
    Ultra-low noise can ensure that bank staff set their mind on the work;
    Low exhaust emissions can ensure the cleanliness of generator room;
    Noise reduction measures can be developed according to different environmental requirements;
  • Safety Measures
    The unit is equipped with grounding protection and emergency shutdown button;
    The unit can send sound and light alarm signals in the case of too low oil pressure, too high water temperature, too low water level, overload, startup failure, overspeed, short circuit, phase lack, too high voltage, voltage loss, low frequency, too low voltage of startup battery, too high voltage of startup battery, low oil level, etc.;
    Brushless permanent magnet excitation AC generator is used to improve motor starting bearing capacity and non-linear load capacity and provide immunity for the waveform distortion of mainframe stator output voltage and stronger short-circuit current withstanding capacity (usually up to 3 times of rated current for continuous 10S);
    The full automatic transfer switch cabinet can be selected according to needs;
    Unit / mains switch time is not more than 20 seconds and automatic shutdown is made after operation and cooling for 0-300s from the mains restoration;
  • Performance Guarantee

    The unit uses high-end brand engines and generators, with powerful performance;
    The unit MTBF is not less than 1000 hours;
    Optimal design and strong environmental adaptability;


The LONGKAI generator set with excellent and stable performance is integrated with the advanced design concept to ensure that the alternative power supply system can quickly provide power in case of the outage of communication base station. Through equipped RS232 or RS485 / 422 communication interfaces, it can be networked with the computer to make remote monitoring and achieve remote control, remote signaling and remote sensing so as to be fully automatic and unattended.
