The diesel generator set is a kind of power generation equipment fueled by diesel, which is widely used in different fields and can achieve multiple effects.
Industrial field: In factories, mines, construction sites and other places requiring large amount of power supply, diesel generator sets are usually used as standby power supply to cope with power failure or emergency.
Commercial field: shopping malls, supermarkets, hotels, hospitals and other places often require diesel generator sets as standby power supply to ensure normal operation and medical services are not affected by power failure.
Agriculture: in rural areas or remote areas, farm irrigation, farm farm, fishing boat and other places, diesel generator sets are often used to provide stable power supply.
Meteorological disaster emergency: in case of natural disasters such as storm, typhoon and earthquake, the diesel generator set can provide emergency power for the disaster area to support disaster relief.
