Small diesel generator set is a diesel-fuelled internal combustion engine driven alternator small power generation equipment, power range is usually between 7-30kW, by the diesel engine, generator, control box and fuel tanks and other core components, suitable for emergency power supply or mobile scene.
The units are usually air-cooled, and some models are equipped with water-cooled cooling structure to improve efficiency, and the silent design can control the noise at 65-73dB. The structure integrates shock-absorbing spring base, universal wheels and handles to support mobile deployment. Standard features include voltage/current monitoring, battery starter, and optional ATS automatic switching and remote start. Technical improvements include a spiral tube cooling system with a ventilated electric fan for synergistic cooling, as well as multiple protection mechanisms such as low fuel consumption (205g/kw.h) and automatic voltage regulation [1].

LV power cable are rated up to 0.6/1 kV and mainly used in eletric distribution at the nearest and to users items , i.e.machineries, equipments, applicances, lightings,power outiests, etc. The conductors are copper or alumiinium, solid or sranded wires, can be compacted to shape round or sectored insulated cores. The size rangers from 1.5 up to 1.000sq.mm per core and a cable may comprise 1 up to 4 insulated cores. Any cable protections ay be applied , including contruction and materials for direct and fire safety.

Low Voltage cable with PVC insulated and sheath is used as power distribution and transimssion line at rated voltage 0.6/KV which can be fixed installed.

Operating Characteristc

1)The long-term working tempeture of cable should be not higher than 70 degree.

2)When core is in short-circuit (Max. 5s), the tempeture should not exceed 100 degree.

3)While installation the ambient tempeture should not be lower than o degree, and bending radius should not be less than 10 times of outer diameter.

Low voltage motors

Low voltage motors are classified primarily according to their fundamental physical differences, and secondarily, according to their purpose of use. Accordingly, we divide motors into two ranges of induction motors, four types of motors for explosive atmospheres, frequency controlled motors, most notable of which are synchronous motors, and special application motors. The last category of motors include, for example, marine motors, brake motors, and smoke extraction motors, which are based on the basic induction motor but have modifications that vary according to the purpose of use.

Their features are not further described here.

(A) Standard induction motors:

We supply two types of low voltage induction motor series: Process performance and General performance motors. The first are the most commonly chosen induction motors for demanding industrial uses. General performance motors form the basic motor series in the IE2 efficiency class.

(B) Motors for explosive atmospheres:

The low voltage motors for explosive atmospheres, or so called Ex-motors, comply fully with the ATEX directive 94/9/EC, which sets forth the mandatory duties and responsibilities of the supplier of products.

Motors for explosive atmospheres are available from the range of 0.25 kW up to 1000 kW.


(C)Frequency controlled motors:

Frequency controlled motors refer to motor series that are invariably used together with a frequency converter. This category of motors includes two types of synchronous motors, namely synchronous reluctance motors and permanent magnet motors, as well as roller table motors, high speed motors and servomotors.
