W*D*H(mm)		 Weight(kg) Reactor type
35 8.0～21.0 14500*1800*2100 9550～10200 Air core reactor
22.0～42.0 26200*1800*2100 15580～19200 Air core reactor
43.0～70.0 47800*1800*2100 27000～32000 Air core reactor
71.0～80.0 52400*1800*2100 36000～72000 Air core reactor


Water cooling type
Voltage class(kV) Rated capacity(Mvar) Dimension
W*D*H(mm)		 Weight(kg) Reactor type
35 5.0～50.0 7400*7900*2600 9000～14000 Air core reactor
51.0～85.0 11500*7900*2600 15800～24000 Air core reactor
86.0～100.0 16000*7400*2600 18000～28000 Air core reactor

Note:
1. Capacity (Mvar) refers to the rated regulation capacity within the dynamic regulation range from inductive reactive power to capacitive reactive power.
2. The air core reactor is used for the equipment, and there is no cabinet, so the placement space needs to be planned separately.
3. The above dimensions are for reference only. The company reserves the right to upgrade and improve the products. The product dimensions are subject to change without notice.
 
System Performance
cooling method

01 Forced air cooling
The intelligent temperature control system is adopted for air cooling and heat dissipation: the frequency conversion control technology is used for the heat dissipation fan, and the speed of the heat dissipation fan is controlled according to the equipment capacity, radiator temperature and ambient temperature, so as to control the inlet air volume, so as to achieve energy conservation and noise reduction, especially when the capacity is small, the effect is more obvious.

02 Air water cooling
The hot air caused by the heating of the equipment returns to the room after passing through the outdoor water-cooled heat exchange system to form a hot air cold air circulation system to realize the purpose of equipment heat dissipation. The circulating water used by the outdoor water cooling and heat exchange system can borrow the external water source on the site, establish water tower and other ways, which is suitable for the site with harsh environment.

03 Wind water cooling
In harsh environments such as high sand, high humidity, high salt fog, high corrosion and high condensation, as well as occasions with high noise requirements, conventional air-cooled heat dissipation can’t well meet the environmental requirements of the site, but the use of water-cooled heat dissipation can better meet the needs of the site.
