Power Distribution Equipment

FUNCTION Transformer cooler control cabinet is an indispensable auxiliary system of oil immersed transformer and provides optimal control to the whole transformer cooling system, lowering the transformer body temperature, saving energy and prolonging transformer service life.
SPECIFICATIONS There are six parameters needed to specify the transformer cooler control cabinet
1. Control cooler number and fan number
2. Control cooler or fan power, rated current and oil circulation method
3. Control power
4. Control voltage grade
5.Communication specifications (if communication function is needed): RS232,RS485,Ethernet
6. Cabinet ventilation pattern
RANGE Control cooler number: 2-10sets, fan number:2-30sets
Control power: DC110V+10% or DC220V+10% or AC220V+10%
IP grade:IP55
