Product introduction
ZGS11 series combined power distribution transformers is a new device (also known as the American box changed),the company is by the introduction of foreign advanced technology and design concepts,with domestic situation,specifically for the power distribution networks design of new products.Combined transformers especially for
the city power grid load center,residential center,hospital,school,airport,stationsect,reduce losses and improve the quality of power supply.
Product features
1.Small size,reasonable and compact structure;
2.Sealed fuel tank,full insulation design,safe and reliable operation;
3.High overload capacity,superior performance and resistance to sudden short-circuit;
4.Ring network and terminal power supply can be used,
5.Convenient operation and reliable power supply:
6.Energy saving,low loss,loss value is not higher than the new S9;
7.Impact performance;
8.Cable Connector No.200A loads current operational,long mechanical and electrical life life.
