YB箱变.pdf

This product was developed through absorbing foreign latest technology and on basis of domestic condition, the whole equipment has small size, easy to install and maintain, low noise, low loss, anti-theft, high overloading capacity, full protection and etc, suit to work in new living zone, green zone, park, station, hotel, building site, airport and etc.

YB11-12 Series prefabricated substation, is suitable for operating in 10KV, RMU power supply system, twin power supply system or termination power supply system, use as power transformation, metering, reactive compensation, and protection. 

Product advantages

■ Full insulation, complete sealing, maintenance almost not needed, protect the safety of personnel,

■ Compact structure, the volume is just 1/3-1/5 of European style substation with same capacity, lower height,

■ It can adopt the structure of splitting cabins, to avoid the transformer oil being polluted;

■ High voltage side uses dual fuse of full range protected type, further saving cost;

■ RMU or termination switchgears can be selected, at emergency case the cable connector can be pulled out with 200A loading current;

■ The kiosk body made of beehive type compound plate with dual clamping layers, temperature separated and radiating; 

■ Low voltage side install electronic phase failure protector, when abnormal voltage happen, it can trip the general switch rapidly;

■ Oil-immersed type load switch or SF6 load switch is used in high voltage side. The motor operated mechanism can be replaced for automatic control in future

■ Distribution transformer may be S9 series or S11 series with better performances 。
