Yueqing Naza Electric Power Technology Co., Ltd. is a specialized enterprise dedicated to the research, development, manufacturing, and sales of high and low voltage electrical equipment and complete electrical systems.
The product equipped the HV load switch and HV fuse in transformer oil .It has common box or separate box with transformer body. Oil tank is enclosed sealed with oil temperature gauge, oil level indicator, pressure gauge , pressure relief valve ,drain oil valve etc to monitor the transformer working conditions.The product has loop feed ,radial feed & power supply type.In order to make this product more suitable for the actual requirements of power grid , we have also introduced plug-in type dry type fuse which fusing do not affect the transformer oil. According to the complexity of low voltage outgoing requirements,YB27 enclosure has standard type, intensive and comprehensive type to make user choice more economic & flexible.
Outdoor Compact d substation consists of high voltage switchgear, transformer and low voltage power distribution device to connect toghter , Compact d substation is divided into three functional compartments (high voltage room, transformer room and low-voltage chamber), high and low voltage chamber functions completely.
