Single-Phase Pad-Mounted Transformer 15-250 kVA
Single-Phase Pad-Mounted Transformer 15-250 kVA is american type combined substation with function of high voltage control, protect, power transformation and distribution. Usually used in urban and rural power distribution system .The high voltage load switch and high voltage fuse of this product are installed in the oil immersed transformer, with the two structure: in same case with the transformer and in different case with transformer.
Products Features
1.The core is kind of a wound core. The whole core is composed by three identical single frames. Each single frame is wound by several ladder shaped material strips continuously and orderly.
2.The lengths of three magnetic circuits are the same and the shortest. So no-load current of three core limb is small and three phases are balanced. Saving 15% of silicon steel than flat wound core.
3.The core is wound tightly without seams. It has the advantages of lower no-load current, smaller magnetic resistance and lower loss. It also reduces the noise level.
4.The core is wound tightly without seams. The cross section of wound core is similar to a circle. The core frame is wound by machine. Filling factor can reach 0.95~0.97
5.Rectangular material strap will be cut along the line in the picture and then will be wound. No waste, material utilization by 100%
6.Reduce 25% no-load loss and no-load current of more than 70%
7.Reduce noise level 7~10dB
8.Balanced magnetic circuit of three phases
