amorphous alloy core is divided into several categories:three phase Oil-immersed amorphous alloy distribution transformer core,single phase Oil-immersed amorphous alloy distribution transformer core,underground amorphous alloy distribution transformer core,underground amorphous alloy street lamp transformer core,amorphous alloy Padmounted transformer core,separating box combined type amorphous alloy distribution transformer core,three phase dry amorphous alloy distribution transformer core.
Product feature
1. Transformers are small and lightweight, reducing direct material costs
2. Transformers can be equipped easily and fast,the production capacity is greatly improved
3. Low noise
4. Compared with the same capacity and voltage grade silicon steel transformer,its No-load loss reduce 70%-80%,No-load current reduce about 75%,have good performance in energy saving.
First,material:1K101 amorphous ribbon
Second,Applicable magnetic flux density:
