Factory Power supply step down 10kv transformer 250kva
The oil immersed power distribution transformer is famouse for low loss, low noise, strong protection for thunder and lighting, well anti-shortcut capacity and fine appearance etc. All our transformer has passed the test by National Mechanical & Industrial Bureau and National Power Company. The transformer is mainly used in power network, and the projects of power distribution. 2
00kv transformer
The series transformer adopt silicon steel sheet iron core which is made of excellent low loss crystal granule. it have the merit of low no-load loss, small no-load current and low noise.
