Product Introduction
The 6.7 MVA dry type transformer was delivered to Vancouver, Canada in 2016, the rated power of the transformer is 6700 KVA. It is a vacuum pressure impregnated winding dry type transformer 25kv to 4.16kv, the high voltage of this dry type transformer is 25kv, the low voltage is 4.16kv. The insulation materials on wires are with H class insulation, which service life is longer than ordinary dry type transformer. Our 6.7 MVA dry type transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time.
We ensure that each one of our delivered units has undergone rigorous full acceptance testing. We provide one-package service from consulting, quoting, manufacturing, installation, commissioning, training to after sale services, our products are now operating in more than 50 counties in the world. We aim to be your most reliable supplier as well as your best partner in business!

Advantage：
1、Class H insulation
The insulation grade of H-class insulation dry-type transformer is class B, F, H, C, etc. The temperature resistance temperature of dry-type transformer is 130 ℃, 150 ℃, 180 ℃ and 220 ℃. SG (b) dry-type transformer adopts new materials and new technology of DEPONT company, and its thermal durability reaches grade H and that of some key parts reaches grade C.
2、Safety
SG(B) series products are today’s highest safety dry transformers, all insulation materials are non-combustion-supporting, self-extinguishing, non-toxic.
3、Reliability
The special coil design, process and material of SG(B) series products are the products with excellent three-proof performance, which can withstand thermal shock and never crack.
