Product Introduction
SCOTECH delivered 3 units of 1000 KVA indoor three phase dry type transformers to South Africa in July 2019, they are dual secondary voltage transformer, the primary voltage is 11kv, the secondary side have 2 of 0.33kv voltage（LV1@500KVA, LV2@500KVA）the cooling is ANAF, the vector group is Yy0d11. The resin cast dry type transformers is mainly composed of an iron core and a coil poured by epoxy resin. An insulating cylinder is placed between the high and low voltage coils to increase electrical insulation, and the coil is supported and restrained by a cushion block. The fasteners connected with the parts have anti-loose performance. Our 1000 KVA 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!

Cast Coil：
In the cast coil design, the coils are solidly cast in resin under a vacuum in a mold. Winding processes controlled by advanced electronics also ensure even distribution and high level of precision. The cast coil transformers are reliable, have a high short circuit withstands, and can be exposed to extreme conditions with minimal maintenance. They are used inside buildings and tunnels, on ships, offshore platforms and cranes, food-processing plant, nuclear plants and mining industry.

Dry type Transformers – Classes of insulation
Dry-type transformers are available in three general classes of insulation. The main features of insulation are to provide dielectric strength and to be able to withstand certain thermal limits. Insulation classes are:
1、220°C (Class R).
2、180°C (Class H),
3、155°C (Class F).
4、130°C (Class B).
