SG(B)10 series three-phase open dry transformer

Transformer Opening Dry Type Transformer (SGB10)

1.Product Introduction of SG(B)10 series three-phase open dry transformer

SG(B)10 series three-phase open dry transformer by the strict control of material, optimized design, reasonable processing, SG(B)10 series three-phase open dry transformer passed CTQC (certificate test of quality control) by State Transformer Quality Supervision& Inspection Center. To get reasonable structure and artistic appearance, NOMEX paper from DVPONT Co. And advanced VPI (vacuum pressure impregnation) technology are both used for the products.
According to the user's needs, can be equipped with ordinary steel plate, aluminum alloy or stainless steel shell, protection grade has IP20、IP23 and other optional, can be configured according to the user's needs high and low voltage busbar access line connection.

2.Product Parameter (Specification) of SGB10 series dry type transformer

(1).Environmental protection:
High quality H grade insulation material is used the product, there is no emission of hazardous gases under high temperature.
Owing to the opening winding, it is convenient to take copper back for recycling after the service life.
(2). Reliable insulation system:
NOMEX paper and ET-90 series H grade resin is chosen as basic insulation system, optimized design makes insulation system 180 degrees centigrade - 220 degrees centigrade, which is safe, steady and reliable under high temperature.
(3). Advanced processing technology:
Adopting VPI technology and curing process under the high temperature, the lacquer film is bright and even, no cracking, the partial discharge is less than 5PC, with low noise.
(4). Overload capacity:
H grade Nomex paper is used for insulation of winding in opening structure. Its dissipation of heat is faster and temperature rise is even, which shows higher overload capability.
(5). Stronger withstanding short-circuit capability:
VPI process is carried out for H. V. &L. V. Coils and pre-pressing device such as disc spring and silicon rubber is put on the end of coils to strengthen the mechanical strength for both coils and product, which improves its withstanding short-circuit capability.
(6). Weatherproof:
The whole product is coated with H grade insulation lacquer twice. Lacquer film has the good adhesion, mechanical strength and insulation performance without cracking. Therefore, it is weatherproof such as moisture, fog and dust, particularly in serious pollution.
