About us:
1.Tianjin Grewin Technology Co.,ltd. has always laying great emphasis on our core business philosophy "Quality and Honesty First ".
We can manufacture EI Power Transformers.Below is our mainly products with much advantages in our market:
Custom mains transformers 50/60 Hz
|
Transformers withparticular core requirements such as size, finish, pins layout, input and output voltage. |
|
|
Where PCB does not allow the use of mains transformers encapsulated in resin we can supply air transformers with plastic shell for the protection of windings and the improvement of creepage-clearance.
|
|
|
custom transformers are manufactured according to the technical and safety requirements from clients. As an example, here you can find some of the most common features you can easily request:
|
|
|
Primary and secondary windings in separate sections
|
|
|
Encapsulation in epoxy resin or insulating varnish dipping.
|
|
|
Hot-dip tin coated phosphor bronze pins
|
|
|
Pin size: Max diameter =0,90mm ,Minimum length =4mm
|
|
|
5KV Primary to Secondary dielectric strength
|
|
|
100% tested
|
|
|
On request they can be tested to meet CEI EN61558-1(CEI 96-3) eCEI EN 61558-2-6 (CEI 96-7) safety standards. |
