DRY TYPE TRANSFORMERS
DRY TYPE TRANSFORMERS
(OP)
Hi Guys,
I am trying to source a Transformer company that has Type Test Certification IEC 60076-11 for a Vacuum Pressure Impregnated Insulation
in a IP65 enclosure. My clients requirement is a fully rated 1600kVA 11000/550volt no load AN operating in a ambient temparature of 50deg C
although my absorbed motor load is 20% less. I find Tailand, and China are side stepping the issue of Type tested - they mainly have encapsulated cast resin.

RE: DRY TYPE TRANSFORMERS
Make sure you pay particular attention to partial discharge levels: define maximum acceptable levels at the time of order. Measure before and after any testing, and ensure that the contract is well written in case there are problems at test.
