10KV power distribution--2000KVA dry type transformer
Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and other places. Simply put, dry-type transformers are transformers in which the iron core and windings are not immersed in insulating oil. Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When naturally air cooled, the transformer can run continuously for a long time under rated capacity. When forced air cooling, the transformer output capacity can be increased by 50%. It is suitable for intermittent overload operation or emergency accident overload operation; due to overload and load voltage increase during overload, it is in non-economic operation state, so it should not be in continuous continuous overload operation.
Dry-type transformers and oil-immersed transformers are the two most used transformers. Compared with oil-immersed transformers, dry-type transformers have better fire performance and are used in places with high fire protection requirements, such as hospitals, airports, stations, etc. The location, but relatively high price, has certain requirements for the environment, such as not too humid, not too much dust and dirt. In addition, dry-type transformers are less mature than oil-immersed transformers.

The safe operation of the dry-type transformer and its service life depend to a large extent on the safe reliability of the transformer winding insulation.
SMD Piezoelectric Buzzers are generally smaller than pin type Piezoelectric Buzzers. They are optimized for small devices such as blood glucose meter, clinical/forehead thermometers, smart glasses, and portable terminals.
From product designing, purchasing and testing, every step is controlled strictly by our QC staffs in order to make sure the perfect quality of our products. Currently, over 70% products are exported to US. South East Asia and Europe.
