Manufacture Features:
High mechanical character,safe operation.
Low noise, small,easy installation and maintenance-free.
high levels of insulation, low partial lead.
fire-retardant,moisture-proof,extreme resistance to heat shock.
 
Usage:
The technology of transformer notable for its energy-saving effect, good performance and broad applicability to become mainstream in the development of electric drive direction .
Technology for transformer is related to electrical, power electronic technology, microelectronic technology, information and control a number of disciplines. These have been widely used throughout the industry
The direct application of dry-type transformer for high-voltage transformer provides the core components-the isolation power supply, which directly determines the performance of frequency convertor.
The grade for product’s voltage include 3kv 6kv and 10kv as well as a dedicated submersible pump oil used in 1600~2400v, and the frequency is divided into 50Hz. 60Hz. According to transformer capacity, it can be divided into 9 edges, 12 side, 15 side, 18 side and 27 side, the shift range of windings, the whole product is divided into two main categories: energy-efficient and high-precision, the conventional common type.
