Description
Product introduction:※overview ( low loss type three-phase dry type safety isolating transformer ( H in 180℃insulation grade )
The transformer is a variety of power and electrical equipment in the main part, an isolation transformer is composed of a cylinder winding and laminated core, core adopts a new quality of high silicon steel sheets stacking, sloping seam. The company used advanced production technology, imports of Spain winding machine and a full set of vacuum pressure impregnation equipment; winding adopts a bodiless whole column winding method; for transformer vacuum paint dipping, making the transformer insulation level to F or H. Transformer output and input voltage can be designed according to customer demand. A single-phase, three-phase or multiple input and output specifications.
※transformer material description:
①iron core
A new high quality silicon steel sheet, the main material for the 0.35 thickness H18, H14, H12, Z11 high quality silicon steel sheet, according to the requirements of rooms and use conditions, choose the most suitable material, so that the performance of the transformer design to achieve the best. ( conventional materials for the new high quality silicon steel sheet ).
②wire
Using PEW, UEW, EIW, SEIW, FEAI enameled wire, glass envelope, temperature-resistant grade F ( 155 ℃), H ( 180 ℃), HC ( 200 ℃), C ( 220 ℃). ( normal temperature rating of class H 180 ℃).
The insulating material
The high temperature resistant insulating paper for insulating material, high temperature insulation, flame retardant and high wet multiple performance.
The terminal blocks
