6.Certifications And Workshop Of Product 7.Parts Of Product

Core	1	Power transformer  core is made of high-permeable grain-orientated top quality cold-rolled silicon sheet
	2	The material is cut with advanced Germany Geoge GmbH automatic shear line with the cut burrs controlled within 0.02mm.
	3	Power transformer  silicon sheet fabrication adopts “no-upper yoke-lapped’ technology and all lapped joints of the silicon sheet are 45 full-miters
	4	Effectively improves no-load performance and reduces noises.

 

Coil	1	The high-voltage(HV) coil adopts an interleaved-continuous structure to improve the voltage characteristics under impact voltage and make voltage evenly distributed.
	2	All stays and pads are chamfered to keep highly reliable insulation.
Oil tank and accessories	1	Power transformer tank wall adopts wide steel sheet
	2	Which will be folded into corrugated structure without splicing
	3	In this way welds aredecreased and mechanical strength is enhanced
	4	The corrugated wall has diverging effect, and thus plays arole in decrease of noise.
