Product Description

S11 315kVA Series Three Phase Oil Immersed Distribution Transformer


Overview

Iron core:
the iron core is made by crystal grain-oriented silicon-steel sheet; GEORG cross cut shear (made in West Germany) is adopted to cut the silicon-steel sheet with a 45°joint seam;fold the sheet into a multistage roll cross-section to reduce the noise and power consumption.

Coil:
cylinder type for high voltage; cylinder type or foil type for low voltage;this can increase the ability to resist short circuit and strike; and the distribution of magnetic path is more rational.

Oil tank:
the oil tank is made by fine cold-rolled steel sheets; GEORG corrugation oil tank production-line is adopted; to meet environmental needs, then, antiseptic coating material is applied on the surface, which can meet the requirements for petroleum and chemical industry (much oil stain and many chemical substances). In addition, the corrugations not any possess heat radiation function, but also meet the requirement for oil expansion and oil contraction trader normal performance. The iso lation from air guarantees a low aging speed of oil and a long life expectancy of transformer.

Insulation structure:
oil-immersed distribution transformer adopts A-level insulation structure; high voltage coil and low voltage coil are concentric; the space between coils is cardboard sleeve small oil clearance oil partition structure.


Product specification

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.
