S11-M type oil-immersed distribution transformer PF134

The S–M series three-phase oil immersed distribution transformer belongs to state hih-tech new product it is developedbased on new type S9 series product’s mechanism design.the design idea is mainly aimed at heightening product’s reliabilitand performance,design reportedly adjusts some coeficient of losses and mechanism according to new S9 product.so as tohave loss design up to measured value’meanwhile the optimizing design properly fix ratio of cooper to iron.in order todecrease material cost and have structure more proper.

Iron core
Adopt super–performance silicon steel sheet with hioh conductive-maanet and low oss properties.which could reduce nooad loss.
Core and winding assembly
Whole series of high-volt winding adopts multi-laver structure. among the products 500kVA or lower the low-volt winding ismulti-layer type.

Structure
The low-volt of 630kVA or higher product adopts new type spiral type. the assembling of core and winding assembly sums upmature experience of new S9 distribution Transformer,it could shape one solid integer after assembling,so as to ensure thatproduct owns well electric performance and mechanical strength at the time of sudden short.

This series product possesses pan-seal structure which guarantees isolation between external air and transformer’s oil.Prevents oil aging and heightens operating reliability of transformer. The oil tank adopts corrugated oil tank.open one lonahole both at upper and lower part of box wall.for accelerating oi’s circulation on corrugated plate.This kind of oil tank ownssimple technology and high mechanical strenath, it has heightened oils fluidity and heat-radiation capability,its welding efect isgood and not apt to leak
