YB Series Cubicle-type Substation

YB Series Cubicle-type Substation Product Description Summary
The three-phase oil-immersed distributing transformer applies new type insulating structure and makes short-circuit resistance strong. The iron core is made of high-quality cold-rolled silicon-steel plate. High-voltage winding group is made up of high-quality oxygen-free copper lines and it adopts multilayered drum type structure. All fasteners have been processed with special treatment to prevent them from loosening.
Reliable Structure
Spiral loops with longitudinal oil path to produce a better interior cooling effect;
Improve the effectual support of the loop’s terminal face to strengthen the anti-short circuit electricity capability;
New suspending structure and instrument-positioning frames to guarantee that the long distance transport and movement will be more reliable. Excellent Materials
Oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and the electric performance is better.
High-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
High-quality wooden laminating insulation pieces, which won’t split or move even under the influence of short circuit.
Thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.
High-quality rubber sealing material, which can prevent the transformers form aging or leakage.

Good Technology
Compare with S7 series product, S9 series product reduces the no-load loss by 10%, load loss by 24% and no-load electric current by 46%; as a result, the operating cost will drop by 19%. Improved from S9 series product, S11 series product reduces the no-load loss by 20%; no-load electric current by 70%85%; average temperature by 10K; noise level by 2-4db; and double the products’ service life. Even under 20% overloads, it can also work for a long period of time.   YB series cubicle type substation   Main functions and features   The product consists of HV distribution unit ,transformer ,and LV distribution unit and is divided into HV chamber ,transformer chamber and LV,the LV chamber has comp;ete functions,it with HXGN 10 ring main unit formsthe primary supply systom,may be arranged into several supplymodes ring main supply ,terminal supply and dual source supply and also may be [rovided with HV metering elements to meet requirments on HV metering.model s9 s11 and other low loss oil immersed transformer or dry transformers else may be selected /the transformer chamber is designed to have automatic forced air cooling system and lighting system.theLV chamber can constitue user required power supply schemes in a panel typr or cabiner type structure ,provide several functions power  distribution ,lighting distrebution reactive power compensation,and metering of electrical power to meet users different requirements,and facilitate supply management and improve power supply quality.       Application if products   Its product have following chatacters serialization,modularization,multiple functions,complete facility ,small volum,light weight and good looking ,they meet the requirment of IEC1330 standard and applicable to city public distribution ,street lamp power supply,as well as power consumption in industrial mineral enterprises,high rises,resodemtoa; areas.oil files.jetty and site construction.
