"Power in Starkstrom" - the Starkstrom-Gertebau (SGB) group uses this slogan in provi-ding top performance in the field of power engineering. Our guiding principle, however, is far more than just stringing together catchwords. It sums up our corporate philosophy.It documents our position in the industry. And, above all, it represents an incentive andan obligation to fill this idea with life and power and to implement it in the form of our products and services.We offer our customers a wide spectrum of products, ranging from transformers for energy supply (power transformers, oil...

We guarantee transparency and cost-effectiveness. We are in favour of transparent offers andcost-effective solutions. This is why we take account of the costs not only for con- struction but also for operation and mainte-nance for the entire service life of the unit in question (life-cycle costing). We develop the technology. > The further development of transformer technology is a permanent challenge for us.Even in the past, SGB, as a specialist intransformers, has had a great influence on the state of technology in Germany. In order to be able to offer further outstanding achie-vements...

Further training creates competence. The main focus is on the personal aspect. People and not machines repre-sent the focus of attention of all of SGB's activities, for the usefulness of our activities for customers and staff is a centralcorporate purpose. We havemore than 1,000 well-trained, highly-motivated and loyal staff members, who form thefoundations of our outstanding achievements. One importantaspect here is individual respon-sibility, for in the final resort the implementation of corporateobjectives can only be achievedby the individuals themselves. Only a qualified team can...

Since 1960 almost 2000 power transformers have been built in Regensburg and are now working on the gridsystems of our customers. We pride ourselves on having a longstanding and close relationship with our customers who state that SGB power transformers are very reliable with a failure below 0,36 % as indicated in specialized literature. Perfectly matched Cores, winding, on-load tap changers, terminal leads and clamping structures are subject to enormous stress during the periodof operation of a transformer. It is importantthat all elements should interact smoothly and correctly. With the...

Sophisticated technology We combine high-grade materials, the latest construction elements, sophisticated manu-facturing processes and top-quality work-manship to produce perfect technology:For example, the boltless core consists ofhigh-quality, cold-rolled, grain-orientedtransformer sheets.The windings are produced using modernmachines with predefined tensile force andfixed clamping force.After predrying, several clamping operationsguarantee the strength of the winding.The drying process according to the VDmethod removes all of the moisture from the core-and-coil assembly. > Know-how pays...

Sturdy: core and winding > The iron core of our oil distribution transfor-mers is made up of cold-rolled, grain-orien- ted magnetic sheet steel using "step-lap"staggering technology. As for the winding,the tried and tested combination of LV foil winding and HV layer winding ensures idealperformance data and ideal impulse voltagedistribution. On account of the LV foil winding, axial current distribution canadjust itself as required in the foil conduc-tors. Thrust is thus largely avoided, and axial contraction forces cannot act in the foil conductor. The HV layer winding isextremely compact,...

Lahmeyer compact stations have been in the Neumark based SGB line of products since July 2000.Production is carried out in a newly build plant hall.The entire know-how as well as the responsible mem- bers of the staff from the technological and sales areaswere transferred from Piller Mechernich to SGB,Neumark. In this way, a forty-year tradition in the development, the construction and sales of metal-casedcompact stations is being successfully continued at a reliable and efficient transformer manufacturer.The solution offers the following beneficial features:ηStabilityLow weightComplete...

Thanks to their design, SGB cast resin transformers offer a number of outstanding propertieswhich make them extremely cost-effective, reliable and safe solutions, particularly in industrial plants. SGB cast resin transformers are extremely resistant to fire: the independent expertiseby the Association for the Promotion of FireProtection in Germany (Vereinigung zur Frderung des Deutschen Brandschutzese.V., VFDB) shows that ignition using simple means is practically impossible.Our cast resin transformers have all electro-dynamic forces under control. The windinginsulation of the LV foil...

Further properties of cast resin transformers are: Advantages that speak for themselves mould-based vacuum castingՕfreedom from partial discharge < 10 pc cooling-air ducts minimise temperature riseՕglass-fibre material ensures high mechanical strengthwe use epoxy resin to impregnate the glass-fibre insu-lation. The mixture is exactly tailored to meet therequirements of each transformer. Favourable installation costs: Since the fire risk is low, the transformers can be set up at the load centre. This savesinvestment and energy costs. High degree of flexibility: Neither an oil sump nor...

Components and systems for neutral-pointconnection Medium-voltage systems in Europe are large-ly operated as resonant-earthed systems.SGB offers a complete range of products for the necessary neutral-point connection:arc suppression coilsՕfixed coils, off-circuit variable tapped coilsas well as coils variable under load. The variable coils can be operated withthe fitted electronic regulators and have an automatic modeneutral electromagnetic couplers Օearthing transformersearth fault combinations consisting ofneutral electromagnetic couplers and arc suppression coilsIn particular cases the...
