Before we start introducing our new product range, please allow us to give a short overview of moulded insulation parts currently available in the market.
Regrettably, it is quite evident that insulating parts and products such as angle rings, snout (chimney) segments and cylinders are at present mainly available made of standard PSP pressboards suited for the thermal class of just 105 °C.
Probably not everyone is aware that in practice, this circumstance is a limiting factor for the transformer industry in designing an extended range of power transformers that could operate at higher temperatures. With regard to the higher thermal classes for 120 °C, 130 °C, 140 °C, 155 °C or 180 °C of the solid insulating product as per IEC 60076-14, this simply means that more complicated formed products for these temperatures do not exist in the market so far.
It goes without saying that the lack of availability of such products prevents a progressive design development of power transformers.
Due to this situation, we – company Schweizer in cooperation with company Isotek, have identified this challenge and set ourselves to develop a new, innovative range of moulded insulating products that comply with all temperature classes as per IEC 60076-14. This even more as by observing the entire energy sector, a change in all branches is recognisable, which is also reflected by increased demand for such innovative insulationproducts.
In general, it is evident that energy production, supply and management is becoming more and more complex. Consequently, utilities all over the world and Europe are faced with much higher requirements than in the past. Decentralised energy production, for instance, is a huge challenge and necessitates intelligent systems, which consist of energy storage, grid management, new infrastructure, digitalisation for connecting E-Mobility, Industrial and private consumers in a smart and flexible way. Consequently, new energy management systems specifications of existing transformer designs have to be adjusted to cope with the new requirements.
