EPOXY RESINS FOR TRANSFORMER
RE 8293
The resin RE 8293 is made with epoxy resins, bisphenol A and special mineral powders formulated for encapsulation of power or measure transformers. It is used with the vacuum casting method and the working of the mixture is easy and rational. It is supplied in two components that have to be mixed in predetermined proportions without the addition of accelerators and powders. The resin features low viscosity and low temperatures of working.

RE 9410
The resin RE 8293 is made with epoxy resins and bisphenol A. It is not charged and it has been formulated for encapsulation of power or measure transformer. It is used with vacuum casting method and the working of mixture is easy and rational. Once it has been hardened it has high mechanical, thermic and electrical resistance and very good thermic shock and ageing resistance. It is supplied in two components that have to be mixed in predetermined proportions without the addition of accelerators and powders. The resin features a low viscosity and low temperature of working that permit working time enough long.
