Embodiment Construction
[0024] Reference will now be made in detail to various embodiments and aspects of the invention. Each embodiment and each aspect is offered by way of explanation, not limitation. For example, features illustrated or described as part of one embodiment or aspect can be used on or in conjunction with any other embodiment or aspect to yield a further embodiment or aspect. This disclosure is intended to cover any such combinations and variations.
[0025] According to one embodiment there is provided the use of an epoxy resin composition in outdoor applications or medium and high voltage applications of electrical insulators. The epoxy resin composition comprises an aliphatic epoxy resin and a catalyst system. The catalyst system is present in the epoxy resin composition in an amount from about 0.5 phr to about 5 phr (parts per hundred resin). The catalyst system comprises BX 3 At least one of an amine complex and a blocked superacid. According to embodiments described herein...

Abstract
The use of an epoxy resin composition in an outdoor application and / or a high voltage application of an electrical insulation is described. The epoxy resin composition includes an aliphatic epoxy resin; and a catalyst system. The catalyst system is present in a content of 0.5 -5 phr in the epoxy composition. The catalyst system includes at least one of the group consisting of: BX amine complex andblocked super acid. The epoxy resin composition is substantially anhydride-free. Further, a power product including insulation is described. The insulation includes a hydrophobic, cycloaliphatic epoxy resin; and a catalyst system. The catalyst system is present in a content of 0.5 -5 phr in the epoxy composition. The catalyst system includes at least one of the group consisting of: BX amine complex and blocked super acid. The epoxy resin composition is substantially anhydride-free.
Description
technical field [0001] The present disclosure relates to the use of an epoxy resin composition in an electrical insulator for insulating an electrical product, and to an electrical product comprising an insulator having the epoxy resin composition. Furthermore, the present disclosure relates to an electrical product for medium and / or high voltage electrical power transmission or distribution, said electrical product comprising a conductor surrounded by an electrical insulating material comprising said epoxy resin composition. Background technique [0002] Epoxy resins can be cured by several reactions, for example, copolymerization or homopolymerization. For copolymerization, hardeners are used. For example, the use of anhydride hardeners for curing epoxy resins is known in the literature, including several low anhydride content (5-10% by weight) concepts as well as epoxy resins with grafted anhydride groups. Curing of epoxy resins also occurs in the presence of alternativ...
