Abstract: An electric switching device with insulating parts of mouldings, particularly extinguishing chamber plates in an arc extinguishing chamber, such mouldings being formed of resin binder reinforced with fiber material which is at least primarily fibers of polyvinyl alcohol or acetalised polyvinyl alcohol. The binder is an unsaturated resin converted into polymerised form.

Abstract: In an electrical switching device which includes insulating parts subjected to the influence of electric arcs, the insulating parts are formed of mouldings having a binder which consists essentially of a mixture of a linear acrylate polymer and a monomeric acrylate compound which is polyethylene glycol dimethacrylate or a polyethylene glycol diacrylate converted into polymerized form. The binder may contain an additive resin containing ethylenically unsaturated groups in the monomeric acrylate compound in a quantity of at most 25 percent of the total weight of linear acrylate polymer, monomeric acrylate and additive resin. The binder may also contain a powdered filler or a fibrous reinforcing material.
