■Glass reinforced windings▲Glass reinforced winding(Closs section)
▲Self-extinguishing proprtyWindings of RISHO cast resin transformers are reinforced with glass fabric. And these windings are also insulated with epoxy resin. Therefore,RISHO cast resin transformers are excellent in moisture and anti-pollution property Dimensions & Weight are smaller than oil-insulatin transformers.
■High reliable insulation systemGlass reinforced windings are insulated with Vacuum casting method. And eoxy resin used for this insulation has low-viscosity property. Therefore,windings of RISHO cast resin transformers has few void inside where patrial discharge occurs.
■Self-extinguishingEpoxy resin used for insulation has self-extinguishing property. Therefore,over 9200 RISHO cast resin transformers have been installed in Public facilities, such as Hospital ,Library or School up to today.
■Suitable for outdoor cubicleEpoxy resin used for insulation has so excellent low water absorption property of 0.05 ~0.08% that RISHO cast resin transformers can be installed in cubicle of JIS C 4620 compliance.
