This invention concerns a device for an outdoor switching apparatus of an electrical power line, the switching apparatus being enclosed within a case. The device includes a wall made of electrically conductive material capable of blocking sun rays. The device also includes a fastening assembly for fastening the wall with respect to the case in a position for blocking, at least partially, sun rays from hitting the case during day time. The fastening assembly has at least one spacer made of insulating material for spacing the wall with respect to the case, thus delimiting an air gap between the wall and the case. The device also includes at least one electrical connector for electrically connecting the wall to circuitry of the switching apparatus, located inside the case, for powering and voltage monitoring. |
