  • Patent number: 10283292
    Abstract: The embodiment of the present disclosure provides a cutout which can comprise a top contact assembly being capable of electrically coupled with a first electric cable; a bottom contact assembly being capable of electrically coupled with a second electric cable; an insulator assembly secured to the top contact assembly in a first end thereof, and secured to the bottom assembly in a second end thereof opposite to the first end; and a tube assembly having a fuselink placed therein for conducting electricity between the top contact assembly and a bottom contact assembly. The bottom contact assembly has a bottom contact member which is capable of electrically coupled with the second electrical cable at one end thereof, and removeably coupled with the tube assembly at the other end thereof, such that a current path is formed from the second electrical cable to the tube assembly via the bottom contact member.

  • Patent number: 8683753
    Abstract: The subject of the invention is an enclosure for secondary distribution modular switchgears, applicable in protecting switchgears both against adverse weather conditions and against unauthorized inspections of high, medium and low voltage switch gear, and also against accidental access by unauthorized persons, or by wild animals and birds. The inventive enclosure containing a base-frame (3) to which the enclosure walls are attached and which is provided with a roof cover is characterized in that the base frame (3) is formed by a metal truss and contains two extreme base-frame modules, the left one (20) and the right one (23,) and at least one middle module (21 and/or (22) which are connected with one another by means of a pair of permanent connections formed by a socket (27a) and a prong (27b) and fastening and earthing plates (28a, 28b).
