The optimal method for the construction of a -series low-voltage switchboard is based on the assembly of its main parts, which are repeated numbered sections 7,8,9,10,11 produced solely with moulds. In contrast to the classic method characterised in that for the construction of switch boards of plural series (1,2,3 etc series) there are used at least 3* moulds (= 1,2,3...) from which the main parts are directly produced. |
