Barramento duplo
Um quadro de 10 kV com dois barramentos, cada um dividido em seção I e seção II por um disjuntor de seção. Duas entradas, um acoplamento entre os barramentos, cada vão ligado aos dois barramentos por duas seccionadoras e quatro vãos de saída.
Grátis para usar e modificar nos seus próprios projetos, inclusive comerciais. O ZIP traz o desenho de exemplo, um modelo, uma tabela de estilos de plotagem e um README; não precisa de nenhum add-in. Os dados do desenho são inventados, então ele não serve para projeto nem para obra. Fornecido como está, sem garantia. Library terms (CXL-1.0)
