Adopting covered conductors and compact configuration has become the tendency in the renovation of distribution network in China. Advantages of compact configuration are discussed in this paper, which can further save the passage of distribution line, and can easily realize multiple lines in a pole. The movement process of phase conductors is analyzed by the Chord Forced Equation of the mechanical theory to obtain the relationship between the phase spacing of triangle spacer and the span between two neighboring spacers. The suitable phase spacing and spacer span are presented for polymeric and composite spacers. The superiority of compact configuration against lightning protection comparing with traditional distribution lines was analyzed.
