Abstract :
Adopting insulated conductors and compact configuration has become the tendency in the renovation of distribution network in China. Advantages of compact configuration are discussed. Superiority of compact configuration against lightning protection has been analyzed. The reason that breakage faults occurred on compact distribution tine with polymeric spacer is discussed. It is due to the bad pollution flashover performance of the polymeric spacer cast with polycarbonate. Polycarbonate Is not suitable for outdoor Insulation. A new triangle composite spacer, which Is suitable for heavy pollution areas, Is designed to prevent breakage faults caused by leakage current. 28 cm is chosen as phase spacing. The application effects of the developed composite spacers are very good.
