Abstract
The utility model discloses an arrester insulating cylinder used for a solid insulation ring-network cabinet. The arrester insulating cylinder comprises three insulating cylinders connected together side by side. Each insulating cylinder is provided with an incoming terminal and an outgoing terminal. The incoming terminal is provided with an incoming conductor which extends into the corresponding insulating cylinder. The outgoing terminal is provided with an outgoing conductor which extends into the corresponding insulating cylinder. After the arrester insulating cylinder is assembled on the solid insulation ring-network cabinet, no exposed metal conductors exist, thereby improving antifouling ability, insulating property, and long-time running reliability of the arrester.
