Recently, composite insulators have been increasingly employed mainly from the economic viewpoint. We have been developed new type outdoor termination with composite insulator, which can be installed horizontally on the steel tower, in order to reduce the construction cost. In this outdoor termination, SF6 gas is filled in the composite insulator and a cold shrinkable pre-molded rubber unit is applied instead of the combinational use of rubber-molded stress relief cone, epoxy resin insulator and spring unit. The application of composite insulator, SF6 gas and cold shrinkable pre-molded rubber unit lights the total weight and makes it possible to install horizontally on the tower.The composite insulator type outdoor termination for 77kV XLPE cable has already applied as commercial use and enabled to reduce the construction cost of power transmission lines. A 154kV new type outdoor termination has been developed and successfully completed the initial electrical test.This paper describes the design and performance of both 77kV and 154kV new type outdoor termination, and the follow-up survey of 77kV outdoor termination in the commercial power transmission line.
