Abstract
In order to apply the composite pole to power transmission lines for solving the problems of lightening or polution flashover, it is necessary to test its material, electrical and mechanical characteristics. The test results in this paper are as following: the polyurethane composite can remain its insulativity somehow under the condition of damp or raining, and it can be used for pole to increase the insulation level; the composite pole for 110 kV lines is better than the normal steel tower as its phase-ground clearance is higher of 70%, and its lightning impulsive voltage increases about 75% , as well as its creepage distance of phase-ground increases about 40% in the grounding way of groundingwire extracting along the line direction and going off the tower down to the ground; the phase-ground tolerance voltage of pollution flashover is 2.5 times more than the maximum working voltage; the whole strength of pole can meet the requirements in various load conditions, and its deflection is larger than that of the steel pole. A 110 kV double circuits half-composite pole with two bases has been oprating in network for more than one year well enough.关键词
