摘　　要：为了研究电力复合脂摩擦系数对导线握力的影响,对不同类型电力复合脂的摩擦系数进行了测试,并开展了涂不同类型电力复合脂导线握力试验。试验结果表明:不同类型电力复合脂的摩擦系数是不同的。当电力复合脂的摩擦系数大于0.08时,电力复合脂对导线的握力基本没有影响,导线的破坏特征为铝线断裂。当电力复合脂的摩擦系数小于0.015时,电力复合脂对大截面导线的握力有明显降低,导线的破坏特征为铝线滑出。Friction coefficient test of the different categories electrical joint compound, and holding force test of conductor with different categories electrical joint compound were conducted to reveal the influence of friction coefficient for electrical joint compound on holding force of conductor. The test results show that the friction coefficient of different types of electrical joint compound is different. The electrical joint compound, which the friction coefficient is greater than 0.08, exerts little effect on holding force of conductor, and the failure characteristics of the conductor is aluminium wire fracture. The electrical joint compound, which the friction coefficient is less than 0.015, can significantly reduce holding force of conductor , and the failure characteristics of conductor is aluminium wire sliding out.
