电缆压接影响因素与性能试验分析

Analysis of Influencing Factors and Performance Testing of Cable Crimping

针对电缆施工中电缆接头处事故多发的问题,分析了压接力、压接顺序、压接模具宽度、压痕相位、压痕数量、施力方式等影响电缆压接质量的因素。在此基础上,提出了一种电缆压接性能试验方法,并设计了配套试验平台。这一试验平台以气液增压型液压机为施力装置,进行电缆压接性能试验。介绍了电缆压接性能试验的具体流程,并对试验数据进行了分析。

Aiming at the problem of frequent accidents at the cable joints during cable construction,the factors that affect the quality of cable crimping,such as crimping force,crimping sequence,crimping die width,indentation phase,indentation quantity,force-applying method were analyzed.On this basis,a cable crimping performance test method was proposed,and a supporting test platform was designed.This test platform uses a gas-liquid pressurized hydraulic press as a force-applying device to perform cable crimping performance tests.The specific process of the cable crimping performance test was introduced,and the test data was analyzed.
