一、产品概述
本装置又称导线受损程度试验装置，主要依据UL 486A-486B等标准要求制作，主要用于判断螺纹夹紧型的接线端子在设计和结构上是否达到了在其夹紧导线时无过度损坏导线的要求，还用于考查无螺纹接线端子是否经受得住正常使用时出现的机构应力。使用时可先预置试验次数，到设定值会自动停机，并伴有声音报警信号。
本机与旋转拉力测试仪CL-2的主要区别是双工位，主要为满足UL486标准设计，高度调节可达500mm，相应配套旋转砝码（最大22.7kg）及拉力砝码（最大578N）,可根据实际情况定制选用。

a If a hole with the diameter given is insufficient to accommodate the conductor without binding, a bushing having a hole of slightly large diameter shall be allowed to be used. |
b For 12 - 4 AWG (3.3 - 21.2 mm2) aluminum conductor, use 318 mm (12-1/2 in). |
