本機試法是取試件約5m長,中段撓于規(guī)定直徑之兩個圓輪上,兩端施加荷重,并接通電流,然后以0.33m/sec之速度,1m之行程,移動圓輪,使試件往復彎曲拉伸,當斷線或到達設定次數(shù),會自動停機,取下試件評定其耐撓曲性質。 Cutoffthecableabout5minlengthasbeingthetestspecimenwhichshallbekinkedoverthespecifieddiameterofbothwheelseachendhastobeloadedwithaweight。eanwhileeachconductorofsampleshallbeloadedwithacurrent。Later,atanapproximatelyconstantspeedof0.33m/stomovethewheelsoveradistanceof1mtomakethespecimenbereciprocallybenttightened。Whenthespecimenbreaksdownthepresetnumbersarereached,themachinewillstopautomatically。Afterwards,takeoffthesampleadjudgethecharacteristicofflexibility。 荷重 Load 1kg、1.5kg 滑輪直徑 Wheeldiameter 60mm、80mm、120mm(另有其它規(guī)格) 試驗電流 Testingcurrent 3~32A連續(xù)可調Adjustable 試驗電壓 Testingvoltage 0~380VAC連續(xù)可調Adjustable 計數(shù)器 Counter 電子式,6位數(shù),到達設定次數(shù), 自動停機Electronictype6digits, auto-stopduringthepresetnumbers 電源 Power AC220V/50Hz
