SGWH-T電(dian)纜(lan)(lan)外(wai)護套故障測(ce)試儀是查找鋪設后超高壓電(dian)纜(lan)(lan)外(wai)護層破損故障的專(zhuan)業設備。能在故障電(dian)纜(lan)(lan)停電(dian)情(qing)況(kuang)下，對電(dian)纜(lan)(lan)外(wai)護層故障進(jin)行(xing)準確定位。

CD9851高壓(ya)(ya)(ya)電橋電纜故障測(ce)試(shi)(shi)儀（高壓(ya)(ya)(ya)電橋法）各類礦用(yong)6KV以下(xia)電纜在(zai)煤礦地面進行(xing)擦傷(shang)，并在(zai)電纜修復后直流(liu)耐壓(ya)(ya)(ya)測(ce)試(shi)(shi)和泄漏(lou)電流(liu)試(shi)(shi)驗之用(yong)。是一臺符合《煤礦電氣試(shi)(shi)驗規程》要求的，實用(yong)性強的電纜修理(li)的電纜測(ce)試(shi)(shi)的綜合性*工具。

HDQ-30高壓(ya)電(dian)橋電(dian)纜(lan)故障測試(shi)儀基于MURRAY電(dian)橋原理而設計，內置高頻高壓(ya)電(dian)源電(dian)壓(ya)達(da)到30kv，適用(yong)于敷設后各種電(dian)線電(dian)纜(lan)的(de)擊(ji)穿(chuan)點（低阻(zu)(zu)、高阻(zu)(zu)及閃絡型擊(ji)穿(chuan)）及沒有擊(ji)穿(chuan)但(dan)絕緣電(dian)阻(zu)(zu)偏低點的(de)定位：如用(yong)兆歐表發現電(dian)纜(lan)阻(zu)(zu)值較低，但(dan)運行電(dian)壓(ya)下不(bu)擊(ji)穿(chuan)的(de)絕緣缺(que)陷(xian)點。當然，也可用(yong)于電(dian)纜(lan)廠內各種線纜(lan)的(de)缺(que)陷(xian)點定位。

PJK-15高壓(ya)(ya)(ya)數字電(dian)(dian)橋電(dian)(dian)纜故障測(ce)試儀是基于MURRAY電(dian)(dian)橋原(yuan)理而設(she)計的，采用(yong)開(kai)關電(dian)(dian)源構成(cheng)高壓(ya)(ya)(ya)恒(heng)流(liu)源，空載電(dian)(dian)壓(ya)(ya)(ya)15000V，短(duan)路(lu)電(dian)(dian)流(liu)5mA，可用(yong)于敷設(she)后各種電(dian)(dian)線電(dian)(dian)纜的擊穿(chuan)點及沒有擊穿(chuan)的缺陷點的定(ding)位。
