測試線又稱測試導線是電力系統檢修試驗時專用的測試線，適用于繼電保護現場，試驗室及其它試驗調試的場所，具有連接方便，只需進行插撥連接，不需開啟設備，接觸電阻小，導線柔軟，絕緣性能好等特點，專用測試導線與專用保護試驗裝置配套使用將大大提高現場調試效率，此外測試線也適用于儀器儀表配套、電氣測量及高壓專業的測試、試驗。測試導線(xian)(xian)(xian)(xian),電力測試線(xian)(xian)(xian)(xian)包,短(duan)接線(xian)(xian)(xian)(xian),三(san)聯四聯短(duan)接線(xian)(xian)(xian)(xian),雙(shuang)芯線(xian)(xian)(xian)(xian),三(san)芯線(xian)(xian)(xian)(xian),四芯線(xian)(xian)(xian)(xian),丁晴線(xian)(xian)(xian)(xian),多股軟(ruan)銅線(xian)(xian)(xian)(xian)

現有的電力測試(shi)(shi)線(xian)(xian)接線(xian)(xian)端(duan)(duan)口(kou)及測試(shi)(shi)線(xian)(xian)的連接結構(gou)在(zai)安裝了后不能對端(duan)(duan)口(kou)內部(bu)進行檢查和維修，而且(qie)測試(shi)(shi)線(xian)(xian)的連接結構(gou)不能對測試(shi)(shi)線(xian)(xian)進行保護(hu)，使(shi)得測試(shi)(shi)線(xian)(xian)連接處(chu)容易受到破壞，而使(shi)得測試(shi)(shi)線(xian)(xian)連接處(chu)斷(duan)裂(lie)，從而使(shi)得連接結構(gou)失去作用。
