船用電力電纜關鍵的技術指標點如下：

1、導線直流電阻的測量：

電線電纜的導電線芯主要傳輸電能或電信號。導線的電阻是其電氣性能的主要指標，在交流電壓作用時線芯電阻由于集膚效應、鄰近效應面比直流電壓作用時大，但在電眼頻率為50Hz時兩者相差(cha)很小，現(xian)在標(biao)準規定(ding)那(nei)個均只能要求檢測(ce)線(xian)芯的(de)(de)直流電阻或電阻率是否超過標(biao)準中(zhong)的(de)(de)規定(ding)的(de)(de)值，通(tong)過此項的(de)(de)檢查(cha)可以發現(xian)生產(chan)工(gong)藝中(zhong)的(de)(de)某些缺陷，如(ru)導線(xian)斷裂或其中(zhong)部分單線(xian)斷裂；導線(xian)截面(mian)不符(fu)合標(biao)準；產(chan)品的(de)(de)長度不正確等。

2、絕緣電阻的測試(shi)：

絕(jue)緣(yuan)電(dian)(dian)阻(zu)式反(fan)映電(dian)(dian)線電(dian)(dian)纜(lan)產品(pin)絕(jue)緣(yuan)特(te)性的重要(yao)指(zhi)標，與該產品(pin)的耐(nai)電(dian)(dian)強度，介質損耗，以及絕(jue)緣(yuan)材料在(zai)工作狀態下的逐(zhu)漸劣化等均有密切的關系。對于通(tong)信電(dian)(dian)纜(lan)，線間(jian)絕(jue)緣(yuan)電(dian)(dian)阻(zu)過低還會增大(da)回路(lu)衰減、回路(lu)間(jian)的串音及在(zai)導電(dian)(dian)線芯(xin)上(shang)進行遠距離供電(dian)(dian)泄露等，因此都要(yao)求絕(jue)緣(yuan)電(dian)(dian)阻(zu)應高于規(gui)定值。

3、絕緣(yuan)強(qiang)度(du)試驗（耐壓）：

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)絕(jue)緣(yuan)(yuan)強(qiang)(qiang)度(du)(du)是(shi)指(zhi)絕(jue)緣(yuan)(yuan)結構和絕(jue)緣(yuan)(yuan)材料承受電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作(zuo)用而不發生擊穿破(po)壞的(de)能力，為了檢查(cha)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜產(chan)品(pin)質量(liang)，保證產(chan)品(pin)能正常運行，所有(you)絕(jue)緣(yuan)(yuan)類(lei)型的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜一(yi)般都要(yao)進(jin)行絕(jue)緣(yuan)(yuan)強(qiang)(qiang)度(du)(du)試(shi)驗(yan)(yan)。絕(jue)緣(yuan)(yuan)強(qiang)(qiang)度(du)(du)試(shi)驗(yan)(yan)可(ke)(ke)分為耐壓試(shi)驗(yan)(yan)和擊穿試(shi)驗(yan)(yan)。 時間的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓一(yi)般高于該試(shi)品(pin)的(de)額定工(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，具體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓值和耐壓時間，產(chan)品(pin)標(biao)準中(zhong)均有(you)規定，通過耐壓試(shi)驗(yan)(yan)可(ke)(ke)以考驗(yan)(yan)產(chan)品(pin)在工(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓下運行的(de)可(ke)(ke)靠性(xing)和發現絕(jue)緣(yuan)(yuan)中(zhong)的(de)嚴(yan)重缺陷，也可(ke)(ke)發現生產(chan)工(gong)藝的(de)一(yi)些缺點(dian)。

4、老化及穩定性試驗：

老化試驗即是在應力（機械、電、熱）作用下，能否保持性能穩定的穩定性試驗。 熱老化試驗：簡單的熱老化試驗是考驗試品在熱的作用下發生老化的特性，把試品放在高于額定工作溫度溫度一定值的環境中，這樣在較高的溫度T下，得到(dao)較短的(de)壽命(ming)。

5、熱穩定試驗：

熱(re)穩定(ding)(ding)性試(shi)驗(yan)是(shi)電纜(lan)通過(guo)電流加(jia)熱(re)的(de)同時還(huan)承受一定(ding)(ding)的(de)電壓，在經歷一定(ding)(ding)周期(qi)加(jia)熱(re)之后，測(ce)定(ding)(ding)某(mou)些敏感(gan)的(de)性能(neng)參數(shu)來(lai)評定(ding)(ding)絕緣的(de)穩定(ding)(ding)性。 絕緣穩定(ding)(ding)性試(shi)驗(yan)分為(wei)長期(qi)的(de)穩定(ding)(ding)性試(shi)驗(yan)或短期(qi)的(de)加(jia)速老(lao)化試(shi)驗(yan)兩(liang)種(zhong)。
