船舶電力系統中各電纜的選擇步驟和原則
1、根據電纜的用途、敷設位置和工作條件選擇合適的電纜型號。
2、 根據用電設備的工作制、電源種類、電纜線芯和負載電流選擇合適的電纜截面。
3、根據系統短路電流計算結果，片斷電纜的短路容量是否滿足要求。
4、 根據環境溫度對電纜的額定載流量進行修正，然后再判斷電纜的允許電流是否大于負載電流。
5、 根據成束敷設修正系數，對電纜的額定載流量進行修正，然后，再判斷電纜的允許電流是否大于負載電流。
6、校核線路電壓降，判斷線路電壓降是否小于規定值。
7、根據保護裝置的整定值，判斷電纜與保護裝置是否協調；如果不協調，判斷是否可以改變合適的保護裝置或整定值，否則應重新選擇合適的電纜載面。
船用電纜型號的選擇應考慮下述因素：
1、電纜的用途———用于動力、照明和信號傳輸等。
2、電纜敷設位置———是否長期浸水、低溫和是否要求屏蔽等。
3、工作條(tiao)件———固定(ding)敷設(she)(she)、穿管數(shu)設(she)(she)和(he)可(ke)移動等。

船用電力電纜是船用電纜的一種，用于河海各種船舶及海上石油平臺等水上建筑的電力、照明和一般控制之用的船用電纜。船用電力電纜在船舶電力系統中，具有舉足輕重的作用，是整個船舶的命脈所在，它擔負著為船上各類電氣設備傳輸和分配電能的功能。
船用電纜型號的選擇應考慮下述因素：
1、電纜的用途———用于動力、照明和信號傳輸等。
2、電纜敷設位置———是否長期浸水、低溫和是否要求屏蔽等。
3、工作條件———固定敷(fu)設(she)、穿管(guan)數設(she)和可(ke)移動等(deng)。

船用電力電纜主要參數有型號規格、芯數、燃燒特性、額定電壓、溫度、標稱截面積等主要參數。其執行標準為：IEC60092-350，IEC60092-353或GB9331-88。
船用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)用(yong)于在船舶(bo)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)中連接(jie)各種(zhong)(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)設(she)備，以(yi)傳輸電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)或電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)信號。隨著船舶(bo)電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)化(hua)和(he)自(zi)動(dong)化(hua)程度的(de)不(bu)斷提(ti)高，船用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)的(de)品種(zhong)(zhong)和(he)用(yong)量(liang)(liang)不(bu)斷增(zeng)多。船用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)基本(ben)上(shang)分為電(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)、通信電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)及特種(zhong)(zhong)高頻電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)三大類，其中電(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)用(yong)于電(dian)(dian)(dian)(dian)(dian)(dian)力(li)、照明等(deng)(deng)系統，是船上(shang)使用(yong)多的(de)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)。對于電(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)來說,載流量(liang)(liang)是一個重要(yao)的(de)技術指標。載流量(liang)(liang)的(de)大小一般取決于電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)絕緣材料的(de)耐溫(wen)等(deng)(deng)級(ji)。在同徉的(de)敷設(she)條件下，耐溫(wen)等(deng)(deng)級(ji)越(yue)高.載流量(liang)(liang)就越(yue)大。如果環(huan)境溫(wen)度較高，而選擇的(de)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)絕緣耐溫(wen)等(deng)(deng)級(ji)又較低，以(yi)致由電(dian)(dian)(dian)(dian)(dian)(dian)流發熱(re)引起的(de)允許(xu)溫(wen)升很低，這是不(bu)經濟(ji)的(de)。船用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)的(de)護套(tao)(tao)應具有耐潮、耐油、耐燃燒及耐熱(re)老化(hua)等(deng)(deng)性(xing)能(neng)。常用(yong)的(de)護套(tao)(tao)材料有氯丁橡膠、氯磺(huang)化(hua)聚乙烯和(he)聚氯乙烯，此外尚有鉛護套(tao)(tao)。
