1簡介

船用電(dian)(dian)(dian)纜(lan)又稱(cheng)船用電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)，是一種用于河(he)海(hai)各種船舶及海(hai)上石油平(ping)臺等水上建筑(zhu)的電(dian)(dian)(dian)力、照明(ming)和一般控制之用的電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)。

主要用(yong)途：應用(yong)于用(yong)于河(he)海各(ge)種船舶(bo)及海上石油(you)平(ping)臺等水(shui)上建筑的電力、照(zhao)明和一(yi)般控制之用(yong)。

執(zhi)行標(biao)準：船用(yong)電(dian)力(li)電(dian)纜的執(zhi)行標(biao)準：IEC60092-350，IEC60092-353或GB9331-88。

船用(yong)電力電纜主(zhu)要參數(shu)有型(xing)號規格(ge)、芯(xin)數(shu)、燃燒特性、額(e)定電壓、溫度、標稱截(jie)面(mian)積等主(zhu)要參數(shu)。

2分類

從種類上分，船(chuan)用電纜(lan)(lan)可分為(wei)兩(liang)類：民船(chuan)用電線電纜(lan)(lan)、軍艦用電線電纜(lan)(lan)。

從用(yong)(yong)途上(shang)分，船(chuan)用(yong)(yong)電(dian)纜(lan)可(ke)分為三類(lei)：船(chuan)/艦用(yong)(yong)電(dian)力電(dian)纜(lan)、船(chuan)/艦用(yong)(yong)控制電(dian)纜(lan)、船(chuan)/艦用(yong)(yong)通訊電(dian)纜(lan)。其作用(yong)(yong)分別(bie)是：

船(chuan)用(yong)(yong)電力(li)電纜：用(yong)(yong)于河海各種(zhong)船(chuan)舶(bo)及(ji)海上石(shi)油平臺等水上建筑的(de)電力(li)、照明(ming)和一般控(kong)制(zhi)之(zhi)用(yong)(yong)。

船用(yong)控制電纜：用(yong)于河海(hai)各種船舶及海(hai)上石油平臺(tai)等水上建筑一般控制之用(yong)。

船用通(tong)信電纜：用于各種傳播通(tong)信、電子計算機(ji)、信息處理設備中(zhong)的信號傳輸和控制系統。

3選擇原則

船舶電(dian)力(li)系(xi)統中(zhong)各電(dian)纜的選擇步驟和原(yuan)則

1、根據電纜的用途、敷設(she)位置(zhi)和工作條件選(xuan)擇合適的電纜型號。

2、 根據用電(dian)設備(bei)的工作制、電(dian)源種類、電(dian)纜(lan)線(xian)芯(xin)和(he)負載電(dian)流(liu)選(xuan)擇合(he)適的電(dian)纜(lan)截面。

3、根據系統短(duan)路電(dian)流計算結果，片斷(duan)電(dian)纜的短(duan)路容量是否滿足要求。

4、 根據環境溫度對電纜的(de)額定載流(liu)量進行修正，然后再判斷(duan)電纜的(de)允許電流(liu)是否大(da)于(yu)負載電流(liu)。

5、 根(gen)據成束敷設(she)修正(zheng)系數，對電(dian)纜的(de)額定(ding)載(zai)流量進(jin)行修正(zheng)，然(ran)后，再判(pan)斷電(dian)纜的(de)允許(xu)電(dian)流是否(fou)大(da)于(yu)負載(zai)電(dian)流。

6、校核線路電(dian)壓(ya)降(jiang)，判斷(duan)線路電(dian)壓(ya)降(jiang)是(shi)否小于規(gui)定值。

7、根據保護(hu)裝置的整(zheng)(zheng)定(ding)值，判(pan)(pan)斷電(dian)纜與(yu)保護(hu)裝置是否協調(diao)；如(ru)果不協調(diao)，判(pan)(pan)斷是否可以改(gai)變合(he)適(shi)的保護(hu)裝置或整(zheng)(zheng)定(ding)值，否則應重新選擇合(he)適(shi)的電(dian)纜載面。

船用電纜型號選擇

船用電纜(lan)型號的選擇應考慮下述因素：

1、電纜的用途(tu)———用于動力(li)、照明和無線電通信(xin)等。

2、電纜敷(fu)設位置(zhi)———干燥、潮濕、低溫和是否要(yao)求屏蔽(bi)等。

3、工作條件———固定敷設、穿管數設和(he)可移動等。

4發展趨勢

根據幾年國內(nei)外船舶工(gong)業的發展(zhan)，預計未來船舶市場需(xu)求呈現出以大噸位為主，具有高技(ji)術含量和高附加值等特點(dian)。
