NH-YJV-0.6-1KV-3X35+

五芯電纜就是有(you)五個相互絕緣的(de)芯線，其(qi)外面又有(you)包(bao)裹這五個芯線的(de)塑料(liao)護(hu)套或鋼(gang)鎧加塑料(liao)護(hu)套。

包括(kuo)有(you)五個(ge)(ge)均設有(you)絕緣層(ceng)的(de)芯導(dao)體(ti)，于各個(ge)(ge)芯導(dao)體(ti)之外(wai)(wai)設有(you)一外(wai)(wai)護層(ceng)，其中一芯導(dao)體(ti)為(wei)(wei)截(jie)(jie)面呈圓形(xing)、圓形(xing)、扁形(xing)的(de)結構(gou)，另外(wai)(wai)四個(ge)(ge)芯導(dao)體(ti)為(wei)(wei)截(jie)(jie)面呈瓦楞形(xing)的(de)結構(gou)，該瓦楞形(xing)的(de)外(wai)(wai)邊(bian)為(wei)(wei)圓弧，內(nei)邊(bian)為(wei)(wei)直線，四個(ge)(ge)截(jie)(jie)面呈瓦楞形(xing)的(de)芯導(dao)體(ti)以內(nei)邊(bian)朝(chao)內(nei)的(de)方(fang)式而分布于所(suo)述截(jie)(jie)面呈圓形(xing)的(de)芯導(dao)體(ti)的(de)周邊(bian)，且各芯導(dao)體(ti)之間填設有(you)填充物。

三相五線制

三(san)(san)相五(wu)(wu)線(xian)(xian)制中(zhong)(zhong)五(wu)(wu)線(xian)(xian)指的是(shi)(shi)：三(san)(san)根(gen)相線(xian)(xian)加一根(gen)零線(xian)(xian)和(he)一根(gen)接地(di)線(xian)(xian)。一般(ban)用途較廣的低壓(ya)(ya)輸電(dian)(dian)方式是(shi)(shi)三(san)(san)相四線(xian)(xian)制，采用三(san)(san)根(gen)相線(xian)(xian)加零線(xian)(xian)供(gong)電(dian)(dian)，零線(xian)(xian)由變壓(ya)(ya)器中(zhong)(zhong)性點(dian)引出并接地(di)，電(dian)(dian)壓(ya)(ya)為380/220V，取任意(yi)一根(gen)相線(xian)(xian)加零線(xian)(xian)構成220V供(gong)電(dian)(dian)線(xian)(xian)路供(gong)一般(ban)家庭用,三(san)(san)根(gen)相線(xian)(xian)間(jian)電(dian)(dian)壓(ya)(ya)為380V，一般(ban)供(gong)動力使(shi)用。人們常常把(ba)TN-S系統(tong)說成三(san)(san)相五(wu)(wu)線(xian)(xian)制，其實(shi)是(shi)(shi)錯(cuo)誤(wu)的，按照(zhao)國家規范(fan)JGJ46-2005施工(gong)現(xian)場臨時用電(dian)(dian)安全(quan)技術(shu)規范(fan)中(zhong)(zhong)9.14條中(zhong)(zhong)說明，三(san)(san)相五(wu)(wu)線(xian)(xian)制是(shi)(shi)錯(cuo)誤(wu)的說法，只能說是(shi)(shi)五(wu)(wu)芯(xin)線(xian)(xian)纜。

三相四線制

三(san)相四線(xian)制：三(san)根相線(xian)加一根零線(xian)

區別

三(san)相(xiang)五(wu)線(xian)制比三(san)相(xiang)四線(xian)制多一根地線(xian)，用于安(an)全要(yao)求較高，設備要(yao)求統(tong)一接地的(de)場所。
