船用電纜生產廠家對船用電纜導體單直徑一般的內控要求
船用電纜的導體是采用鍍錫園銅線(簡稱鍍錫銅絲）絞(jiao)制而成，執(zhi)行標(biao)準：GB/T4910-2009，通常其生(sheng)產廠(chang)家(jia)對船用電纜導(dao)體的(de)單絲直(zhi)徑要求制定(ding)了內控標(biao)準(zhun)(zhun)，但(dan)其內控標(biao)準(zhun)(zhun)中導(dao)體的(de)直(zhi)徑偏(pian)差(cha)范圍必須符(fu)合國家(jia)標(biao)準(zhun)(zhun)規定(ding)，同時(shi)保證外觀光滑(hua)圓整；電(dian)性(xing)能及抗拉強度和斷裂伸長率應(ying)符合標準規(gui)定，在生產過程中進(jin)行控制，主要作如(ru)下(xia)規定：
|
型(xing)號規(gui)格
|
標(biao)準規(gui)定尺(chi)寸(mm)
|
企業規定值(zhi)（mm）
|
企業內控尺寸范圍(wei)(mm)
