船用電纜生產(chǎn)廠家對船用電纜導(dǎo)體單直徑一般的內(nèi)控要求
船用電纜的導(dǎo)體是采用鍍錫園銅線(簡稱鍍錫銅絲）絞制而成，執(zhí)行標(biāo)準(zhǔn)：GB/T4910-2009，通常其生產(chǎn)廠家對船用電纜導(dǎo)體的單絲直徑要求制定了內(nèi)控標(biāo)準(zhǔn)，但其內(nèi)控標(biāo)準(zhǔn)中導(dǎo)體的直徑偏差范圍必須符合國家標(biāo)準(zhǔn)規(guī)定，同時(shí)保證外觀光滑圓整；電性能及抗拉強(qiáng)度和斷裂伸長率應(yīng)符合標(biāo)準(zhǔn)規(guī)定，在生產(chǎn)過程中進(jìn)行控制，主要作如下規(guī)定：
|
型號規(guī)格
|
標(biāo)準(zhǔn)規(guī)定尺寸(mm)
|
企業(yè)規(guī)定值（mm）
|
企業(yè)內(nèi)控尺寸范圍(mm)
