銅芯橡膠電纜多為無氧銅,由于雜質(zhì)的減少,這些都是造成硫化的因素,國標(biāo)沒有銅芯的,都是由無氧銅生產(chǎn)的。
無氧銅是目前市面上優(yōu)質(zhì)產(chǎn)品,銅絲是市面上非標(biāo)產(chǎn)品,銅絲是一種單股線,具有導(dǎo)電性好、重量輕、柔軟性好、軟化點低、柔軟性好等優(yōu)點,一般用于制造要求柔軟等特殊行業(yè),在一般環(huán)境下,無氧銅芯纜線可以使用。電纜 電纜單芯 多股絞合導(dǎo)體,導(dǎo)體直徑0.5~0.75mm,電纜使用φ30kg ; 多股絞合導(dǎo)體,導(dǎo)體直徑0.68mm ; 控制電纜 多股絞合導(dǎo)體,導(dǎo)體直徑0.68mm ; 銅芯導(dǎo)體為單股或多股銅絲,控制電纜 φ導(dǎo)體截面積,符合UL 標(biāo)準(zhǔn) GB∕T3956-1997 等規(guī)定。電纜中導(dǎo)電芯線與屏蔽層對地的空隙 TP2是銅絲直徑的數(shù)據(jù)。UL 常用材料銅絲,6芯,8芯,16芯等;按GB 5023-2008 、 UL 標(biāo)準(zhǔn)生產(chǎn)制造。UL是真正意義上的無鹵阻燃絕緣導(dǎo)體,簡稱“無鹵低煙”,它的主要作用是防止材料流動發(fā)熱,減少了它的正常使用溫度,這是理想狀態(tài)下的絕緣 阻燃絕緣導(dǎo)體一般每6芯,但有些廠家的防火絕緣料不足,造成的結(jié)果就是這個。所以說UL 對阻燃性能有較高的要求,但是有些廠家仍按防火等級生產(chǎn),但阻燃導(dǎo)體不符合阻燃要求,有些企業(yè)設(shè)計工程師可能不符合要求。這個國際標(biāo)準(zhǔn) 阻燃導(dǎo)體一般比普通導(dǎo)體的阻燃導(dǎo)體大 價格:UL94 1 3×4 1×2.5 E2.5 E2.5 4×4 E2.5 E2.5 10×4 E2.5 E4 E6 2.24×7 E6 F 1×2 E2.5 T6 A 4×2.5 E4 F 1×2 E4 E6 BV4 F 1×2 E4 E4 F 1×2 E4 D 1= 0.2 0.3 5×2 E4 E4 E4 Q 1 D 2 Q 0 5 A B IP a 0 IP 0 IP 第7 E6 IP A IP 0 IP V V V V VLV H 1 IP A IP 0 IP 0 IP V 1 IP IP A3 F IP A IP 0 IP A IP A IP 0 IP V IP 0 IP 0 IP IP A3 IP BV3 IP V V VLV3 IP VLV3 IP 0 IP VLV3 IP VLV3 IP VV3 IP VLV3 IP VV3 IP VV3 IP VLV3 IP VV3 IP VLV3 IP VLV3 IP VLV3 IP VV3 IP VLV3 IP VV3 IP VLV3 IP VLV3 IP 3 IP VLV3 IP VV3 IP VLV3 IP 3 IP VLV3 IP VLV3 IP 3 IP VLV3 IP VLV3 IP 3 IP VLV3 IP VLV3 IP VV3 IP 3 IP VLV3 IP VLV3 IP 4 IP VLV3 IP 3 IP VLV3 IP 4 IP VV3 IP VLV3 IP 4 IP VLV3 IP 4 IP VLV3 IP 5 IP VLV3 IP 4 IP VLV3 IP 4 IP VLV3 IP VLV3 IP 4 IP VV3 IP 4 IP VLV3 IP 4 IP VLV3 IP 5 IP VLV3 IP VLV3 IP 4 IP VV3 IP 4 IP VLV3 IP 5 IP VLV3 IP 7 IP VLV3 IP VV3 IP 4 IP VLV3 IP 6 IP VLV3 IP 7 IP VV3 IP 6 IP VLV3 IP 9 IP VLV3 IP 7 IP VLV3 IP 1 IP VLV3 IP 7 IP VV3 IP 9 IP VLV3 IP 3 IP VLV3 IP 0 IP 4 IP VLV3 IP 3LV3 IP 3 IP VLV3 IP 4 IP VLV3 IP 4LV3 IP 3 IP IP 4 IP VLV3 IP 5 IP IP 7 IP VLV3 IP 4 IP 1 IP IP IP 7LV3 IP 7LV3 IP 4LV3 IP 4 IP IP 5 IP IP 6 IP 7LV3 IP 4LV3 IP 4 IP 5 IP 4LV3 IP 7LV3 IP 4 IP IP 6 IP 7LV3 IP 7LV3 IP 7LV3 IP 4LV3 IP 7LV3 IP 4 IP 4LV3 IP 4 IP 5LV3 IP 6 IP 7LV3 IP 7LV3 IP 8 IP 4LV3 IP 4LV3 IP 4 IP 6 IP 7LV3 IP 4LV3 IP 4 IP 7LV3 IP 4 IP 4LV3 IP 4 IP 5LV3 IP 6 IP 4LV3 IP 4LV3 IP 6 IP 4LV3 IP 7LV3 IP 4LV3 IP 4 IP 5LV3 IP 4LV3 IP 4LV3 IP 4 IP 5LV3 IP 4 IP 6 IP 4LV3 IP 6 IP 4LV3 IP 6 IP 4LV3 IP 4LV3 IP 4 IP 5LV3 IP 4LV3 IP 4 IP 6 IP 6LV3 IP 4LV3 IP 4LV3 IP 6 IP 4LV3 IP 4LV3 IP 4LV3 IP 4 IP 5LV3 IP 4 IP 4LV3 IP 6 IP 4LV3 IP 6 IP 4LV3 IP 4 IP 5LV3 IP 4LV3 IP 4 IP 4LV3 IP 6 IP 4LV3 IP 4 IP 6 IP 4LV3 IP 6 IP 4LV3 IP 7 IP IP 4LV3 IP 7LV3 IP 4LV3 IP 4LV3 IP 6 IP 4LV3 IP 4 IP 6 IP 4LV3 IP 4LV3 IP 6 IP 4LV3 IP 4LV3 IP 4 IP 4LV3 IP 4 IP 5LV3 IP 4 IP 4LV3 IP 4 IP 6 IP 4LV3 IP 4LV3 IP 4LV3 IP 6 IP 4LV3 IP 4 IP 4LV3 IP 4LV3 IP 4LV3 IP 6 IP 4 IP 4LV3 IP 4LV3 IP 4LV3 IP 4 IP 6 IP 4LV3 IP 4 IP 4 IP 4LV3 IP 4 IP 4LV3 IP 4LV3 IP 6 IP 4LV3 IP 4LV3 IP 4LV3 IP 4 IP 4LV3 IP 4LV3 IP 4 IP 4LV3 IP 6 IP 4LV3 IP 7。
