對于一般的家庭而言,4平方的電線就足夠使用了,當(dāng)然,在有特殊需要的時候,可以購買6平方電線。對于那種過大型電器,像是空調(diào),可以獨(dú)立電線出來供其使用。為了確保用電安全,就需要在電線上安裝一個防漏電的開關(guān),這樣就能做到雙重的安全保障。電線的平方數(shù)大致可分為2.5平方、4平方、6平方這三種。電線越粗,也就說明它的平方數(shù)越大。有的人認(rèn)為電線是越粗越好,但實(shí)際上卻不是這樣。我們應(yīng)該根據(jù)實(shí)際需要來選擇電線的平方數(shù)。
絕緣材料:高密度聚乙烯或聚丙烯,按照全色譜標(biāo)準(zhǔn)標(biāo)明絕緣線的顏色。絕緣線對:把二根不同顏色的絕緣線按不同的節(jié)距扭絞成對,并采用規(guī)定的色譜組合以便識別線對。纜芯結(jié)構(gòu):以25對為基本單位,超過25對的電纜按單位組合,每個單位用規(guī)定色譜的單位扎帶繞扎,以便識別不同的單位。

RS-485為半雙工,只有一對平衡差分信號線,不能同時發(fā)送和接收。使用RS-485通信接口和雙絞線可組成串行通信網(wǎng)絡(luò)(見),構(gòu)成分布式系統(tǒng),系統(tǒng)中Zui多可有32個站,新的接口件已允許連接128個站。RS-485接口多用雙絞線實(shí)現(xiàn)連接。個人計(jì)算機(jī)一般不配RS-485接口,但工業(yè)計(jì)算機(jī)配備RS-485接口較多。plc的不少通信模塊也配用RS-485接口。如西門子公司的S7系列CPU均配置了RS-485接口。
100對及以上線對的電纜加有1%的預(yù)備線對,但Zui多不超過6對。纜芯內(nèi)的間隙用石油膏填充。5、纜芯包帶:用聚脂薄膜帶繞包。6、屏蔽:銅絲屏蔽或用軋紋(或不軋紋)金屬帶,金屬帶縱包于通信電纜纜芯包帶之外。7、護(hù)套:藍(lán)色低密度聚乙烯。

鋼帶表面經(jīng)涂塑處理,以防腐蝕和水份侵入。23,22型采用雙層鋼帶繞包也有相似的性能。鎧裝通信電纜護(hù)套:黑色高分子量低密度聚乙烯或聚氯乙稀護(hù)套。護(hù)套厚度可取決于基本電纜外徑。識別和長度標(biāo)記:電纜外表有性識別標(biāo)記,標(biāo)記間間隔不大于1m,鎧裝通信電纜標(biāo)記內(nèi)容有:導(dǎo)線直徑、線對數(shù)量、電纜型號、長度、制造廠廠名代號及制造年份。
可靠接地時整個485線路的地線必須要有良好的接觸,從而保證電壓一致,因?yàn)樵趯?shí)際施工中,為了接線方便,將線剪成多段再連接,但是沒有將屏蔽線作良好的連接,從而使得其地線分成了多段,電壓不能保持一致,導(dǎo)致共模干擾。
