PC電線管和PVC電線管的區(qū)別：1、材質(zhì)不同：PVC管的主要成份為聚百氯乙烯；PC管的主要成分為聚碳酸酯。2、兩種線管用途不同：度PVC管好煨彎，一般使用小口徑管路，用于室外監(jiān)控、報(bào)警等線路的保知護(hù)；PC管不好煨彎，一般用于強(qiáng)弱電管路的預(yù)埋。3、理化性質(zhì)道不同：PVC管的熱穩(wěn)定性和抗沖擊性較差，無論是硬性還是軟質(zhì)PVC使用過程中容易產(chǎn)生脆性；PC管具有突出的抗沖擊能力，耐蠕變和尺回寸穩(wěn)定性好，耐熱。PVC樹脂塑料制品突出優(yōu)點(diǎn)是難燃性、耐磨性、抗化學(xué)腐蝕性、氣體水汽低滲漏性好。此外綜合機(jī)械性能、制品透明性、電絕緣性，四川塑膠pvc電線套管價(jià)格、隔熱、消聲、消震性也好，是性能價(jià)格比**為優(yōu)越的通用型材料屬，四川塑膠pvc電線套管價(jià)格，四川塑膠pvc電線套管價(jià)格。缺點(diǎn)是熱穩(wěn)定性和抗沖擊性較差，無論是硬性還是軟質(zhì)PVC使用過程中容易產(chǎn)生脆性。單一電線護(hù)套管的絕緣結(jié)構(gòu)分為有空氣腔和空氣腔短路兩類。四川塑膠pvc電線套管價(jià)格</p><div

PVC電線套管選擇？PVC線槽的品種規(guī)格很多，知從型號(hào)上講有：PVC-20系列、PVC-25系列、PVC-25F系列、PVC-30系列、PVC-40系列、PVC-40Q系列等。每一種型號(hào)的PVC線槽都有各自的特色和缺點(diǎn)。如果真的要比道較好壞就只能從性價(jià)比比較了。pvc－u絕緣阻燃電工套管GY。G=管材；Y=硬質(zhì)套管，內(nèi)其他還有B指半硬質(zhì)，W指波紋容管；3=機(jī)械性能，這里3指中型，其他還有2輕型，4重型，5超重型；15=溫度等級(jí)，一般指管材的低溫或高溫性能，其他還有-5型，-25型等等；25=公稱外徑，常見的有16，20，25，32，40，63。四川聯(lián)塑pvc電線套管質(zhì)量單一電線護(hù)套管用非磁性材料以減少發(fā)熱。</p><div

PVC電線管常用的有4分和6分管。4分管也就是直徑16毫米線管，6分管也就是直徑20毫米線管，壁厚要視質(zhì)量zhidao而定，好的厚差的薄，一般大約為。兩種型號(hào)在鋪設(shè)線管時(shí)都要用到的，穿過線管的電線少就用16毫米線管的，穿過線管的電線多就用20毫米線管的，具體16分和20分管內(nèi)穿幾根線，也有標(biāo)準(zhǔn)的。一般管內(nèi)的電線的總截面積不應(yīng)超過管內(nèi)徑截面積的40%，只要電線穿進(jìn)版線管內(nèi)不要很緊，要留一定的空間，因?yàn)橐o電線發(fā)熱留下一點(diǎn)空間，保證電線的使用。pvc穿線管安裝注意事項(xiàng)1、當(dāng)然**重要的是要使用穿線管埋線。2、電路走線應(yīng)該把握“兩端間**近距離走線”，不能無故繞線，這樣不但會(huì)造成死線，還會(huì)增大電改投入。3、一根穿線管中不要穿太多線，穿線后都應(yīng)該拽一下，看看是否可以輕松拽動(dòng)。4、線路有接頭必需在接頭處留暗盒扣面板，日后更換和維修都方便。5、管徑小于25的PVC穿線管拐彎應(yīng)用彎管器，不能加彎頭拐彎。 </p><p> 電線是必須套進(jìn)電線套管內(nèi)的，否則電線外層的塑料絕緣皮長時(shí)間使用后，塑料皮會(huì)老化開裂，絕緣水平很大下降，很容易引起大面積漏電，危及人身安全。此外，漏泄的電流在流入地面途中，如遇電阻較大的部位，會(huì)產(chǎn)生局部高溫，致使附近的可燃物著火，引發(fā)火災(zāi)。所以，從安全角度考慮，也必須將電線套入線管中。電線護(hù)套管主要有兩種，一種是PVC塑料電線套管，還有一種是鋼管的。不管選用哪種電線套管，都能起到非常好的電線保護(hù)作用，這也是經(jīng)過很多年驗(yàn)證的，不需要擔(dān)心。熱膨脹系數(shù)小，不收縮變形。傳統(tǒng)的安裝連接方式。</p><div

電線護(hù)套管，是一種絕緣保護(hù)套管，用于電線電纜外部的保護(hù)。根據(jù)材質(zhì)性能可分四類：單一電線護(hù)套管、復(fù)合電線護(hù)套管、電容式電線護(hù)套管和不銹鋼護(hù)套管。電線護(hù)套管，其實(shí)也叫絕緣套管，是一種復(fù)合了絕緣材料的新型的復(fù)合材料管,它以樹脂為基體和其他增強(qiáng)材料復(fù)合而成的絕緣套管，用于穿用電線和保護(hù)電線，故稱為電線護(hù)套管。它具有抗壓力強(qiáng)、重量輕、內(nèi)壁光滑，摩擦系數(shù)小等特點(diǎn)，在穿用電線時(shí)輕松，不損傷電線。搬、運(yùn)要比金屬鋼管和水泥管輕松、方便。施工安裝簡便，既省事又省力。耐腐蝕性能強(qiáng)、絕緣、非磁性、耐酸、耐堿、阻燃型、抗靜電。它以樹脂為基體和其他增強(qiáng)材料復(fù)合而成的絕緣套管，用于穿用電線和保護(hù)電線，故稱為電線護(hù)套管。四川聯(lián)塑pvc電線套管質(zhì)量</p><p
