三、使用范圍不同1、電線套管：?jiǎn)我浑娋€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。空氣腔套管用于10千伏及以下電壓等級(jí)，導(dǎo)體與瓷套之間有空氣腔作為輔助絕緣，可以減少套管電容，提高套管的電暈電壓和滑閃電壓。2、電工套管：用于室內(nèi)正常環(huán)境和在高溫、多塵、有震動(dòng)及有火災(zāi)危險(xiǎn)的場(chǎng)所。也可在潮濕的場(chǎng)所使用。不得在特別潮濕，四川川路塑膠pvc電線套管廠家直銷，有酸、堿、鹽腐蝕和有危險(xiǎn)的場(chǎng)所使用。電工套管：聚氯乙烯加入阻燃材料做成的一種白色不透明的穿線管，一、執(zhí)行標(biāo)準(zhǔn)：JG/T3050-1998二、產(chǎn)品規(guī)格:分為輕型-205、中型-305、重型-405三種。1，四川川路塑膠pvc電線套管廠家直銷、輕型-205外徑￠16mm-￠50mm2、中型-305外徑￠16mm-￠50mm3，四川川路塑膠pvc電線套管廠家直銷、重型-305外徑￠16mm-￠50mm（定長(zhǎng)一般為4m，特殊規(guī)格可按客戶定做）；單一電線護(hù)套管用非磁性材料以減少發(fā)熱。四川川路塑膠pvc電線套管廠家直銷</p><div

PVC穿線管主要成份為聚氯乙烯，加入其他成分來(lái)增強(qiáng)其耐熱性、韌性、延展性的一種材料。PVC可分為軟PVC和硬PVC。其中硬PVC大約占市場(chǎng)的2/3，軟PVC占1/3。軟PVC一般用于地板、天花板以及皮革的表層，但由于軟PVC中含有增塑劑（這也是軟PVC與硬PVC的區(qū)別），物理性能較差（如上水管需要承受一定水壓，軟質(zhì)PVC就不適合使用），所以其使用范圍受到了局限。硬PVC不含增塑劑，因此易成型，物理性能佳，因此具有很大的開(kāi)發(fā)應(yīng)用價(jià)值。聚氯乙烯材料生產(chǎn)過(guò)程中，勢(shì)必添加幾種助劑，如穩(wěn)定劑，增塑劑等等，倘若全部采用環(huán)保助劑。四川塑膠pvc電線套管一級(jí)經(jīng)銷商結(jié)構(gòu)和維修簡(jiǎn)單,可不用下套管，還可將心子下端車削成短尾式，縮小其尺寸。</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：?jiǎn)我浑娋€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(shù)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(jiǎn)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。 </p><p> PVC電線管的套管接頭一定要使用膠粘劑么？一定要使用膠粘劑。正規(guī)的做法應(yīng)該是：先把所有的沒(méi)有穿電線的保護(hù)管都埋入墻內(nèi)，天花板內(nèi)，然后，把線槽用水泥封掉，等到裝修好后，然后才從接線暗盒中穿電線。把電線穿好后再埋保護(hù)管，電線就變成一次性的了。以后想換新電線的話，根本抽不出來(lái)，不能換新電線。只能報(bào)廢。為了保護(hù)電纜，電纜敷設(shè)時(shí)在易受外力損傷的部位要加裝保護(hù)管。通常使用的保護(hù)管有鋼管和硬質(zhì)塑料管。保護(hù)管的內(nèi)徑不應(yīng)小于電纜外徑的。管壁厚度不小于2mm。硬質(zhì)塑料管不能用在溫度過(guò)高和過(guò)低的場(chǎng)所。通過(guò)基礎(chǔ)（包括地面或樓板）的保護(hù)管，內(nèi)徑在32mm及以下時(shí)，用鋼管保護(hù)。它以樹(shù)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。</p><div

PVC可分為軟PVC和硬PVC。其中硬PVC大約占市場(chǎng)的2/3，軟PVC占1/3。軟PVC一般用于地板、天花板以及皮革的表層，但由于軟PVC中含有增塑劑（這也是軟PVC與硬PVC的區(qū)別），物理性能較差（如上水管需要承受一定水壓，軟質(zhì)PVC就不適合使用），所以其使用范圍受到了局限。硬PVC不含增塑劑，因此易成型，物理性能佳，因此具有很大的開(kāi)發(fā)應(yīng)用價(jià)值。聚氯乙烯材料生產(chǎn)過(guò)程中，勢(shì)必添加幾種助劑，如穩(wěn)定劑，增塑劑等等，倘若全部采用環(huán)保助劑；具有優(yōu)良的力學(xué)性能。具有抗彎曲疲勞性。熱性能：具有良好的耐熱性，能在100℃以上溫度進(jìn)行消毒滅菌，在不受外力的條件下，150℃也不變形。脆化溫度為-35℃，在低于-35℃會(huì)發(fā)生脆化?；瘜W(xué)穩(wěn)定性：化學(xué)穩(wěn)定性很好，除能被濃、濃硝酸侵蝕外，對(duì)其它各種化學(xué)試劑都比較穩(wěn)定，防腐蝕效果良好。電性能：高頻絕緣性能優(yōu)良，由于它幾乎不吸水，故絕緣性能不受濕度的影響。空氣腔套管用于10千伏及以下電壓等級(jí)，導(dǎo)體與瓷套之間有空氣腔作為輔助絕緣；四川塑膠pvc電線套管一級(jí)經(jīng)銷商</p><p
