電纜保護(hù)套管是電力工程中推廣使用的一種新型套管材料。隨著電力電纜埋地敷設(shè)工程的迅速發(fā)展，對電纜套管提出的更高要求，電纜保護(hù)套管是采用聚乙烯PE和質(zhì)量鋼管經(jīng)過噴砂拋丸前處理、浸塑或涂裝、加溫固化工藝制作而成。它是保護(hù)電線和電纜**常用的一種電絕緣管。因?yàn)榫哂薪^緣性能良好、化學(xué)穩(wěn)定性高、不生銹、不老化、可適應(yīng)苛刻環(huán)境而被大面積得以應(yīng)用。1、耐腐蝕，使用壽命長，可在潮濕鹽堿地帶使用。2、阻燃、耐熱性好，可在130度高溫下長期使用而不變形，遇火不燃燒。3、強(qiáng)度高、剛度高。用在行車道下直埋無需加混凝土保護(hù)層，能輥快電纜工程建設(shè)進(jìn)度。4、管材有柔性，能抵御外界重壓和基礎(chǔ)沉降所引起的破壞。5、具有良好的抗外界信號干擾性能。6、內(nèi)壁光滑，不刮傷電纜。設(shè)計采用承插式的連接方式，方便安裝連接。接頭處加橡膠密封圈封既適應(yīng)熱脹冷縮，又防止泥砂進(jìn)入。單一電線護(hù)套管用非磁性材料以減少發(fā)熱。</p><div

5、方便施工如果直接鋪設(shè)電線，不利于工人把握電路的走向，施工時，也很難保證電線橫平豎直的排列，更無法做到相應(yīng)的強(qiáng)弱電距離間隔等規(guī)范。二、電線管特點(diǎn)1、電線套管具有良好的耐腐蝕，使用壽命長，可在潮濕鹽堿地帶使用。2、阻燃、耐熱性好，可在130度高溫下長期使用而不變形，遇火不燃燒。3、強(qiáng)度高、剛度高。用在行車道下直埋無需加混凝土保護(hù)層，能輥快電纜工程建設(shè)進(jìn)度。4、電線套管無論是管材還是管件都具有一定柔性，能抵御外界重壓和基礎(chǔ)沉降所引起的破壞。5、具有良好的抗外界信號干擾性能。 PC管不好煨彎，一般用于強(qiáng)弱電管路的預(yù)埋。四川口碑好pvc電線套管供應(yīng)商</p><p style="text-indent:25px">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。四川口碑好pvc電線套管供應(yīng)商</p><p> 三、使用范圍不同1、電線套管：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。空氣腔套管用于10千伏及以下電壓等級，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、有震動及有火災(zāi)危險的場所。也可在潮濕的場所使用。不得在特別潮濕，有酸、堿、鹽腐蝕和有危險的場所使用。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、輕型-205外徑￠16mm-￠50mm2、中型-305外徑￠16mm-￠50mm3、重型-305外徑￠16mm-￠50mm（定長一般為4m，特殊規(guī)格可按客戶定做）；四川口碑好pvc電線套管供應(yīng)商</p></p><br
