隨著我國科學(xué)技術(shù)的不斷發(fā)展,通信電纜在我們的生活中已經(jīng)密不可分。通信電纜由多根絕緣導(dǎo)線或?qū)w組成。通信電纜也可以放在空中,也可以只買在管道和水下,也有很多種敷設(shè)方式。
通信電纜是傳輸頻段的一種,廣通信的容量大,不會受到外界干擾,但是不好修。它可以傳送電話、電報、數(shù)據(jù)和圖像。因此,通信電纜給生活帶來了巨大的成果。
我們在電腦上玩手機(jī)或者看電視,都離不開通訊的信號。通信電纜的機(jī)械特性適合于純銅導(dǎo)體的強(qiáng)度,其伸長率大于銅鋁包鋁導(dǎo)體,這意味著其酮體具有優(yōu)異的機(jī)械性能。從通信電纜的設(shè)計角度來看。
Communication cables are suitable for urban and township telecommunication lines of local telecommunication networks, and also for special network lines connected to public networks. Mainly used for pipeline laying. The inner and outer surfaces of the cable core and the shielding layer are filled and poured with petroleum paste to prevent moisture from invading. Under the environmental conditions of 30~C and 60~C, the mechanical and electrical properties of the cable remain unchanged.
Structure of communication cable:
Conductor: annealed bare copper wire with a diameter of 0.32, 0.40, 0.50, 0.60, 0.70, 0.80 and 0.90 mm.
Insulation material: high-density polyethylene, medium-density polyethylene or polypropylene, and the color of the insulated wire conforms to the full chromatographic standard.
Insulated wire pair: two insulated wires with different colors are twisted in pairs according to different pitches, and the specified chromatographic combination is adopted.
纜芯結(jié)構(gòu):以25對為基本單位,25對以上的電纜按單元組合,每單元用規(guī)定色譜的扎帶包裹,便于識別。100對或以上的電纜有1%的備用線對,但不超過6對。
纜芯膠帶:纜芯用聚酯薄膜膠帶包裹。
屏蔽:用0.2mm厚雙面涂塑鋁帶縱向包在纜芯帶外,然后在搭接處粘接。
護(hù)套:黑色低密度聚乙烯。可以提供雙護(hù)套電纜。
本公司堅持“以質(zhì)量求生存,以信譽(yù)求發(fā)展”的經(jīng)營理念和“客戶第一,誠信至上”的原則,熱忱歡迎各界朋友前來參觀、考察、洽談業(yè)務(wù)。
