進(jìn)入公司商鋪 EV-SS充電樁電纜Submarine cable (submarine cable) is a wire wrapped with insulating material, laid on the seabed and river water for ecommunications transmission. Modern submarine cables use optical fiber as a material to transmit ephone and Internet signals. The world's first submarine cable was laid between England and France in 1850. China's first submarine cable was completed in 1888, a total of two, one is between Fuzhou and Taiwan, Shanghai, Shanghai and Shanghai (fresh water), a long sea of another one by the Tainan Anping to Penghu, up to 53 nautical miles in length ().
海底電纜分海底通信電纜和海底電力電纜。海底通信電纜主要用于通訊業(yè)務(wù),費(fèi)用昂貴,但保密程度高。海底電力電纜主要用于水下傳輸大功率電能,與地下電力電纜的作用等同,只不過(guò)應(yīng)用的場(chǎng)合和敷設(shè)的方式不同。由于海底電纜工程被世界各國(guó)*為復(fù)雜困難的大型工程,從環(huán)境探測(cè)、海洋物理調(diào)查,以及電纜的設(shè)計(jì)、制造和安裝,都應(yīng)用復(fù)雜技術(shù),因而海底電纜的制造廠家在世界上為數(shù)不多,主要有挪威、丹麥、日本、加拿大、美、英、法、意等國(guó),這些國(guó)家除制造外還提供敷設(shè)技術(shù)。目前我國(guó)應(yīng)用的海底電力電纜仍然需要進(jìn)口。
Submarine cable submarine communication cable and submarine power cable. The submarine communication cable is mainly used for communication business, the cost is high, but the degree of confidentiality is high. The submarine power cable is mainly used for the transmission of high power electric power under the water, which is equivalent to the underground power cable. The submarine cable project is recognized as the world of large complex engineering difficulties, from environmental exploration, marine geophysical survey, and cable design, manufacture and installation, the application of complex technology, so the manufacturer of submarine cables in the world are few, mainly in Norway, Denmark, Japan, Canada, the United States and Britain and France, Italy and other countries, these countries in manufacturing but also provide installation technology. At present, China's submarine power cables still need to import.
海底電纜分類(lèi)
Classification of submarine cables
浸漬紙包電纜：適用于不大于45kV交流電及不大于400kV直流電的線路。目前只限安裝于水深500m以?xún)?nèi)的水域。
Impregnated paper cable: not less than 45kV AC and not more than 400kV DC line. Currently only installed in the water depth of less than 500m.
自容式充油電纜：適用于高達(dá)750kV的直流電或交流電線路。由于電纜為充油式，故可以毫無(wú)困難地敷設(shè)于水深達(dá)500m的海域。
Self contained oil filled cable: suitable for DC or AC lines up to 750kV. As the cable for oil filled, it can be difficult to apply to the water depth of 500m of the sea.
擠壓式絕緣（交聯(lián)聚乙烯絕緣、乙丙橡膠絕緣）電纜：適用于高達(dá)200kV交流電壓。乙丙橡膠較聚乙烯更能防止樹(shù)枝現(xiàn)象及局部泄電，使海底電纜更有效地發(fā)揮功能。
Extruded insulation (XLPE insulated, ethylene propylene rubber insulated) cable: suitable for up to 200kV AC voltage. Ethylene propylene rubber is better than polyethylene to prevent the phenomenon of branches and local discharge, so that the submarine cable to play a more effective function.
“油壓”管電纜：只適用于數(shù)公里長(zhǎng)的電纜系統(tǒng)，因?yàn)橐褬O長(zhǎng)的電纜拉進(jìn)管道內(nèi)，受到很大的機(jī)械性限制。
"Oil" pipe cable: only for a few kilometers long cable system, because the cable into the very long cable into the pipeline, subject to a lot of mechanical limitations.
充氣式（壓力輔助）電纜：使用浸漬紙包的充氣式電纜比充油式電纜更適合于較長(zhǎng)的海底電纜網(wǎng)，但由于須在深水下使用高氣壓操作，故此增加了設(shè)計(jì)電纜及其配件的困難，一般限于水深為300m以?xún)?nèi)。
Inflatable (pressure assisted cable): the use of submarine cable network packet inflatable impregnated paper cable than oil filled cable is more suitable for long, but must use high pressure operation in deep water, therefore increases the design difficulty of cables and accessories, generally limited to the depth of less than 300m.EV-SS充電樁電纜
海底電纜用途
Submarine cable
海底通信電纜主要用于長(zhǎng)距離通訊網(wǎng)、通常用于遠(yuǎn)距離島嶼之間、跨*事設(shè)施等較重要的場(chǎng)合。海底電力電纜敷設(shè)距離較通信電纜相比要短得多,主要用于陸島之間、橫越江河或港灣、從陸上連接鉆井平臺(tái)或鉆井平臺(tái)間的互相連接等。在一般情況下,應(yīng)用海底電纜傳輸電能無(wú)疑要比同樣長(zhǎng)度的架空電纜昂貴,但用它往往比用小而孤立的發(fā)電站作地區(qū)性發(fā)電更經(jīng)濟(jì),在近海地區(qū)應(yīng)用好處更多。在島嶼和河流較多的國(guó)家,此種電纜應(yīng)用較廣泛。
Submarine communication cable is mainly used for long-distance communication network, usually used for remote islands, cross sea military facilities and other important occasions. The laying distance of submarine power cable is much shorter than that of communication cable, which is mainly used for the connection between land island, crossing rivers or bays, and connecting with the drilling platform or drilling platform on land. In general, the transmission of electrical cable can be used is more expensive than the overhead cable of the same length, but it more often than in small isolated power station for regional power in the offshore area of application is more economical, more benefits. In countries with more islands and rivers, such cables are widely used.
