通信電纜-HYA是由多根互相絕緣的導線或導體絞成的纜芯和保護纜芯不受潮與機械損害的外層護套所構成的通信線路，在環境特別惡劣的地方，必要時在通信線纜護套的外面還可以安裝防護層。

通(tong)訊線纜-HYA高速資料(liao)傳(chuan)輸(shu)(shu)動(dong)(dong)態數(shu)據頻段(duan)較寬，通(tong)訊體積很高，受外物(wu)要(yao)素小，但(dan)難于(yu)后期的(de)(de)維修保養，可高速資料(liao)傳(chuan)輸(shu)(shu)動(dong)(dong)態數(shu)據打點話、電(dian)報(bao)、資料(liao)和(he)畫(hua)像等。是高速資料(liao)傳(chuan)輸(shu)(shu)動(dong)(dong)態數(shu)據打點話、電(dian)報(bao)、發傳(chuan)真(zhen)文件格式、智能(neng)電(dian)視機(ji)和(he)播報(bao)喜(xi)劇(ju)綜藝、資料(liao)和(he)另(ling)外聯(lian)通(tong)號(hao)的(de)(de)線纜。

這樣通過(guo)適用(yong)公共場(chang)合，通信技術(shu)電(dian)力電(dian)纜又(you)可劃分成方式三大類(lei)：

1. 遠(yuan)途線(xian)纜：傳送數據距離感長，通常實現(xian)重復(fu)使用，而言直觀埋(mai)在地(di)埋(mai)式，少量(liang)時候下所采(cai)用直埋(mai)安轉(zhuan)的習慣以及安轉(zhuan)在管(guan)網(wang)中。

2. 市(shi)區(qu)電(dian)力(li)數(shu)據(ju)(ju)(ju)線(xian)(xian)(xian)(xian)：電(dian)力(li)數(shu)據(ju)(ju)(ju)線(xian)(xian)(xian)(xian)內的接地(di)線(xian)(xian)(xian)(xian)“成雙(shuang)成對”，而是多(duo)數(shu)多(duo)，普遍安裝在(zai)水管中，一些的市(shi)區(qu)電(dian)力(li)數(shu)據(ju)(ju)(ju)線(xian)(xian)(xian)(xian)附掛在(zai)搭建物上(shang)或空(kong)架安裝。

3. 局用水纜：包(bao)括指在(zai)導電(dian)連接局內的使用的，普遍重新(xin)裝置在(zai)配(pei)線馬路上，都(dou)是(shi)的重新(xin)裝置在(zai)走地(di)線管中(zhong)；局用水纜使用在(zai)中(zhong)國鐵(tie)通(tong)局內輸送設配(pei)與(yu)互換設配(pei)中(zhong)間，、任何局內設配(pei)的內層，在(zai)中(zhong)國鐵(tie)通(tong)內層只(zhi)為消防安全，有(you)的時(shi)候候還必須(xu)要給局用水纜再加(jia)阻燃(ran)型保護套。
