銅芯耐熱125℃交聯(lián)聚烯烴絕緣無鹵低煙阻燃機車
車輛用電纜(“CCC’’認證產(chǎn)品)
125℃ Low smoke non halogen flame retardant polytefin insulated wire for Locomotives(“CCC" authentication product)
前言:
我國目前已對機車車輛、地鐵、輕軌等城市交通運輸投入大量資金進行升級換代或改造.以緩解交通運輸和城市路面擁擠的狀況,如上海、廣州、深圳等地區(qū)建造地鐵,以及對北京、天津地鐵的更新改造等工程都需要大量的電線電纜與之配套,但目前我國尚沒有與其相匹配的電線電纜,為此我公司針對機車車輛、地鐵車輛等實際情況.以及國際上以該環(huán)境下使用的電線電纜特殊要求,我們研制開發(fā)出了125℃級輻照交聯(lián)低煙無鹵阻燃聚烯烴絕緣機車車輛專用電纜系列產(chǎn)品,該電纜額定電壓為3000V及以下。由于該電纜具有耐高低溫、外徑小、重量輕、低煙無鹵阻燃電氣性能和機械物理性能優(yōu)異等顯著特點,特別適用于升級換代、出口配套和要求高速重載的機車車輛、地鐵、輕軌等設備的動力傳輸和各種控制系統(tǒng)。又由于該電纜均是采用稱之為“潔凈”的低煙無鹵材料為絕緣的,其主要是在火災環(huán)境下燃燒產(chǎn)生很低的煙霧和微量的毒性氣體,從而為現(xiàn)場救援人員及內(nèi)部受災人員創(chuàng)造了一個良好的生存和救護環(huán)境,同時又由于產(chǎn)生的鹵素很少.因此又減少了因火災給精密儀器設備等造成的“二次災害”從而減少像土耳其纜車遂道中所發(fā)生的悲劇,特別是像機車車輛、地鐵等這樣密閉性更強的環(huán)境,采用該型電纜更為重要。同時由于該電纜是采用以高能電子射線對有機熱縮性材料進行輻照而使其由線性高分子轉(zhuǎn)變成三維立體網(wǎng)狀交聯(lián)結(jié)構(gòu).即以熱塑性轉(zhuǎn)化為不溶熔的熱固態(tài)物質(zhì),以使電線電纜的工作溫度由原來的70℃達到了125℃,短路抗過載溫度由原來的160℃達到了250℃.同時亦改善和提高了物理機械性能,又大大降低了電線電纜的成品外徑.輻照交聯(lián)方式可避免被化學交聯(lián)破壞低煙無鹵特性,對此我們開發(fā)研制了該產(chǎn)品。在提高各項性能的同時.也是機車車輛、地鐵車輛等密閉性強的場所使用的最佳選擇方案,為此我將在以下幾個方面重點介紹該產(chǎn)品。
At present, many large cities, Shanghai, Beijing, Guangzhou, Shenzhen, Tianjin, Shenyang, etc, they all plunge lot of financing into railway traffic, in order to change the status of traffic jam. The entire item needs large numbers of cables for locomotives, but we have no right cables in
The insulation material of the cable is radiation crosslink polytefin. It is a new flame retardant material protecting environment from destruction or pollution. When the burning happen, the radiation crosslink polytefin with smaller quantity of smoke and toxic gas, these properties can provide a good lifesaving environment, it can reduce the harm to extra equipment and instrument. Because the airtight environment, it is important to use this kind of cable in the railway traffic, so we can avoid the cothurnus like which happened in turkey cable car tube.
Because the radiation polytifen material is cross linkable, the radiation crosslink process makes a change to the material, to make the material structure from line to three-dimensional netlike structure. This process can also improve the high-cold retardant and anti-overloading properties. Especially, the radiation crosslink process doesn’t hurt the low smoke non halogen flame retardant properties.
Summarize all the properties; the low smoke non halogen flame retardant polytifen cable for locomotives is the best choice for the subway, railway and railcar locomotives.

10. 優(yōu)異的載流特性:
由于電纜絕緣層減。崃己,又由于絕緣材料耐熱性能顯著提高,因此使電纜載流水平和抗過載能力也大大提高。
Because the cable own thinner insulation thickness, and the polyfiten exhale the heat from the cable rapidly, these properties improve ability of electric current carrying capacity and anti-overloading.
