14px;">熱縮電纜頭采用熱源（一般采用石油液化氣噴槍，丙烷、0號(hào)無(wú)鉛汽油噴燈）加熱的方法使熱縮材料收縮安裝，收縮加熱溫度一般為110-140℃。加熱時(shí)由于技術(shù)要求比較嚴(yán)格，不能有欠烤、過(guò)烤、加熱不均等現(xiàn)象。</span></p> <p style="margin: 5px 0px; color: rgb(0, 0, 0);

font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">冷縮電纜頭安裝時(shí)，只需將線芯抽去，彈性橡膠體便迅速收縮并緊箍于所需安裝部位。所以冷縮材料不需要類似加熱裝置等專門的施工工具，安裝簡(jiǎn)單。</span></p> <p style="margin: 5px 0px; color: rgb(0, 0, 0); font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">二、高壓防爆<strong><a href="http://www.uf7o.cn/"><span style="color:#ff0000;">電纜連接器</span></a></strong>中間接頭工藝性價(jià)比</span></p> <p style="margin: 5px 0px; color: rgb(0, 0, 0); font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">（一）使用性能比較</span></p> <p style="margin: 5px 0px; color: rgb(0, 0, 0); font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">1. 高壓電纜連接器（高壓接線盒）過(guò)于笨重，運(yùn)輸安裝不方便，同時(shí)防潮性能不佳。</span></p> <p style="margin: 5px 0px; color: rgb(0, 0, 0); font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">2. 冷補(bǔ)施工</span></p> <p style="margin: 5px 0px; color: rgb(0, 0, 0); font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">（1）冷補(bǔ)作業(yè)時(shí)，三相芯線之間的距離及芯線距模具壁的距離不易把握，易出現(xiàn)灌膠后出現(xiàn)薄厚不均的情況，薄的地方容易出現(xiàn)受潮、擊穿等問(wèn)題，同時(shí)影響絕緣性能。</span></p> <p style="margin: 5px 0px; color: rgb(0, 0, 0); font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">（2）冷補(bǔ)作業(yè)時(shí)，灌膠需要人為灌注，灌注過(guò)程中，內(nèi)部容易出現(xiàn)氣泡，影響接頭的絕緣性能。</span></p> <p style="margin: 5px 0px; color: rgb(0, 0, 0); font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">（3）冷補(bǔ)接頭防潮、防水性能較差，其接頭抗拉強(qiáng)度不及熱縮和冷縮接頭。如：羊場(chǎng)灣煤礦在原Y120202工作面曾經(jīng)大面積使用，使用過(guò)程中多次出現(xiàn)漏電故障，嚴(yán)重影響生產(chǎn)，最后全部更換為冷縮頭，未再出現(xiàn)接頭故障現(xiàn)象。</span></p> <p style="margin:

0, 0); font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">?（1）由于熱縮材料的穩(wěn)定性，所以存放時(shí)間相對(duì)比較長(zhǎng)。工程中，熱縮材料因其產(chǎn)品成熟、可靠及普及性，得以推廣和應(yīng)用，在現(xiàn)場(chǎng)長(zhǎng)期運(yùn)行中發(fā)現(xiàn)除去因制作工藝上出現(xiàn)的問(wèn)題外，熱縮電纜頭能夠保證電纜長(zhǎng)期安全穩(wěn)定運(yùn)行?，F(xiàn)羊場(chǎng)灣煤礦Y120203工作面安裝時(shí)，約15000米高壓電纜大部分采用了熱縮中間頭，現(xiàn)工作面即將開(kāi)采完，未出現(xiàn)一例不合格接頭。</span></p> <p style="margin: 5px 0px; color: rgb(0, 0, 0); font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">（2）熱縮受操作水平的影響比較大，加熱時(shí)候不均勻會(huì)導(dǎo)致熱縮材料收縮薄厚不均勻、燒焦絕緣管、收縮時(shí)產(chǎn)生氣泡等情況發(fā)生，影響了絕緣管的絕緣性能。</span></p> <p style="margin: 5px 0px; color: rgb(0, 0, 0); font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">（3）井下作業(yè)時(shí)，施工條件限制較大，需動(dòng)火施工。</span></p> <p style="margin: 5px 0px; color: rgb(0, 0, 0); font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">（4）施工人員需要經(jīng)過(guò)一定的專業(yè)技術(shù)培訓(xùn)才能進(jìn)行正確熟練操作。</span></p> <p style="margin: 5px 0px; color: rgb(0, 0, 0); font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">4.高壓防爆<strong><a href="http://www.uf7o.cn/"><span

style="font-size: 14px;">（1）根據(jù)冷縮材料廠家技術(shù)資料，35kV以下冷縮材料其有效安裝期一般為6個(gè)月內(nèi)，最長(zhǎng)有效安裝期限不得超過(guò)兩年，否則電纜附件的使用壽命將受到影響。工程中，冷縮材料因易于安裝的特點(diǎn)，也逐步得以推廣和應(yīng)用，目前羊場(chǎng)灣煤礦Y120204工作面安裝時(shí)，所有高壓電纜全部采用冷縮中間頭，從2010年10月份安裝至今，未出現(xiàn)一例故障接頭。</span></p> <p style="margin: 5px 0px; color: rgb(0, 0, 0); font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">（2）冷縮電纜附件減少過(guò)多的人為因素，在施工中，冷縮只要抽掉里面的塑料線芯就可以自動(dòng)收縮，在收縮過(guò)程中不會(huì)因?yàn)槿藶榈囊蛩貙?dǎo)致絕緣管收縮不均勻的現(xiàn)象，也不會(huì)出現(xiàn)氣泡，保證了施工的質(zhì)量。</span></p> <p style="margin: 5px 0px; color: rgb(0, 0, 0); font-family: sans-serif; font-size: 16px; line-height: 2em; text-indent: 2em;"> <span style="font-size: 14px;">（3）冷縮接頭防潮、防水性能較強(qiáng)，外護(hù)套加裝了一層鎧裝帶，堅(jiān)固性較強(qiáng)。</span></p> <p
