style="text-indent:25px">U型環(huán)強度計算：連接是一種松連接方式。在U型環(huán)與孔、雙板與單板之間總有一些間隙，因此U型環(huán)要承受彎矩(與U型環(huán)受剪切相比，彎矩居主要地位)故必須計算器抗彎強度。U型環(huán)的剪應力為:Tp-U型環(huán)的許用剪應力，N/mm2，U型環(huán)的常用材料鋼Q235、Q245，.可取Tp=80N/mm2;d-U型環(huán)的直徑，mm。P-作用在U型環(huán)上的外荷載，N。在外荷載P的作用下，并假定荷載通過孔板傳到U型環(huán)上，沿零件的寬度均勻分布，則U型環(huán)上所產(chǎn)生的彎矩為:M=2(24)兩支之間的距離，mm;l=1.05A經(jīng)熱鍍鋅后的鍛制件、沖壓件的外觀質量:沖裁件的剪切斷面斜度偏差小于板厚的十分之一。</p><p style="text-indent:25px">傳統(tǒng)的電力廠家使用的U型環(huán)主要由增強殼體、穿刺具片、防水硅脂、**度螺栓和螺母組成，其螺母推薦力矩螺母，其結.構較為成熟，也得到較為比較廣的的應用。但是傳統(tǒng)電力U型環(huán)也存在不足之處，夾線的壓力依靠普通螺栓組件的壓力，其牢固性較差，容易松動。在架空電力線路的施工中，當電纜需做分支或接續(xù)時，需要用電力U型環(huán)將兩根絕緣導線連接在一起。電力U型環(huán)具有安裝簡便，低成本，安全可靠免維護的特點。無需截斷主電纜、無需剝去電纜的絕緣層即可做電纜分支，接頭完全絕緣，可帶電作業(yè)，可以在電纜任意位置作現(xiàn)場分支;不需使用終端箱、分線箱;且接頭耐扭曲，防震、防水、防腐蝕老化，硅橡膠

style="text-indent:25px">U型環(huán)的檢驗一般分設計試驗、型式試驗、抽樣試驗和逐個試驗。為提高U型環(huán)的運行可靠性，有必要進行補充試驗。試驗要求和方法逐個和抽樣試驗U型環(huán)逐個試驗和抽樣試驗應滿足IEC61109的要求。耐受電壓試驗濕工頻耐受電壓試驗應按相關規(guī)定的試驗方法進行。濕操作沖擊耐受電壓試驗應所規(guī)定的試驗方法進行。材料試驗傘套材料新產(chǎn)品試制、定型或正常生產(chǎn)的產(chǎn)品，可*對一種型式的高壓U型環(huán)進行所規(guī)定傘套材料的型式試驗。*當傘套材料配方及工藝改變時，所規(guī)定的型式試驗中的各項必須重新進行全部項目的試驗。U型環(huán)要承受彎矩，故必須計算抗彎強度。長沙重型u型環(huán)規(guī)格</p><p
