Extension rings yog ib hom kev sib txuas kho vajtse siv los txuas ob lub U-shackles los yog koom tes nrog lwm cov khoom siv sib txuas, xws li Z-hom clevis daim hlau, thaum kawg txuas nrog ntauwd thiab cov insulator. Cov kev qhia tshwj xeeb ntawm cov nplhaib txuas ntxiv yog PH-0780 thiab PH-10100. Nws nominal tawg load yog 70-100 kN. Extension rings feem ntau yog ua los ntawm cov khoom siv hlau Q235 carbon steel, uas muaj zog thiab hnav tsis kam. Txij li thaum ib puag ncig uas siv cov nplhaib txuas ntxiv feem ntau yog cov kab hluav taws xob ntawm cov ncej hluav taws xob, txhawm rau kom lawv tuaj yeem tiv nrog ntau qhov chaw ib puag ncig, kev siv thev naus laus zis tau txais kev kub kub forging, thiab kev kho saum npoo yog kub-dip galvanizing. Xws li cov txheej txheem ntau lawm tuaj yeem ua rau kom muaj kev pabcuam lub neej ntawm cov khoom lag luam thiab ua kom lub zog ruaj khov ntawm lub zog.
