Raws li cov qauv tsim thiab cov txheej txheem kev teeb tsa, qhov nro clamps ntawm lub hwj chim kab fittings tuaj yeem muab faib ua plaub hom: compression hom nro clamps, bolt hom nro clamps, wedge hom nro clamps, thiab pre twisted nro clamps.
Compression hom nro clamps feem ntau yog tsim los ntawm txhuas (aluminium alloy) hlab thiab steel anchors. Cov hlau thauj tog rau nkoj yog siv los txuas thiab thauj tog rau nkoj cov tub ntxhais hlau ntawm cov hlau tub ntxhais hlau aluminium stranded hlau, thaum lub txhuas (aluminium alloy) raj siv los txuas cov txhuas (aluminium alloy) hlau ib feem ntawm cov hlau. Aluminium (aluminium alloy) raj thiab hlau thauj tog rau nkoj yog raug rau cov yas deformation nyob rau hauv siab, yog li integrating lub clamp nrog cov hlau tag nrho. Compression hom nro clamps siv rau hauv av xaim feem ntau yog tsim los ntawm steel anchors. Lub installation ntawm compression hom nro clamps feem ntau muab faib ua ob txoj kev: hydraulic thiab explosive siab. Lub steel thauj tog rau nkoj ntawm nro clamp yog forged.
Bolt hom nro clamps siv lub ntsug siab ntawm U-puab screws thiab kev sib txhuam cov nyhuv tsim los ntawm wavy zawj ntawm lub clamp los kho cov xov hlau. Lub cev thiab siab phaj ntawm hom hlau clamp no yog ua los ntawm malleable cam khwb cia hlau. Haum rau kev txhim kho aluminium stranded hlau, tooj liab stranded hlau, thiab steel cored aluminium stranded hlau nrog me me thiab nruab nrab cross-section.
Lub nplhaib-shaped nro clamp siv qhov sib cais quab yuam ntawm lub npoo los xauv cov hlau (hauv av xaim) hauv lub clamp. Cov hlau strand yog khoov rau hauv tib yam li lub npoo thiab ntsia rau hauv lub clamp. Thaum lub steel strand raug quab yuam, lub npoo thiab cov hlau strand swb raws lub clamp lub tog raj kheej phab ntsa ntawm lub qhov hluav taws xob clamp, ua nruj dua thiab maj mam kaw. Lub cev clamp thiab wedges yog ua los ntawm malleable cam khwb cia hlau. Siv rau kev txhim kho steel strands, fastening av xaim, thiab rub cov xov hlau rau cable yees. Installation thiab tshem tawm yog ob qho tib si kuj yooj yim.
Lub pre twisted nro clamp yog tsim los ntawm cov hlau pre twisted hlau thiab txhawb nqa accessories, uas nro cov hlau (hauv av hlau) ntawm lub nro ntauwd.
