Txhawm rau crimp ob sab splice davhlau ya nyob twg, peb yuav tsum tau them sai sai rau qhov zoo. Hauv IPC-A-620, muaj tshooj los txhais cov spec.
Hom phiaj - Chav Kawm 1,2,3
• Kho xim-coded tshav kub shrinkable tes tsho siv (A).
• Thaum tshav kub kub shrinkable tes tsho yog nyob rau hauv lub ferrule.
• Meltable sealing rings tau ntws.
Txais tau - Chav Kawm 1,2,3
• Qhov kawg ntawm cov xov hlau tsis txhob thim tawm ntawm cov hlau nres. Cov hlau yog pom
los ntawm kev tshuaj xyuas qhov rais ( xub).
• Hlau rwb thaiv tsev qhov sib txawv yog tsawg tshaj li ob tug hlau diameters nrog rau
rwb thaiv tsev.
• Bellmouth muaj pov thawj.
Txais tau - Chav Kawm 1,2,3
• Hlau rwb thaiv tsev qhov sib txawv yog nyob rau hauv ob tug hlau diameters nrog rau
rwb thaiv tsev ntawm ob qhov kawg (tsis qhia).
• Thaum tshav kub kub shrinkable lub tes tsho xaus yog kaw rau cov hlau rwb thaiv tsev
(tsis muaj xov hlau tsis raug).
Txais tau - Chav Kawm 1,2,3
• Crimp indents yog tig (tsuas yog seamless splices).
Txais tau - Chav Kawm 1

• Thaum tshav kub kub shrinkable lub tes tsho tsis yog nruab nrab, lub tes tsho xaus
sealed rau cov hlau rwb thaiv tsev.
Tsis zoo - Chav Kawm 1,2,3
• Hlau rwb thaiv tsev txuas mus rau hauv cov hlau crimp chim chim (A).
• Crimp indent tawm ntawm qhov kawg ntawm qhov sib txuas (B).
• Hlau kawg tsis pom los ntawm lub qhov rais tshuaj xyuas
(C).
• Hlau rwb thaiv tsev qhov sib txawv yog ntau tshaj li ob txoj kab uas hla
suav nrog rwb thaiv tsev (D).
• Thaum tshav kub kub shrinkable lub tes tsho tsis overlap ob lub rwb thaiv tsev
qhov khoob (tsis qhia).
Tsis zoo - Chav Kawm 1,2,3
• Cov hlua hlau txuas tawm ntawm lub qhov rais tshuaj xyuas.
Tsis zoo - Chav Kawm 1,2,3
• Cov hlua hlau tau tho lub tes tsho thaum tshav kub kub shrinkable.
