GL Fiber muab kev kho vajtse fittings rau kev teeb tsa nrog ADSS fiber cable txhawb nqa ntawm tus ncej. Lub cable nyob rau hauv ntau lub raj xoob uas muaj cov dej-resistant filling compound los yog tsim rau cov dej thaiv nrog cov dej thaiv cov khoom hauv lub cable. Lub cable siab yog tensile los ntawm aramid yarns thiab FRP lub zog tus tswv cuab pas nrig hauv. Sab nrauv sheath ua los ntawm HDPE. Tau kawg, muaj ntau qhov tshwj xeeb ntawm ADSS fiber ntau cables. Cia peb saib luv luv ntawm ADSS cable ntawm 120m ncua. Cov hauv qab no yog cov ntsiab lus tshwj xeeb parameter:
