Cov hlau lead-down clamp yog siv los ua cov kab hluav taws xob kho qhov muag thiab kho qhov kho qhov muag cable thaum nws yog jumpered, uas txhim kho qhov kev ua tau zoo ntawm cov clamp. Nws yog tsuas yog siv rau txoj kab kev sib txuas lus ntawm cov khoom siv hluav taws xob tshiab uas tsim los ntawm high-voltage fais fab kis ntawm 35kv thiab siab dua.
Lub stainless hlau raj thiab cable core stranding tsim yog tsim nyog, thiab cov optical fiber yog redundant.
Qhov ntev yog qhov tseeb; tag nrho-dielectric self-supporting optical cable (ADSS) raug tshem tawm ntawm tus ncej ntauwd nrog txoj kab tig lub kaum sab xis tsawg dua 25 °.
Nta
1.It yog tsim rau hom pob txha, txheej stranded hom, nqaj raj hom armored thiab hloov tau yooj yim hauv kev siv.
2. Dielectric zog: 15kv DC, tsis tawg hauv 2 feeb.
3.Txhim kho qhov muag cable uas tau kos los yog nce ntawm tus ncej mus rau tus ncej kom nws tsis tuaj yeem shaken
4.Conditions: thawj thiab kawg ncej, txuas ncej, thiab lwm yam ntawm cov kab hluav taws xob kho qhov muag.
5.Siv: Feem ntau nruab ib qho txhua 1.5 meters.
Daim ntawv thov
1. Rau fiber ntau optic cable txuas ntauwd, ntauwd cable lead davhlau ya nyob twg thiab nruab nrab nyob rau hauv lub arched ib feem ntawm lub nro cable ntauwd tsau, txhua 1.5 meters nrog ib tug txheej ntawm general, lwm yam kev xav tau kuj siv tau ib qho chaw ruaj.
2. Lub down lead clamp yog siv nyob rau hauv lub immobility ntawm OPGW / ADSS ntawm ncej / tower. Nws yog tsim rau riveting ntawm fiber ntau thaum dhia lossis nqes txhuas. Thiab nws tau nquag ntsia txhua txhua 1.5 mus rau 2 meter txhua teeb. Qhov no clamp bears qhov zoo tshaj plaws ntawm kev yooj yim installation, adjustable ntau yam yuav haum rau txawv Dia.
