OPGW optical cable feem ntau yog siv rau ntawm 500KV, 220KV, 110KV voltage theem kab, thiab feem ntau yog siv rau cov kab tshiab vim kab hluav taws xob tsis ua haujlwm, kev nyab xeeb thiab lwm yam.
Ib qho kawg ntawm cov xaim hauv av ntawm OPGW optical cable txuas nrog rau qhov sib txuas txuas, thiab lwm qhov kawg yog txuas nrog hauv av raws li cov kab sib txuas ntauwd.Cov kab txuas txuas txuas yog ntsia rau ntawm OPGW kho qhov muag cable downwire ntawm cov kab sib txuas ntauwd ntawm lub substation kom txuas OPGW optical cable downwire rau hauv av.Nyob rau tib lub sijhawm, cov xaim hauv av thiab OPGW kho qhov muag cable ua rau tus pej thuam ntawm cov kab sib kis tau muab tso rau hauv cov raj tiv thaiv, thiab cov khoom siv kho qhov muag fiber ntau yog qhov zoo tshaj plaws los siv tus qauv.
1. Peb-point grounding method ntawm cement ncej
1) Sab saum toj kawg ntawm lub qhov rooj ncej yog txuas nrog steel tub ntxhais aluminium stranded hlau, ib kawg yog txuas nrog OPGW optical cable nrog ib tug parallel zawj clip, thiab lwm yam kawg yog crimped nrog ib tug txhuas qhov ntswg thiab ces txuas nrog lub grounding lub cev. nrog hlau bolts.
2) Txuas cov tub ntxhais hlau tus pin tso tseg hlau nyob rau hauv pem hauv ntej ntawm lub redundant cable rack, ib kawg ntawm uas yog txuas nrog OPGW optical cable nrog rau parallel zawj clamp, thiab lwm yam kawg yog kev cob cog rua thiab tsau nrog lub grounding ca steel siv nrog hlau. clamps thiab hlau bolts.
3) Siv steel-aluminium stranded hlau los txuas ntawm lub cable khib thiab lub thawv splice, ib kawg yog txuas nrog OPGW optical cable nrog rau qhov sib npaug zawj clamp, thiab lwm qhov kawg yog txuas nrog lub hauv av tiaj tus steel siv nrog steel clamps thiab hlau bolts.
2. Peb-point grounding txoj kev ntawm steel yeeb nkab ncej
1) Sab saum toj kawg ntawm lub qhov rooj ncej yog txuas nrog steel tub ntxhais aluminium stranded hlau, ib kawg yog txuas nrog OPGW optical cable nrog ib tug parallel zawj clip, thiab lwm yam kawg yog crimped nrog ib tug txhuas qhov ntswg thiab ces txuas nrog lub grounding lub cev. nrog hlau bolts.
2) Siv steel-cored aluminium stranded hlau los txuas rau pem hauv ntej ntawm qhov seem cable khib, ib kawg ntawm txoj phuam yog txuas nrog OPGW optical cable nrog ib qho sib npaug zawj clip, thiab lwm qhov kawg yog txuas nrog kev sib txuas hauv av ntawm cov hlau. -cored txhuas hlau nrog ib tug sib npaug grooved hlau clip.
3. Peb-point grounding txoj kev ntawm pej thuam
1) Sab saum toj kawg ntawm lub qhov rooj ncej txuas nrog steel-cored aluminium stranded hlau.Ib qho kawg ntawm qhov sib npaug ntawm cov hlua hlau txuas txuas nrog OPGW optical cable, thiab lwm qhov kawg ntawm lub qhov ntswg aluminium yog crimped thiab tom qab ntawd txuas nrog lub cev hauv av nrog cov hlau bolts.
2) Txuas nrog steel-aluminium stranded hlau nyob rau hauv pem hauv ntej ntawm qhov seem cable khib, thiab txuas ib kawg nrog OPGW optical cable nrog ib tug parallel zawj clamp.Lwm qhov kawg ntawm lub qhov ntswg aluminium yog crimped thiab txuas nrog lub pej thuam nrog hlau bolts.
3) Siv steel-aluminium stranded xaim los txuas ntawm lub thav duab cable thiab lub thawv splice.Ib qho kawg yog txuas nrog OPGW optical cable nrog rau qhov sib npaug ntawm qhov zawj clamp, thiab lwm qhov kawg yog crimped nrog lub qhov ntswg aluminium thiab tom qab ntawd txuas nrog cov hlau ntauwd nrog hlau bolts.
