G652.d 12-core tus kheej txhawb nqa sab nraum zoov fiber optic cable tshaj tawm

Cov fibers optical 250 µm tau muab tso rau hauv cov raj xoob ua los ntawm cov yas high-modulus thiab puv nrog cov tshuaj tiv thaiv dej. 12 txog 96 cores.
FRP yog siv ua lub hauv paus tseem ceeb.
Cov raj xa dej xoob yog SZ-braided nyob ib ncig ntawm cov tswv cuab reinforcing.
Daim kab xev thaiv dej siv los qhwv cov tub ntxhais xoob. Cov polyethylene sheathing siv rau saum cov tub ntxhais cable ua ib daim npog sab nraud.

Cov yam ntxwv

1. Txoj kab uas hla me me, lub teeb yuag, 200 m ntau yam, thauj khoom tsawg txuas rau lub pej thuam.
2. Cov qauv tsis yog hlau, rwb thaiv tsev zoo, tiv thaiv xob laim.
3. Kev siv tshuab zoo heev, txawm tias muaj zog rau aramid fiber, nrog rau kev ywj pheej zoo dua.
4. Tiv taus kev phom sij thiab hluav taws xob xeb. Hloov tau raws li huab cua hnyav.
5. Nws tuaj yeem tsim tau yam tsis muaj hluav taws xob poob; kev puas tsuaj ntawm cov kab hluav taws xob yuav tsis cuam tshuam rau kev xa xov hluav taws xob ib txwm muaj.
6. Ib lub thawv sab nraud uas tiv taus hluav taws xob tau txais yuav los ua haujlwm kom muaj kev nyab xeeb hauv qhov chaw hluav taws xob (E) ≤25KV / m xwm txheej

Cov ntawv thov

1. Txhim cov xov hluav taws xob tshiab thiab qub rau ntawm tib lub ncej.
2. Lub sijhawm ntev, thaj chaw muaj hluav taws xob muaj zog, ntau lub suab xob quaj, thiab lwm yam.
