Basic Introduction Ntawm Hlau Thiab Cable

Basic qhia txog hlau thiab cable

Hlau thiab cable: Feem ntau yog ua los ntawm cov xov hlau sib tw los yog pawg ntawm cov xov hlau [tsawg kawg yog ob pawg hauv txhua pab pawg], zoo ib yam li cov hlua. Txhua txheej ntawm cov xov hlau yog insulated los ntawm ib leeg thiab feem ntau twisted nyob ib ncig ntawm ib qho chaw, nrog ib tug heev insulating npog npog tag nrho cov txheej txheej. Feem ntau yog siv rau kev sib kis, kev faib hluav taws xob hluav taws xob lossis kev xa hluav taws xob.

Hlau thiab cables yog tsim los ntawm plaub ntu hauv qab no

1, conductive hlau core: ua los ntawm high conductivity khoom (tooj liab los yog txhuas). Txhua lub tub ntxhais hlau tuaj yeem tsim los ntawm ib lossis ntau cov xov hlau sib tw ua ke raws li qhov yuav tsum tau muaj ntawm cable softness rau nteg tej yam kev mob.

2, txheej rwb thaiv tsev: siv los ua cov khoom siv hluav taws xob cable yuav tsum muaj cov rwb thaiv tsev siab. Cov ntaub ntawv rwb thaiv tsev feem ntau siv hauv cov cables yog roj-impregnated ntawv, PVC, polyethylene, crosslinked polyethylene, roj hmab thiab lwm yam.

3, sealing lub tsho: tiv thaiv cov tub ntxhais insulating hlau los ntawm kev siv tshuab, ya raws, ya raws, tshuaj, lub teeb thiab lwm yam kev puas tsuaj. Rau kev rwb thaiv tsev tsis muaj dej noo, txhuas lossis txhuas extruded foob tsho feem ntau siv.

4, kev tiv thaiv npog: los tiv thaiv lub sealing sheath los ntawm txhua yam kev puas tsuaj. Feem ntau, galvanized steel daim kab xev, steel hlau los yog tooj liab daim kab xev thiab tooj liab hlau yog siv los ua armor qhwv nyob rau hauv lub sheath (hu ua armored cable). Cov txheej armored tseem ua lub luag haujlwm ntawm hluav taws xob tiv thaiv thiab tiv thaiv kev cuam tshuam ntawm cov hluav taws xob sab nraud. Txhawm rau kom tsis txhob muaj kev xeb ntawm steel siv thiab steel hlau los ntawm ib puag ncig nruab nrab, lawv feem ntau coated nrog asphalt los yog qhwv ib ncig ntawm impregnated jute txheej los yog extruded polyethylene, PVC sheath.
