Lub hauv paus ntsiab lus ntawm kev xaiv tus naj npawb ntawm Cable Cores

Txhua yam hauv ntiaj teb no muaj lawv tus yam ntxwv thiab qib. Ntxiv mus, cov khoom siv hlau thiab cable tau siv dav thiab muaj ntau yam. Txawm hais tias koj nyob hauv kev lag luam, nws tsis yog qhov dav. Niaj hnub no, Jin Huanyu xaim thiab cable editor qhia nrog koj lub hauv paus ntsiab lus ntawm kev xaiv cov xov tooj ntawm cable cores.

1.Thaum qhov nruab nrab nruab nrab ntawm 1kV thiab hauv qab fais fab mov yog ncaj qha mus rau hauv av, thiab cov hlau tiv thaiv thiab nruab nrab ntawm peb -theem Circuit Court sib koom tib tus neeg xyuas pib, plaub core cable yuav tsum raug xaiv; Thaum cov hlau tiv thaiv thiab cov hlau nruab nrab yog sib cais, tsib core cable yuav tsum raug xaiv. Thaum lub grounding ntawm qhov raug conductive ib feem ntawm lub hwj chim txais khoom thiab lub grounding ntawm lub hwj chim system yog cais, plaub core cables yuav tsum tau xaiv.

2.Thaum qhov nruab nrab nruab nrab ntawm 1kV thiab hauv qab fais fab mov yog ncaj qha hauv av, thiab cov xaim tiv thaiv thiab cov xaim nruab nrab hauv ib qho -theem Circuit Court sib koom tib tus neeg xyuas pib, ob lub core cable yuav tsum raug xaiv; Thaum cov hlau tiv thaiv thiab cov hlau nruab nrab sib cais, peb cov tub ntxhais cable yuav tsum raug xaiv. Thaum lub grounding ntawm qhov raug conductive ib feem ntawm lub hwj chim txais khoom thiab lub grounding ntawm lub hwj chim system yog cais, ob tug tub ntxhais cables yuav tsum tau xaiv.

 3.In 3 35kV three-phase power supply circuit, when the circuit or cable with large working current is laid underwater, three single core cables can be selected for each circuit; In addition to the above cases, three core cables shall be selected; The three core cable can be of general turnkey type or the stranded structure of three single core cables.

4. Rau siab -voltage AC ib zaug -theem fais fab mov circuits xws li hluav taws xob, ob tug tub ntxhais cables los yog ob tug tub ntxhais cables yuav tsum raug xaiv rau txhua lub voj voog.

5. Rau qis-voltage DC fais fab mov Circuit Court, yuav tsum tau xaiv ob core cable; Ib leeg tub ntxhais cable kuj raug xaiv. Ib leeg tub ntxhais cable yuav tsum raug xaiv rau HVDC kis kab mob; Coaxial ob core cable kuj tuaj yeem xaiv rau hauv qab dej tso rau hauv Lake, hiav txwv, thiab lwm yam.

6. Nyob rau hauv 110kV peb-theem fais fab mov Circuit Court, peb ib leeg tub ntxhais cables tuaj yeem xaiv rau txhua lub voj voog, tshwj tsis yog tias peb cov tub ntxhais cables tuaj yeem xaiv tau thaum lawv muab tso rau hauv qhov chaw xws li pas dej thiab dej hiav txwv thiab cov cables. seem me me. Rau peb -theem fais fab mov circuits saum 110KV, peb ib leeg tub ntxhais cables yuav tsum raug xaiv rau txhua qhov lus teb.
