Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm kev lag luam kev sib txuas lus, cov khoom siv hlau thiab cable kuj tau tsim los ntawm kev xav tsis thoob. Kev siv cov cables kuj tau txhim kho zoo heev thiab hloov tau yooj yim heev. Cov kab hluav taws xob tuaj yeem raug mob ntawm lub xov tooj cable nrog lub vojvoog dabtsi yog khoov Ntau dua lossis sib npaug li 20D, qhov twg D yog sab nraud ntawm lub cable. Qee cov cables tsis muaj pa taws thiab tsis muaj tshuaj lom thaum hlawv, thiab cov ntaub ntawv insulating yog "tsis-flammable" cov ntaub ntawv inorganic. Nyob rau hauv cov txheej txheem combustion, tsis muaj cov pa phem yuav raug tsim, los yog nws yuav ua rau cov pa phem thib ob. Nws yog hu ua ib puag ncig tus phooj ywg ntsuab khoom. Kev ruaj ntseg zoo. Ntxiv nrog rau cov khoom siv hluav taws xob ib txwm muaj, cov hluav taws xob tua hluav taws kuj tseem tuaj yeem pib cov cuab yeej tua hluav taws hauv cov nplaim taws kom txo tau qhov hluav taws kub. Nyob rau tib lub sijhawm, nws yog qhov tshwj xeeb rau kev nyab xeeb ntawm tus kheej. Copper sheath yog ib tug zoo conductor thiab zoo tshaj plaws grounding hlau. Nws txuas mus rau tag nrho ntev ntawm cable, uas zoo heev txhim kho qhov rhiab heev thiab kev ntseeg siab ntawm kev tiv thaiv hauv av. Thiab nws muaj lub neej ua haujlwm ntev, cov khoom siv inorganic insulating, kub tsis kam, tsis yooj yim rau kev laus, thiab nws cov kev pab cuam lub neej yog ntau zaus ntev dua li cov organic insulated cables. Raws li kev ua haujlwm ib txwm muaj, nws lub neej kev pabcuam tuaj yeem sib npaug rau kev pabcuam lub neej ntawm lub tsev.
Kev ruaj ntseg yuav tsum tau thaum lub sij hawm installation:
1. Thaum cov cables hla ib leeg, cov kab hluav taws xob high-voltage yuav tsum nyob hauv qab cov kab hluav taws xob tsawg. Thaum ib qho ntawm cov cables dhau los ntawm cov khoom siv tiv thaiv cov kav dej los yog sib cais los ntawm ib qho kev faib tawm hauv 1 meter ua ntej thiab tom qab tus ntoo khaub lig, qhov tsawg kawg nkaus qhov kev ncua deb yog 0.25 meters.
2. Thaum txoj kab txuas mus los yog hla cov yeeb nkab kub, qhov tsawg kawg nkaus ntawm txoj kab sib txuas thiab kab hla yog 0.5m thiab 0.25m, raws li.
3. Thaum cov cables hla txoj kev tsheb ciav hlau lossis txoj kev loj, cov kav dej yuav tsum tau siv los tiv thaiv, thiab cov kav dej yuav tsum tau ntev tshaj li ntawm txoj kab los yog txoj kev nto ntawm ntau tshaj 2 meters.
4. Qhov kev ncua deb ntawm lub cable thiab lub hauv paus ntawm lub tsev yuav tsum xyuas kom meej tias lub cable yog faus sab nraum cov dej xoob ntawm lub tsev. Thaum lub cable nkag mus rau hauv lub tsev, cov kav dej yuav tsum tau siv los tiv thaiv, thiab cov yeeb nkab tiv thaiv yuav tsum tau tshaj lub tsev cov dej tawg.
5. Qhov kev ncua deb hauv av ntawm qhov ncaj qha faus cable thiab cov khoom siv hauv av yuav tsum yog 0.25-0.5 meters, thiab qhov faus qhov tob ntawm qhov ncaj qha faus cable yuav tsum tsis txhob tsawg dua 0 .7 meters, thiab nws yuav tsum tau faus rau hauv permafrost.
