Kev Npaj Ua Ntej
Npaj cov cuab yeej tshwj xeeb ua ntej: cov no suav nrog torque wrenches, insulated hlau strippers, crimping cov cuab yeej, multimeters, thiab lwm yam. Ib txhij, sib sau consumables xws li cable accessory lub cev, sealing compounds, hluav taws xob daim kab xev, thiab waterproof daim kab xev uas phim cov cable specifications. Xyuas kom tseeb tias qhov chaw tsim kho yog qhuav thiab zoo- qhov cua, thiab tsis txhob ua haujlwm thaum huab cua tsis zoo xws li los nag, daus, lossis cua daj cua dub. Cov cim ceeb toom yuav tsum tau muab tso rau hauv siab - qhov chaw ua haujlwm voltage. Ua ntej ua haujlwm, xyuas kom meej tias cov qauv cable, hla- ntu ntu, thiab cov khoom siv tsis sib xws los tiv thaiv kev siv cov khoom siv tsis raug. Kev ua haujlwm siab -voltage yuav tsum tau ua tshwj xeeb los ntawm cov kws hluav taws xob tuav daim ntawv pov thawj kev ua haujlwm tshwj xeeb.
Ua ntej-Kev tshuaj xyuas kev tsim kho
Ua ntej, tshuaj xyuas lub cev lub cev ntawm lub cable: paub meej tias cov txheej txheej sab nrauv thiab rwb thaiv tsev tsis muaj cov cim qhia ntawm kev puas tsuaj, noo noo ingress, lossis corrosion. Tom ntej no, tshem tawm thiab tshuaj xyuas cov khoom siv cable kom ntseeg tau tias lub ntim khoom tsis zoo thiab txhua yam khoom muaj nyob thiab tsis muaj kev puas tsuaj. Rau siab -voltage cable ua hauj lwm, nws yog ib qho yuav tsum tau ua ntej kom paub tseeb tias cov kab yog de-energized thiab mus txuas grounding nyob ntawm tej; kev tsim kho tsuas yog ua tiav thaum nws tau lees paub tias tsis muaj kev pheej hmoo ntawm hluav taws xob poob siab. Rau cov kab hluav taws xob qis qis, cov khoom siv hluav taws xob sab saud yuav tsum raug txiav, thiab cov ntawv ceeb toom yuav tsum tau tshaj tawm.
Main Lub cev Installation
Ua raws li cov stripping qhov ntev tau teev tseg hauv phau ntawv qhia khoom, ua ntu zus tshem tawm cov hlua sab nrauv, steel armor (rau armored cables), thiab sab hauv sheath. Thaum lub sijhawm ua haujlwm no, kev saib xyuas kev noj qab haus huv kom tsis txhob muaj kev puas tsuaj rau cov kab hluav taws xob lossis cov txheej txheem tseem ceeb. Tom qab ntawd, crimp lub connector terminals (rau cable terminations) los yog kev twb kev txuas tes tsho (rau cable pob qij txha). Siv lub torque wrench kom ceev cov bolts rau qhov tshwj xeeb torque qhov tseem ceeb los ntawm cov khoom tsim khoom; qhov no tiv thaiv dhau - zawm- uas tuaj yeem ua rau cov conductors puas tsuaj - lossis qis dua - nruj - uas tuaj yeem ua rau tsis zoo hluav taws xob sib cuag thiab kub dhau.
Txheej txheem sealing
Qhov no yog ib theem tseem ceeb rau kev tiv thaiv ingress ntawm noo noo thiab dej nag. Ua ntej, ua kom huv si huv si txhua qhov chaw sib txuas uas tsim los rau kev sib khi kom ntseeg tau tias lawv tsis muaj plua plav thiab dej stains. Tom qab ua ntawv thov tshwj xeeb sealing compound, nruab lub sealing sheath thiab qhwv lub cheeb tsam nrog waterproof hluav taws xob daim kab xev. Rau kev tshem tawm cov kab hluav taws xob sab nraum zoov, cov ntaub thaiv npog los nag yuav tsum tau teeb tsa kom tsis txhob muaj qhov sib txawv ntawm qhov chaw kaw, uas tuaj yeem ua rau muaj kev cuam tshuam tsis zoo.
Kev Ntsuas Kev Ua Haujlwm thiab Kev Txais
Ntsuam xyuas cov rwb thaiv tsev tsis kam ntawm cov khoom siv cable. Rau qis- hluav taws xob cables, lub rwb thaiv tsev tiv thaiv yuav tsum tsis pub tsawg tshaj 0.5 MΩ / km; rau siab -voltage cables, nws yuav tsum ua raws li cov kev cai ntawm *Standard for Construction and Acceptance of Cable Lines in Electrical Installation Engineering* (GB 50168-2018). High- cov khoom siv hluav taws xob kuj tseem yuav tsum tau txais lub zog-zaus zaus tiv thaiv qhov ntsuas hluav taws xob. Thaum tag nrho cov kev ntsuas raug txheeb xyuas raws li kev ua raws, sau cov ntaub ntawv tsim kho thiab ua tiav cov txheej txheem lees paub.
Ncej -Kev Tiv Thaiv thiab Kev Tshawb Fawb
Ruaj ntseg fasten lub installation accessories kom tiv thaiv kev puas tsuaj los ntawm sab nraud lub cev. Accessories ntsia sab nraum zoov yuav tsum tau cim kom meej meej thiab raug soj ntsuam raws sij hawm tom ntej los xyuas cov cim ntawm kev laus nyob rau hauv lub sealing Cheebtsam, raws li zoo raws li anomalies xws li overheating los yog deformation; txhua yam kev phom sij uas raug txheeb xyuas yuav tsum tau hais kom sai.
