1. Kev tsim kho txoj haujlwm: ua ntej ua haujlwm ruaj khov thiab ua raws
Hauv kev tsim kho cov phiaj xwm (piv txwv li lub tsev lag luam, thaj chaw nyob hauv, lossis cov txheej txheem pej xeem), thw clesles feem ntau yog siv rauCov xaim hluav taws xob ib ntus thaum kev tsim khothiabCov ceg ceg tas li hauv cov qauv tiav lawmCov. Qhov kev sib tw ntawm no suav nrog kev siv rau kev tsim kho kom zoo, ua raws li cov kab ke tsim tsev (piv txwv li cov hauv paus, lossis sab nrauv cov cheeb tsam).
Cov Ntawv Thov Thov:
Lub zog hluav taws xob ib ntus: Thaum kev tsim kho, thatr npog cov cuab yeej siv hluav taws xob uas muaj zog (piv txwv li cov kav dej, ua kom sib xyaw ua ke) thiab teeb pom kev ib ntus. Lawv cov dej tsis kam yog tseem ceeb ntawm no- Kev Siv Av feem ntau muaj puddles lossis damp av, thiab txheem th 80 pvc txwv tsis pub muaj kev sib cuag dej luv luv los ntawm kev sib cuag dej luv luv.
Cov ntaub qhwv hluav taws xob tas mus li hauv cov tsev tshiab: For residential complexes or office buildings, THW cables are installed in walls, conduits, and ceiling cavities to power outlets, lighting, and low-load systems (eg, intercoms). Thw-2 (tus qauv hloov kho tshiab nrog kev txhim kho cov tshuab lub zog) yog qhov nws tawm tsam ntawm no, raws li nws tiv thaiv kev ua haujlwm los ntawm cov khib nyiab zoo dua tus qauv thw.
Cov lus qhia xaiv rau kev tsim kho:
Khij Qhov Code Ua Raws: Ua kom cov cable thw Piv txwv li, NEC yuav tsum tau 75℃- bising cables, tab sis zam tsis txhob siv cov chaw ntub dej (piv txwv li, thhn) hauv cov hauv paus, hauv qab.
Xaiv thw - 2 rau cov chaw ua paug loj: Yog tias cov kab ke yuav raug rub los ntawm cov khoom siv hlau hlau lossis nruab ze rau cov chaw tsim khoom nrog kev tsim kho hnyav, xaiv rau thw-2 hloov ntawm tus qauv thw kom tiv thaiv kev rwb thaiv tsev puas tsuaj.
Sib phim Ampacity Mus Thauj: Rau cov cuab yeej siv hluav taws xob ib ntus (piv txwv li, ib qho kev xyaum 15-amp), A AWG Thw Cable (Ampacity: 15 amps) suffices. Rau cov khoom siv hluav taws xob tas mus li hauv chaw ua haujlwm (kev siv hluav taws xob ntau), siv 12 AWG Thw (20 amps) kom tsis txhob overheating.
2. Kev txhim kho hauv tsev: tsom rau kev nyab xeeb thiab kev tswj hwm
Hauv cov phiaj xwm txhim kho hauv tsev (piv txwv li kev hloov pauv hauv tsev (EG, kev hloov kho chav dej, cov khoom siv hauv qab daus, lossis cov hluav taws xob ntxiv, lossis cov khoom siv hluav taws xob tshiab. Lub ntsiab tseem ceeb ntawm no yogKev nyab xeeb hauv thaj chaw noo(piv txwv li, chav dej) thiabCompatibility nrog cov khoom siv hauv tsev(xws li, cov tub yees, microwaves).
Cov Ntawv Thov Thov:

Piv txwv li, thaum ntxiv cov qhov hluav taws xob tshiab ze ntawm chav dej zaum hauv chav da dej, this yuav khiav ntawm lub phab ntsa yam tsis muaj kev pheej hmoo ua dej rau cov rwb thaiv tsev.
Cov cuab yeej siv hluav taws xob thiab teeb pom kev zoo: Thaum hloov cov xaim rau lub microwave (10-15 amps) lossis lub amps qab nter (5-10 amps), txheem thw cables (14 awg lossis 12 AWG) ua haujlwm zoo. Rau cov nra hnyav (piv txwv li, lub qhov rai ac chav nrog 20 amps), siv 12 www thw kom phim cov ampacity yuav tsum tau.
Txoj kev nqaim: For tight areas (eg, wiring behind a kitchen cabinet or in a narrow conduit), THW-N (the thin-insulation, flexible model) is ideal. Nws cov rwb thaiv tsev thinner thiab hloov tau cov neeg coj hloov pauv haum rau hauv cov chaw cramped yam tsis muaj kev cuam tshuam txog 75 degras Kub tsis kam.

Xaiv rau cov qauv thw rau feem ntau cov phiaj xwm: Rau cov kev hloov kho dav dav (piv txwv li, ntxiv qhov hluav taws xob hauv chav nyob lossis hloov chav pw teeb pom kev zoo), kev hloov pauv ntawm chav pw ntawm wire {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}. Reserve Thw {{4 4}} n rau qhov chaw nqaim thiab thw-2 tsuas yog muaj kev ntxhov siab hauv lub cev (piv txwv li, qab lub thawv ntawv loj).
Sau cim rau cov khoom siv rau yav tom ntej: Thaum khiav thw cables thaum lub sijhawm rov qab, sau npe rau lawv (piv txwv li chav dej "lossis" Qhov no txwv tsis pub muaj kev puas tsuaj rau kev puas tsuaj hauv tsev.
3. Muaj cov ntawv thov: Sib npaug
Hauv cov chaw muaj kev nyab xeeb, cov qoob loo yuav txwv rauTeeb muaj kev siv(Xws li, kev ua zaub mov noj, electronics sib dhos cov kab) vim lawv li 75 Degurve Kub Ntsuas. Lawv tsis haum rau cov khoom lag luam hnyav (piv txwv li cov motors hnyav) lossis siab}}}}} huab cua tsis xav tau.

Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob: Tsawg {{{- voltage Systems (piv txwv, LED teeb pom kev zoo rau kev tswj hwm, sensor xaim rau thew - n cables. Lawv cov rwb thaiv nyias nyias thiab yoog raws lawv kom haum rau cov chaw nruj ntawm cov tshuab, thiab lawv qhov siab tshaj plaws rau cov khoom siv hluav taws xob tsawg {}} voltage xav tau ntawm cov khoom siv hluav taws xob.
Lub tsev rau khoom teeb pom kev zoo thiab kev nyab xeeb: Rau cov tsev muag khoom nrog kev tswj hwm kub (20 {{}} 30 degree), thaw cables zog overhead teeb pom kev zoo thiab cov koob yees duab kev nyab xeeb. Lawv cov nqi pheej yig ua rau lawv tus nqi -} Siv cov xov hlau zoo rau kev tiv thaiv cov xaim hluav taws xob lossis cov khoom siv HVAC (piv txwv li, los ntawm HVAC cov tshuab).
Xaiv cov lus qhia rau kev siv:
