Qhov loj cable txhais li cas?

Thaum muas cov cables thiab cables, peb feem ntau hnov ​​1.5, 2.5, 4, 6, thiab 10 square cables. Yog li cas lub square ntawm cables thiab cables txhais li cas? Nws txhais li cas? Muaj pes tsawg square cables thiab cables koj yuav tsum xaiv thaum kho koj lub tsev? Tus editor ntawm Hongzhou Hlau thiab Cable yuav tham nrog koj txog cables hnub no. Lub square ntawm txhais li cas?

1. Lub ntsiab lus ntawm square ntawm cov hlau

Cov neeg feem ntau hais tias 1.5, 2.5, 4, 6 thiab 10 square kab. Tus nqi ntsuas no yog hais txog qhov chaw hla ntu ntawm cov kab sib kis. Ib tug 1.5 square hlau yog ib tug hlau nrog ib tug ntoo khaub lig-sectional cheeb tsam ntawm 1.5 mm2. Thaum peb xaiv cables thiab cables, kuj tseem muaj lwm qhov taw qhia tus nqi - cable ampacity. Lub peev xwm nqa tam sim no yog hais txog tus nqi tam sim no uas tus neeg xyuas pib hluav taws xob tuaj yeem thauj mus los tsis tu ncua nyob rau hauv cov xwm txheej tshwj xeeb thiab ntu ntu ntawm kev lag luam, tsis tas yuav ua rau nws qhov kub thiab txias ambient siab tshaj tus nqi tus qauv. Qhov kev nyab xeeb tam sim no nqa lub peev xwm ntawm tooj liab tub ntxhais hlau feem ntau yog 5 ~ 8A / hli, thiab qhov kev nyab xeeb tam sim no nqa lub peev xwm ntawm txhuas hlau cable yog 3 ~ 5A / mm

2. Yuav ua li cas xaiv cov cables thiab cov xov hlau rau kev kho kom zoo nkauj hauv tsev

Piv txwv li, ua ke nrog kev muaj tiag, yog tias koj xav tau txuas lub cuab yeej siv hauv tsev 1000 watt, lub zog tawm tswv yim=1000/220=txog 5 amps. Feem ntau, cov square tam sim no nqa peev xwm yog li 5A-8A, yog li cov square xaim txaus. Lawm, yog tias nws yog txhuas, nws yuav tsum yog 1.5 square inches. (Cov ntaub ntawv saum toj no tsuas yog siv rau kev siv xwb)

1. Hauv kev kho kom zoo nkauj hauv tsev, 1.5 square kab feem ntau siv los ua cov kab teeb pom kev zoo kom ntseeg tau tias lub zog tso zis ntawm lub teeb nyob ib puag ncig 2500 watts. Hauv qee chav da dej nrog kev sib koom ua ke Yuba, cov zis hluav taws xob zoo li yuav yog ob peb puas watts lossis txawm tias ob peb kilowatts. Nws tau thov kom hloov cov teeb pom kev zoo rau 2.5 square kab los xyuas kom meej tias kev nyab xeeb ntawm lub teeb thiab kev sib xyaw Yuba hauv thaj tsam ntawm 4000 watts.

2. Lwm cov khoom siv hauv tsev feem ntau siv 4 cov xov hlau square, uas tuaj yeem txuas nrog cov khoom siv hauv tsev ntawm 220V * 32A=7000W watts, thiab siv tau zoo tib lub sijhawm.

Teeb pom kev zoo fixtures thiab socket thaiv daim ntawv thov. Nws tsis yog qhov tsim nyog los nqa hluav taws xob los ntawm cov kab teeb pom kev zoo thiab siv nws ua qhov hluav taws xob hluav taws xob. Cov qauv thiab cov qauv yog qhov tsim nyog rau kev nyab xeeb.

3. Nws raug nquahu kom cais cov xaim ntawm lub tshuab cua txias thiab lub txee hluav taws xob. Txij li thaum feem ntau ntawm cov vaj tse nyob txuas nrog hauv cov koob, kev tshaj tawm tsis pom zoo, uas yuav ua rau kom muaj kev laus thiab ua rau muaj kev pheej hmoo. Cov cua txias hauv nruab nrab siab tshaj 3 units feem ntau siv ib leeg-ntxhais xov hlau tshaj 4 square meters.

4. Instantaneous water heaters yog nrov rau lawv lub zog txuag, me me, thiab zoo nkauj tsos. Nyob rau theem no, nws cov koob meej yog ceev heev, tab sis nws kuj siv ntau lub zog hluav taws xob thaum lub sijhawm ua haujlwm, xws li 3000 watts txog 6000 watts, 7500 watts, 8000 watts thiab ntau dua. Yog li ntawd, thaum sib sau ua ke lub tshuab rhaub dej tam sim, yog tias nws tshaj 6000 watts, nws yuav tsum tau muab cais tawm ntawm lub txee hluav taws xob. Yog tias nws siab tshaj 7000 watts, nws yog ib qho tsim nyog yuav tsum tau siv 6 square xov hlau, thiab xaiv ib qho kev tiv thaiv hluav taws xob los tiv thaiv hluav taws xob hloov pauv raws li tus nqi tam sim no. . Yog tias koj xaiv cov cables thiab cov xov hlau, nws yuav tsum tsis txhob raug nqi thiab pheej hmoo pov thawj hauv kev siv.

Multi-core tooj liab hlau ntawm 5.10 square meters thiab saum toj no yog lub teb chaws tus qauv hlau, uas yog ib tug multi-core tooj liab hlau, uas yog feem ntau siv nyob rau hauv lub tsev channel kab.
