Thaum lub caij ntuj no, qhov kub thiab txias ntau qhov chaw qis heev, cov yeeb nkab dej yuav khov thiab tawg, cuam tshuam rau peb lub neej ib txwm muaj, ces koj xav tau cov kav dej cua sov thiab cov khoom siv rwb thaiv tsev kom tswj tau qhov kev ncig ntawm cov dej hauv cov yeeb nkab dej. Cov neeg siv khoom thaum yuav cov hluav taws xob tracing tropical feem ntau nug kom siv lub zog tropical, cov yeeb nkab 100 meters hauv qab no siv lub zog ntawm cov hluav taws xob tracing tropical los qhia rau koj.
Nyob rau hauv qhov xwm txheej ib txwm muaj, kev siv cov dej tiv thaiv kab dej kub tsuas yog xav tau kom cov kav dej tsis khov, feem ntau yog li 5 ° C siab tshaj xoom ntawm kab, yog li xaiv qhov kub qis tus kheej txwv hluav taws xob tracing cheeb tsam, nws lub zog 'meter' yog 10W-30W, yog tias qhov kev xaiv tus kheej txwv hluav taws xob tracing cheeb tsam fais fab yog 20W ib 'meter', ces 100 meters ntawm cov kav dej cua sov fais fab yog 2000W. Yog li ntawd, kom paub ntau npaum li cas lub zog hluav taws xob tracing tropical rwb thaiv tsev ntawm cov kav dej hluav taws siv, nws nyob ntawm lub zog 'meter' ntawm cov kav dej cua sov xaiv.
Nov yog kev qhia txog cov sijhawm ib txwm muaj, hauv petrochemical thiab lwm yam kev lag luam, vim yog qhov chaw nyuaj, qhov kub thiab txias siab, qhov kub qis tus kheej txwv qhov kub thiab txias tracing cheeb tsam yuav tsis ua tau raws li qhov yuav tsum tau ua, yog li xaiv qhov kub nruab nrab thiab kub siab tus kheej txwv qhov kub thiab txias tracing cheeb tsam, lub zog hluav taws xob tas li tracing cheeb tsam, lossis MI sheathing cua sov cable thiab lwm yam qauv.
Qhov saum toj no yog kev qhia txog lub zog ntawm 100 meters ntawm cov yeeb nkab dej tiv thaiv kev khov hluav taws xob taug qab thaj chaw sov, thaum lub sijhawm yuav khoom siv hluav taws xob taug qab thaj chaw sov yog tias muaj teeb meem, koj tuaj yeem sab laj nrog peb, cov neeg ua haujlwm tshaj lij tuaj yeem muab cov kev daws teeb meem rau kev lag luam thiab pej xeem ntawm cov kav dej thiab cov khoom siv txij nkawm kub tiv thaiv kev khov hluav taws xob taug qab.
