Abanye abantu babuza ukuba i-self-limiting heat cable yi-parallel heat cable, i-voltage yecandelo lokuqala nelokugqibela kufuneka ilingane, kwaye ukushisa kwecandelo ngalinye kufuneka kulingane. Kwenzeka njani ukuba kubekho ubushushu obuphantsi bokufudumeza ekugqibeleni? Oku kufuneka kuhlalutywe ukusuka kumgaqo womahluko wombane kunye nomgaqo wokushisa okuzibekela umda.

Yintoni umahluko wombane? Xa i-current idlula kwi-cable yokufudumala yombane, kuya kuba nokwahlukana kombane phakathi kweziphelo zayo ezimbini. Umsebenzi we-voltage kukunceda okwangoku ukudlula ukuchasana kakuhle kwaye wenze i-loop. Okukhona ukuxhathisa okukhulu, kokukhona utshintsho olukhulu kumahluko wombane.

I-self-limiting temperature heat cable ngokwayo ineempawu zokutshintsha kunye nokutshintsha kobushushu be-ambient. Ubushushu obuphezulu be-ambient buya kwandisa ukuchasana kunye nokunciphisa ukudlula okwangoku. Iqondo lobushushu ekupheleni komsila liphantsi, nto leyo enokuba ngenxa yokuba ukuxhathisa kuba mkhulu, umsinga odlulayo uba mncinci, kwaye umahluko wombane phakathi kwentloko nomsila uphela uba mkhulu, nto leyo eqhelekileyo.

Esinye isizathu kukuba ubude be-self-limiting ikhebula lokufudumeza ubushushu ngokwayo bugqithiswa ngexesha lofakelo. Ngenxa yokuba i-self-limiting temperatures yokumelana nokufudumala kombane iya kutshintsha kunye nobushushu, ukuphakama kokumelana ekupheleni kwentambo yokufudumeza, iqondo lokushisa lisezantsi. Ukuze ugweme le meko, ubude obuthile bekhebula lokufudumeza kombane kufuneka lugcinwe ngexesha lofakelo.
