Meta tuża kejbils ta 'tisħin elettriċi fuq tagħmir tal-pipeline, kif tagħżel il-mudell tal-prodott korrett huwa wieħed mill-fatturi importanti għall-effett ta' insulazzjoni termali, minħabba li mhux biss jista 'jiffranka l-flus, iżda jista' wkoll ikollu l-aħjar effett skond mudelli differenti. Fl-għażla attwali, diversi fatturi jeħtieġ li jiġu kkunsidrati b'mod komprensiv, bħal: sikurezza, adattabilità, kontroll tal-ispejjeż, konsum tal-enerġija, eċċ., U jekk hemmx korrużjoni serja jew le.
Fost dawn, it-temperatura hija fattur importanti fl-għażla tat-tip ta 'kejbil tat-tisħin elettriku, għalhekk meta t-temperatura tissodisfa r-rekwiżiti, it-temperatura għolja miksuba b'operazzjoni aċċidentali għandha titqies ukoll:
1. The electric heating cable whose working temperature is higher than the maintenance temperature of the pipeline by a certain range should be selected, so as to ensure that the electric heating cable has enough power in the designed working temperature area, which can compensate the heat loss of the system.
2. Determine whether there will be occasional temperature rise in the pipeline, such as steam, hot water, hot oil cleaning and other pipelines, so the temperature of the selected electric heating cable should not be lower than the occasional temperature rise.
3. If the occasional temperature rise of the pipeline is higher than the withstand temperature of the electric heating cable, the installation method can be adjusted after thermal estimation, and a suitable layer can be added between the electric heating cable and the pipeline. Insulation layer to alleviate the impact of occasional temperature rise on the electric heating cable.
L-utent jista 'ma jkunx ċar ħafna dwar l-għażla tal-mudell tal-kejbil tat-tisħin elettriku. F'dan iż-żmien, it-tekniċi tal-manifattur jistgħu jgħinu biex jagħżlu, u l-utent jeħtieġ li jipprovdi lit-tekniċi tal-manifattur bil-parametri dettaljati tat-tagħmir iżolat, sabiex it-tekniċi tat-tisħin elettriku jkunu jistgħu jagħżlu għall-utent. Mudell xieraq tal-kejbil tat-tisħin elettriku biex tiġi evitata l-influwenza tal-effett ta 'insulazzjoni termali minħabba għażla mhux xierqa tal-mudell.
