Mnogo je razloga za požar sustava električnog grijanja, od kojih je najvažniji ugradnja električnog grijaćeg kabela. Svatko bi trebao poznavati uobičajenu metodu instalacije i vidio mnoge-kolučiće za instalaciju na licu mjesta ili slike kućišta na mreži. Slijedi kratka analiza ključnih točaka ugradnje električnih grijaćih kabela koji će uzrokovati požare.
Uzroci požara na kraju električnog grijaćeg kabela:
1. The end treatment is necessary. Of course, the junction box must also be installed to prevent the end from being damp, which may easily cause short circuit and fire.
2. Improper handling of the tail end exposes the conductive part of the metal. In winter, there is rain and snow, which will cause leakage and fire.
3. The wrapped tape should be waterproof. If the quality is not good, the end will be wet, causing leakage and fire.
4. When installing the terminal junction box, the outer sheath should be stripped off, and the shielding layer should be peeled off.
Razvodna kutija će uzrokovati uzemljenje kruga. Kada zaštitni kontakt uzemljenja nije dobar, lako je generirati električne iskre i izazvati požar.
Uzroci požara u sredini električnog grijaćeg kabela:
1. During the installation process of the electric heating cable, there is no finished product protection for the electric heating cable. Stepping on, dragging, pulling, and twisting the electric heating cable will cause deformation and damage to the inner core of the electric heating cable. Generally, the construction site is relatively messy, even if it is tough The fluoroplastic jacket type heating tape can also be easily cut without attention. Under the condition of long-term high-power and high-temperature operation, the damaged core has uneven heating, and the local temperature is too high, causing fire.
2. The thermal insulation layer has not been waterproofed. In rainy and snowy weather, the thermal insulation layer is infiltrated with water, which makes some lines of the heating cable in a low temperature or humid state and work with a large output power. Excessive current causes internal fire and short circuit, resulting in electric sparks.
3. The outer sheath of the electric heating belt is damaged, and the charged wire core leaks out, and the wire core causes a short circuit in a humid environment in rainy and snowy weather.
Ukratko, ovo su neki od razloga požara električnog grijaćeg kabela u sustavu električnog grijanja. Radi sigurnosti, molimo Vas da pravilno instalirate i koristite električni grijaći kabel.
