Tá go leor cúiseanna ann le tine an chórais téimh leictreach, agus is é an ceann is tábhachtaí ná an cábla téimh leictreach a shuiteáil. Ba cheart go mbeadh an gnáthmhodh suiteála ar eolas ag gach duine, agus go leor cásanna suiteála suímh nó pictiúir de chásanna ar líne feicthe acu. Seo a leanas anailís ghearr ar na príomhphointí a bhaineann le suiteáil cáblaí téimh leictreacha a chuirfidh tinte faoi deara.
Causes of fire at the end of the electric heating cable:
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. It is strictly forbidden to connect the shielding layer of the electric cable to the terminal junction box. In the state of poor contact, it is easy to generate electric sparks and cause fire.
Causes of fire in the middle of the electric heating cable:
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.
To sum up, these are some of the reasons for the fire of the electric heating cable in the electric heating system. For the sake of safety, please install and use the electric heating cable correctly.
