Ada banyak alasan untuk kebakaran sistem pemanas listrik, yang paling penting adalah pemasangan kabel pemanas listrik. Setiap orang harus mengetahui metode pemasangan konvensional, dan telah melihat banyak di-kasus pemasangan di situs atau gambar kasing online. Berikut ini adalah analisa singkat poin-poin penting pemasangan kabel pemanas listrik yang akan menyebabkan kebakaran.
Penyebab kebakaran di ujung kabel pemanas listrik:
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.
Kotak persimpangan akan menyebabkan sirkuit di-ground. Ketika kontak perlindungan pembumian tidak baik, mudah menimbulkan percikan listrik dan menyebabkan kebakaran.
Penyebab kebakaran di tengah kabel pemanas listrik:
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.
Singkatnya, ini adalah beberapa alasan kebakaran kabel pemanas listrik di sistem pemanas listrik. Demi keamanan, harap pasang dan gunakan kabel pemanas listrik dengan benar.
