Cable jacket and also insulation as layers are often made of plastic-type and rubber components with flammability. If the cable overload, quick circuit, overheating as well as other fault conditions and also external thermal insulating material materials under insulating material resistance will cause decline, loss regarding insulation, and also burning, triggering any fire. Therefore, the laying with the cable-intensive place, can simply cause fires. Additionally, once the hearth, the fire can burn down the extension with the cable and distributed, causing significant monetary losses.
