SatisfactoryElectric tropicsIt is safe in itself and hardly self-propelled. Daily fire incidents are largely the result of irregular installation. Process irregularities, such as wiring, fixation and sealing, can lead to heat accumulation, short circuits, overloading problems and major fire hazards。
There's a fire in the tropics
The overlap of cables is the most common trigger for fire. Much of the work has been done to accommodate the tropical entanglement of stacking and cross-posting. Free temperature with tropical overlap areas is undispersed, heat piles continue to accumulate, temperature rises rapidly, and the insulation layer melts. In long-term heat build, short-circuit fires of wires directly trigger spontaneous combustion of cables. The construction must ensure that the single line is smoothed, that there is no overlap, no cross-cutting, no stacking and that the risk of local fusion is eliminated。
The violent construction has caused hidden damage and has become highly tempting. Forced pull, bending cables, or piercing by a piping, sharp objects, causing hidden damage to the insulation layer. The nuances that are difficult to detect in the naked eye can be followed by localized electricity leaks and short circuits. The continued heat and carbonization of damaged positions in long-term operations, which gradually expand the range of failures and eventually trigger fires, is an extremely hidden security hazard。
Security failure
The irregularity of the fixed mode increases the probability of an ageing route. Part of the construction was carried out using wires, rigid straps and cables, which were too tight and squeezed into transformer line cores and insulation layers. When the piping heats up, cold indentation, the rigid bundling position will continue to wear, cut and break, causing insulation damage. The correct approach is to apply pressure-sensitive tape spacing and the laxity of the piping wall, both to prevent the suspension of the wire and to avoid crowding and damage and to prevent short road fire。
The connection was not sealed up and the leak caused a short-circuit fire. Switchboxes, terminals, intermediate and indirect headers are at high point of failure. Deficiencies in the connection during the construction process, the presence of threads, and insufficient seal fillings could render the waterproof seals ineffective. Rain and snow weather water vapour penetrates inside the interface, causing the core to get wet and leak short circuits. Fire accidents are caused by the continuous heating and carbonization of the water at the dotage, and by highly flammable cable protections and surrounding temperature protection materials。
Power connectors
Virtually all the fires in the tropics of electricity were caused by irregularities in human installation. Strict adherence to wiring standards, the elimination of overlapping, violent construction, the use of pressure-sensitive tape to regulate fixed wires, and the provision of wire seals and temperature protection will completely avert the risk of fire and guarantee the safe and stable operation of the electrical heating system。
