Wires and cables are things that gradually age during use, and when they age to a certain extent, they are very likely to cause fires. In addition to large fires caused by wires and cables, power leakage is also extremely dangerous. Therefore, in addition to ensuring daily inspection and maintenance of wires and cables, it is necessary to know how to deal with unexpected fires in case of wires and cables. Of course, if necessary, you can choose fire-resistant and fire-resistant cables produced by Shenghua Cable, which can reduce the losses caused by fires.

Now let's talk about several common causes of wire and cable fires:

The reason why wires and cables catch fire is because the legal temperature of the wires and cables exceeds their maximum allowable value. So, what are the reasons that can cause wires and cables to heat up?

1. The cable conductor resistance does not meet the usage requirements, resulting in abnormal heating during operation

2. The selected cable model is not suitable, the conductor cross-section of the cable is too narrow, and it is in an overload state for a long time during use, which leads to the inability to maintain a good balance between the heating and cooling of the cable, resulting in cable combustion and fire.

3. The installation of cables did not consider reserving space, resulting in a large number of cables piling up together, causing abnormal heat dissipation, or choosing to install cables too close to other heat sources, resulting in the cables being in a high temperature state for a long time.

4. Technical issues with the operators resulted in excessive resistance at the cable joints, leading to severe heating issues at the joints

The terrifying thing about wires and cables catching fire is that they may also be accompanied by electrical leakage. When dealing with such fires, special attention should be paid to safety. The first thing to do when discovering a fire is to cut off all power sources, and then put up warning lines or signs around the fire to quickly evacuate the surrounding people.

Secondly, the most important thing in a fire is to find the source of the fire. Generally, cable and wire fires are caused by flammable materials in the surrounding area. Simple electrical and cable leaks will only emit sparks. Therefore, once a fire source is discovered, in addition to extinguishing it as soon as possible, flammable materials should also be transferred as soon as possible to avoid secondary fires

Another important point is to focus on analyzing the causes of wire and cable fires, which may be due to mismatched specifications or severe aging. Identifying these reasons can prevent recurrence in the future.

So when purchasing cables, it is necessary to choose qualified products. For example, Shenghua Cable is a cable product that meets national standards through strict production requirements and testing. In order to avoid greater losses, Shenghua Cable also produces special fire-resistant and fire-resistant cables for customers to choose from.

Shenghua Cable Group mainly produces high and low voltage cross-linked cables, power cables (YJV, YJV22, YJLV), distribution wires (BV, BVR, RVV, RVS), aluminum alloy cables (YJLHV), overhead cables, flame-retardant and fire-resistant cables, rubber sheathed cables, control cables (KVV), special cables, and other products.
