How to use the cable reel correctly in the
natural environment of industrial production, because of the convenience,
durability and strong function of the cable reel, it has been widely warmly
welcomed. Whether it is in our daily life or in the construction site, it is
widely used. However, many customers still encounter such problems in actual
operation, so what problems should we pay attention to when applying cable
reels?
1. be sure to check whether the power
socket or cable is damaged before application, and carry out inspection
immediately. If you find any damage to the cable, you should immediately ask a
professional and technical personnel with professional knowledge of power
engineering to solve it. Damaged cables are delivered to prevent adverse
effects.
2. When the cable reel moves on the road,
be sure to pay attention to the coiling method and orientation of the cable to
prevent the cable from falling off loosely.
3. When using the cable reel, all cables
must be loosened to prevent the electromagnetic field with high power and
endanger the normal application of the cable reel.
4. Prevent stress. In the whole process of
application of wires and cables, we must pay attention to prevent them from
being pressed by hanging objects. If the cables are pressed by hanging objects,
it is likely to cause a part of the cables to be broken, resulting in high
characteristic impedance, making the cables hot, and the insulation layer.
Surface damage, resulting in cable breakage.
5. Pay attention to the function of the
cable reel. The functions of the cable reel necessary in different natural
environments are different. There are many types of cable reels, the main ones
are explosion-proof type, waterproof and rainproof type, mobile type,
high-power type, etc. It must be selected from many aspects according to the
actual application.
The cable reel is a very labor-saving and
convenient long-distance power energy transmission equipment. Everyone can
obtain various energy materials or special tools in a time-saving and
labor-saving manner. Really save working time and improve work efficiency.
So why are the cable reels made of plastic?
We know that the cable reel is to be used
as a mobile switching power supply and has the function of communicating the
amount of incoming current. This means that the switching power supply must be
connected to the cable reel when it is working, and the current will be
conducted according to the cables bypassing it. Since cable reels are mainly
used in large and medium-sized production and manufacturing office environments
such as power engineering power plants, railway line ships, steel
infrastructure, and building construction, the necessary cable lengths are
relatively long. Once the length of cable required for the job is reduced, the
remaining cable must be spooled to work on the cable reel. This is the
situation that wire rope reels have to deal with.
When the cable is working, it will cause a
certain amount of heat because it has a resistor. When the cable is dissipated
in the work, this heat will be released, which does not constitute any harm.
However, when the cable is coiled on the wire rope reel, the heat released by
thousands of cables gathers together, continues to rise because it cannot be
released, and will be transmitted to the wire rope reel that touches. If the
wire rope reel is made of metal material, the strong heat transfer performance
of metal material and the fact that it is not an insulating layer is very easy
to cause risks, while the plastic is relatively much better. Because the
plastic insulating layer is not easy to endothermic reaction, this this kind of
heat cannot cause all the damage on the plastic wire rope reel.
