Why is there white powder inside the power cable?

1 year ago | articles

Today, electrical energy and electricity flow have affected a large part of our human lives. From home lighting 
and heating to running industries and medical equipment, our dependence on this vital resource is increasing day
 by day. Behind this invisible current, there is a complex network of electric cables that are responsible 
for the transmission of electricity. At first glance, these cables may look like simple wires hidden underground 
or on power poles. But deep within these wires lies a wonderful world of components that are essential to
 the safe and efficient operation of our electrical systems.

In this article, we will take a trip inside the power cable and explore one of its key components,
 the white powder. This fine material, which is often magnesium oxide or talc, plays an essential
 role in improving the performance of the cable and brings several benefits. In the rest of this
 article, we will take a closer look at this powder and its role in electric cables. Stay with us.



Why is white powder used in electric cables?

As mentioned in the previous section, white powder is one of the key components of the electric cable that 
plays an essential role in its safe and efficient operation. In the following, we will take a closer
 look at the reasons for using powder in electric cables.

Fire and explosion prevention:
One of the most important tasks of white powder in electric cable is to prevent fire and explosion.
 As a result of short circuit or overload, a lot of heat is generated in the cable, which can lead to
 melting of the insulation and sparking. By absorbing heat and moisture, white powder prevents
 cable temperature from rising and causing fire.



Cable protection against corrosion:

Electric cables are exposed to various factors such as moisture, chemicals and soil, which can cause corrosion of the
 conductor and insulation wires. Corrosion not only damages the performance of the cable, but can lead to leakage
 of electric current and serious hazards to people. By creating a physical barrier between the wires and the
 insulation, the powder protects them from corrosion.

Improved cable flexibility:
Cable flexibility is one of the important factors that must be considered when installing
 and working with electric cables. Flexible cables are easily bent and can be installed in limited spaces. 
By reducing the friction between the wires and the insulation, the white powder increases the flexibility 
of the cable and makes it easier to work with.

4. Reducing electrical interference:
Electrical interference is a phenomenon caused by the passage of electric current through cables and can
 negatively affect the performance of other electrical and electronic equipment. By absorbing electromagnetic
 waves, white powder reduces electrical interference between cables and helps maintain a clear and noise-free signal.

Fill in the blanks:
In some cables, white powder is used to fill the voids between the wires and the insulation. 
This helps to stabilize the wires in place and prevent them from moving due to vibration or impact.
