So Many Kinds Of Cables Here!

Published by Author: Joey Wan August 23,2022

As we all know, we live in a time full of light. We have survived the ancient days of burning fire for light.

Now we have cables in our lives, cables that can be powered and can bring us light. We must make good use of the convenience that cables bring to our lives and do more things we want to do.

Now let's take a look at the structure of the cable!

1. What is the function of the outer sheath of the cable?

Answer: Protect the inner sheath from mechanical damage and chemical corrosion, and enhance mechanical strength.

2. What requirements should the outdoor cable trench meet?

Answer: The upper part of the cable trench should be slightly higher than the ground, covered with a cover made of concrete, the cable should be laid flat on the bracket, and there should be a good drainage pipe.

3. What is the function of the inner sheath of the cable?

A; The insulating layer will not come into contact with water, air or other objects, to prevent the insulation from being damp and the insulating layer from mechanical damage.

4. What should be paid attention to when using wire cutters?

Answer: Before use, be sure to check whether the insulation of the insulating handle is in good condition. Do not use wire cutters to cut metal wires that exceed the allowable specifications, and it is forbidden to use wire cutters instead of hammers to hit the tool to avoid damage.

5. What is dielectric strength?(Solar  cable )

Answer: Insulating substances in the electric field will be broken down when the electric field strength increases to a certain limit. The electric field strength that causes insulation breakdown is called dielectric strength.
