Why you need the armored electrical cable

What is the armored electrical cable?

Armored electrical cable refers to a cable with a metal armored protective layer. The purpose of the armored layer is not only to increase the mechanical protection and elongation service life such as tensile strength and compressive strength but also to improve the cable’s anti-interference performance through shielding protection.

Types of armored electrical cable

The armored electrical cable usually has some armored layer beneath the outer jacket to protect the integrity and electrical performance of the cable structure and increase the service life.There are usually two types of armor, steel tape armor, and steel wire armor.

In order to bear the radial pressure of the cable, a double steel belt and gap winding process is adopted, which is called steel belt armored electrical cable. After cabling, the steel belt is wrapped around the cable core, and the outer jacket is extruded.

This type of armored electrical cable is generally used in where has a large load pressure. For example crossing roads, squares, and roads, railroads, etc., It also used in where has large vibrations, and are suitable for laying underground, tunnels, and pipes.

In order to withstand large axial pull forces, multiple low carbon steel wire wrapping processes are used, known as steel wire armored cables. After cabling, the steel wire is wrapped around the core wire at the necessary pitch and then squeezed. This type of cable is generally used where the span and gap are relatively large.

When you need the armored electrical cable

The armored protection layer can be added to any type of the cable to increase the mechanical strength and improve the corrosion resistance. It is a special cable designed for areas that are susceptible to mechanical damage and corrosion. It can be laid in any way and is more suitable for direct laying in rock areas.

The purpose of the power transmission electrical cable to install the armor layer is to increase the tensile strength, compressive strength, and other mechanical protection and elongation service life, and the armored device must have the necessary resistance to external forces. It can also prevent rats from biting, so as not to cause power transmission problems through armor. The bending radius of armor is larger, and the armor layer can be grounded to protect the cable.
