What is the difference between copper core cables with armor and without armor?

Armored copper core cable refers to copper core power cable with armor. Generally, armored copper core cable needs to be selected when the cable needs anti-impact protection.

一. The difference between armored and unarmored copper core cables

Armored cable: It is a layer of metal or other material (depending on the environment in which the cable is laid) added to the outer insulation layer of the cable to protect the cable from being damaged by external mechanical force, corroded by chemical gases, etc. This layer is the armor layer.

 

Unarmored cable: Unarmored cables have sheaths or other protective layers, which can also protect the cable insulation, but the mechanical tension and pressure they bear are not as large as armored cables, and they are not unprotected cables.

 

With armor and without armor, you can think of armor as armor. For example, if the cable is directly buried, if it is not armored, it is easy for objects to pierce the sheath and insulation layer, which may cause grounding accidents. The price of armored cables is generally 12-15% higher than that of unarmored cables.

二. Characteristics of armored copper core cable selection

 

1. The mechanical protection layer of armored cable can be added to cables of any structure to increase the mechanical strength of the cable and improve its anti-corrosion ability. It is designed for wires and cables that are susceptible to mechanical damage and extremely susceptible to erosion. It can be laid in any way, and is more suitable for direct burial in rocky areas.

 

2. Armored cables are generally fixed power cables. In layman's terms, they are fixed in one place and basically do not move. The power line transmits electrical energy.

 

3. The cable is added with an armor layer, which can also enhance mechanical protection such as tensile strength and compressive strength to extend its service life.

 

4. The armor has a certain resistance to external forces, and can also prevent rats from biting, so as not to cause power transmission problems through the armor. The bending radius of the armor should be large, and the armor layer can be grounded to protect the cable.

 

三. Scope of application of armored copper core cable

 

Direct buried cables should generally use armored cables, which have strong mechanical strength and protection capabilities.
