Armored cable refers to a copper core power cable with an armored sheath. In the environment we live in, there are various environments. When the cable needs to be laid in some irresistible environments, it is necessary to protect the cable against impact, and the armored copper core cable is selected. So what is the difference between armored copper core cable and unarmored cable?
1. Different structure
Armored cable is to add a layer of metal or other substances on the outer insulation layer of the cable to protect the cable from external mechanical force damage, chemical gas corrosion, etc. According to the environment in which the cable is laid. The surface layer is a metal armor layer or other substance. The sheath layer of the unarmored cable will be one less layer, but the nature of the XLPE alone can protect the cable, but the mechanical force and pressure it bears are not as large as the armored cable.
The armored cable structure has an unusual mechanical protection layer, which can increase the mechanical strength of the cable and improve the corrosion resistance. It is a wire and cable designed for areas prone to mechanical damage and high corrosion; it can be laid in any way, and is more suitable for direct burial in stony areas.
Armored cables have enhanced protective properties such as ductile strength and compressive hardness for extended service life. The armored protective layer has a certain resistance to external forces, and can also prevent mice from biting, so that the armored cable will not cause power transmission problems. The bending radius of the armored cable is relatively large, because the armored layer can better protect the cable. Therefore, the cable manufacturer can design the bending degree of the armored cable to be so large, so the performance of the armored cable is better than that of the non-armored cable.
The armored cable laying method generally adopts the direct burial method, because the armored cable has strong mechanical strength and protection ability, the cable is directly buried, if it is not armored, it is easy to be pierced by other hard objects. Causes direct cable damage, power leakage, short-circuit fire and other problems. Armored cables are 12-15% more expensive than non-armored cables on the market.
The cable has an armored protective sheath, which can be used in any outdoor environment without fear. Whether it is laid in a stone environment or buried directly in the soil, it can be easily dealt with, and it is not afraid of animal bites. It really provides engineers with Unparalleled convenience and safety of use.
