Usually power supply cables can be roughly divided into armoured electrical cable and xlpe unarmoured cable. Armoured electrical cable refers to a copper core power cable with an armored sheath. When the power supply cable needs to be laid in some irresistible environments, it is necessary to protect the cable against impact, and the armoured wire for electric cable is a better choice. So what is the difference between armoured electrical cable and xlpe unarmoured cable?
Armoured electrical cable is to add a layer of metal or other substances on the outer insulation layer of the cable to protect the cable from damage by external mechanical force, chemical gas corrosion, etc. according to the environment in which the cable is laid. Layers are metal armor layers or other substances. The sheath layer of the xlpe unarmoured cable will be one less layer, but the nature of the cross-linked PE 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.
DIVERSE PROPERTIES
Armoured power supply 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 electrical cable manufacturer can design the bending degree of the armored cable to be so large, so the performance of the armoured electrical cable is better than that of the xlpe unarmoured cable.
APPLICATION RANGE
The armored electrical cable laying method generally adopts the direct burial method, because the armoured wire for electric 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. Armoured cables are 12-15% more expensive than xlpe unarmoured 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.
Although copper electrical wire is very popular because of its excellent electrical conductivity, the price of copper metal has been rising in recent years, and aluminum electrical wires and cables has become more and more popular with many engineers and buyers in recent years. Such as more and more building speciality contractors like to purchase aluminum aerial bundled cable0.6/1kv, additionally the X-90 insulation.
