Armored cable refers to the copper core power cable with an armored sheath. 

In our living environment, there are a variety of environments, when the cable needs to be laid in some irresistible environment when the cable needs to be protected against impact, we need to choose a special outdoor armored cable.

What is the Outdoor Armored Cable?

Outdoor armored cables generally consist of loose tubes made of color-coated fibers and filled with a waterproof compound.

Strength components, such as aramid yarns or glass yarns, are uniformly wrapped around the outside of the loose tube.

Features of Outdoor Armored Cables

1 Outdoor armored cable mechanical protection layer can be added to any structure to increase the mechanical strength of the cable. 

It also improves erosion resistance and is a wire and cable designed for areas prone to mechanical damage and highly susceptible to erosion. The cable can be laid in any way, due to its outdoor characteristics, more suitable for direct burial in rocky areas.

2 Outdoor armored copper core cable is generally fixed laying power cables, in common parlance, is fixed in one place basically can not be moved, the power line transmits electrical energy.

3 Cables plus an armored layer can also enhance the tensile strength, compressive strength, and other mechanical protection to extend the service life.

4 Armored with a certain degree of resistance to external forces, but also to prevent rats from biting, not to cause power transmission problems through the armor.

The bending radius of the armor should be large, the armor layer can be grounded to protect the cable.

5 About the cable armor layer, can be seen as the cable conductor armor.

For example, if the cable is buried directly, if it is not armored, it is easy to be pierced by sharp objects in the sheath and insulation, which may cause grounding accidents.

Outdoor Armored Cable Types

Steel ribbon armored cable models are VV22, VVP22, ZRVV22, and NH-VV2.

Control cable steel belt armored cable models are KVV22, KVVP2, KVVP22, and ZR-KVV22.

Steel wire armored power cable models are VV32, YJV32, and ZR-VV32.

Steel wire armored control cable cable models: KVV32, KVVP32.

Mounted communication cable models: HYA53, HYAT53, HYA23, HYV22, HYA22 (anti-rodent, buried).

So what is the difference between outdoor armored copper core cables and cables without armor?

1 Cable Structure is Different

Armored cable is in the outer insulation layer of the cable to add a layer of metal or other substances, according to the environment in which the cable is laid to protect the cable from external mechanical force damage, chemical gas corrosion, etc., the layer is a metal armor layer or other substances. 

Non pinned cable sheath layer will be less than one layer, but the nature of the crosslinked pe alone can also protect the cable, but it is subjected to mechanical force and pressure is not as big as the armored cable.

2 Non-Armored Cable Performance is Different

An armored cable structure with a layer of the non-general mechanical protection layer, can increase the mechanical strength of the cable, and improve corrosion resistance. It is a wire and cable, designed for easy mechanical damage and extremely corrosive areas and design; can take any way of laying, more suitable for stone areas of direct burial laying.

Armored cables have stronger protective properties, such as toughness strength and compression hardness, to extend service life. 

The armored protective layer has a certain resistance to external forces and also prevents mice from chewing, which will not make the armored cable cause power transmission problems. 

The bending radius of the armored cable is larger because the armored layer can protect the cable better, therefore, the cable manufacturer can design the bending degree of the armored cable so big, that the performance of the armored cable is better than the non-armored cable.

3 Cable Scope of Application

The armored cable laying method is generally used in the way of direct burial because the armored cable has strong mechanical strength and protection ability, the cable is buried directly, if not armored, it is easy to be pierced by other hard objects sheath, and insulation, resulting in direct damage to the cable, power leakage, short-circuit fire and other problems. In the market, armored cable is 12-15% higher than the price of non-armored cable.

When the cable has an armored protective sheath, it can be used outdoors in any environment without fear.

Whether laid in a stony environment or buried directly under the soil outdoor cables can easily cope with it.

Can also be fearless of animal bites, really to the engineers and users to provide a great convenience and the use of security.
