​Briefly describe the functions and models of armored cables?

Armored cable is a type of cable designed to meet specific environmental challenges. It adds one or more layers of metal materials, such as steel tape or steel wire, to the cable insulation to provide additional mechanical protection. This design not only enhances the durability of the cable, allowing it to work stably for a long time in harsh environments, but also prevents cable failures caused by animal gnawing or physical damage. Below I will give you an overview of the main functions of armored cables and their common models.

The main function of armored cable

1. Enhanced mechanical strength: The armor layer can significantly improve the cable's ability to resist external mechanical pressure, such as preventing ground load from damaging the cable during direct burial installation.

2. Anti-rodent bite: Some armored cables are designed specifically to prevent rodent bites.

3. Moisture and corrosion resistance: In humid or chemical-rich environments, the armor layer can provide an additional barrier to protect the cable from moisture or corrosive substances.

4. Anti-electromagnetic interference: In some cases, the armor layer can also be used as part of the shielding layer to reduce the impact of electromagnetic interference on signal transmission.

Common models of armored cables

There are many types of armored cables, here are some common types:

1. Power cable

YJV22/YJLV22: Cross-linked polyethylene insulated PVC sheathed steel belt armored power cable, suitable for direct burial, pipe penetration, cable trench and other occasions.

YJV32/YJLV32: Cross-linked polyethylene insulated PVC sheathed steel wire armored power cable, suitable for high drop and high tension.

2. Control cable

KVV22/KVVR22: PVC insulated PVC sheathed steel belt armored control cable, used for fixed control lines.

KVV32/KVVR32: PVC insulated PVC sheathed steel wire armored control cable, suitable for occasions requiring higher mechanical strength.

3. Communication cable

HYA22/HYA53: Polyolefin insulated plastic-coated aluminum belt shielded polyethylene sheathed steel belt armored communication cable, suitable for direct burial and overhead laying.

HYAT22/HYAT53: Polyolefin insulated plastic-coated aluminum tape shielded polyethylene sheathed steel tape armored filled communication cable for moisture and rat resistance.

4. Special purpose cables

VLV22/VV22: PVC insulated PVC sheathed steel tape armored aluminum core/copper core cable for low voltage power distribution systems.

VLV32/VV32: PVC insulated PVC sheathed steel wire armored aluminum core/copper core cable for applications requiring higher mechanical strength and tensile strength.

Notes

When selecting armored cables, it is also necessary to determine the most suitable model based on the specific application environment and technical requirements. For example, for occasions with higher fire protection requirements, armored cables with flame retardant or fire resistant properties can be selected; for applications that require frequent bending or movement, a softer armor structure may need to be selected.
