Armored Power Cable

Mechanical damage is one of the leading causes of power cable failure in industrial environments. Underground installation, construction machinery, heavy vehicle traffic, and rodent attacks can easily damage conventional cables, leading to costly downtime.

Armored Power Cable adds a galvanized steel tape armor between the insulation and outer sheath to provide additional protection against external mechanical forces while maintaining stable electrical performance.

Cable Structure

Armored power cables consist of multiple protective layers designed to ensure electrical safety and mechanical durability.

1. Copper or Aluminum Conductor

The conductor has good conductivity and low resistance, providing stable current transmission.
Optional conductors: Copper conductor, Aluminum conductor

2. Insulation Layer

The insulation layer protects the conductor from leakage current and ensures safe operation under various temperature conditions.
Common materials: Cross-linked polyethylene (XLPE) insulation layer, Polyvinyl chloride (PVC) insulation layer

3. Inner Protective Layer

The inner liner provides support between the insulation layer and the armor layer, improving structural stability.

4. Steel Armor Layer

Galvanized steel armor is a critical protective component.
It resists: mechanical shock, compression, external pressure, rodent damage, installation stress.
Optional armor types: Steel tape armor, Steel wire armor

5. Outer Sheath

The outer sheath protects the cable from moisture, corrosion, UV radiation, and environmental aging.
Optional sheath materials: PVC, PE, LSZH

FAQ

1. What is Armored Power Cable used for?

Armored Power Cable is mainly used for underground, outdoor and industrial applications where cables require additional mechanical protection against impact, crushing and environmental damage.

2. What is the difference between armored and normal power cable?

Normal power cables mainly provide electrical insulation, while armored cables add a metal protective layer to improve mechanical strength and durability.

3. Can armored cables be directly buried underground?

Yes. Armored cables are commonly used for direct burial installation because the armor layer provides additional protection against soil pressure and external impact.

4. Steel tape armor or steel wire armor, which is better?

Steel tape armor is commonly used for buried applications requiring mechanical protection. Steel wire armor is preferred for applications involving higher mechanical stress and pulling forces.
