Armoured Cable: A Solid Support for Power Transmission

An armoured cable is a special type of cable characterized by a layer or layers of armor made of metal or other materials wrapped around the outside of the cable. An armoured cable consists of conductors made of different materials housed in a metal sheath with insulation material, processed into a flexible and solid combined body.

Composition of Armoured Cables

Core

The main part responsible for transmitting current or signals.

Insulation Layer

Wrapped around the core to prevent current or signal leakage, while protecting the core from external environmental influences.

Shielding Layer

An optional part used to reduce electromagnetic interference and improve signal transmission quality.

Outer Sheath

Wrapped around the insulation or shielding layer, providing extra mechanical protection and defense.

Armor Layer

The outermost layer made of metal or other hard materials, providing high-strength mechanical protection to prevent the cable from external physical damage.

Types of Armoured Cables

Steel Tape Armoured Cable

Uses steel tape as the armor layer, offering high compressive and tensile strength.

Fine Steel Armoured Cable

Uses fine steel wire woven into a mesh as the armor layer, offering high flexibility and wear resistance.

Thick Steel Armoured Cable

Uses thick steel wire as the armor layer, providing stronger mechanical protection.

Applications of Armoured Cables

Underground Power Transmission

Armoured cables have great application prospects in underground power transmission systems. The complex underground environment poses potential risks such as car pressure subsidence, rodent gnawing, and sharp stone scratches. The mechanical protection layer of armoured cables can effectively prevent these damages and increase the cable's service life.

Environments Prone to Mechanical Damage or Erosion

In areas prone to mechanical damage and erosion, such as rocky areas, mines, and underground facilities.

High Protection Requirement Situations

In industries such as petroleum, chemical, and metallurgy, equipment and facilities often need to withstand extreme conditions like high temperatures and pressures. Armoured cables can provide effective protection for these scenarios, ensuring the reliability of power supply.

Outdoor Facilities

For outdoor facilities such as street lighting and traffic signals, armoured cables can resist vehicle pressure and harsh environmental impacts, ensuring stable and durable power transmission.

Special Heating and Temperature Measurement

Armoured cables also include armored thermocouples, armored thermal resistors, and other types. These cables are used in fields such as chemical, metallurgy, machinery manufacturing, power generation, and scientific experiments for temperature measurement, signal transmission, and special heating.

Highly Reliable Power Supply Requirements

For places using first-class loads, such as in aerospace and national defense technology fields, equipment and facilities require highly reliable power supplies. Armoured cables can provide safe and stable power transmission to ensure the normal operation of equipment.
