Armored cable is a special type of cable characterized by having a metal or other material armor layer, which is usually located outside the insulation layer of the cable. It is used to enhance the mechanical protection, corrosion resistance, and extend the service life of the cable. twelve

Armored cables are suitable for various environments, such as chemical engineering, metallurgy, mechanical manufacturing, power generation, and scientific testing. They are used for temperature measurement, signal transmission, special heating, etc. They are widely used in harsh environments because the armor layer can provide additional protection to prevent cable damage. The types of armored cables include armored thermocouples, armored thermal resistors, armored heaters, and armored leads, among which armored thermocouples are the most commonly used type.

1: Introduction

Underground armored Rubber cable are made of different material conductors in metal sleeves with insulating materials, which are processed into flexible solid assemblies. Armored cables include armored thermocouples, armored thermal resistors, armored heaters and armored leads. They are mainly used for temperature measurement, signal transmission and special heating in chemical engineering, metallurgy, mechanical manufacturing, power generation and scientific testing. The largest amount of armored thermocouples is used. Armoured cables are generally fixed power cables. Generally speaking, they are fixed in one place and basically do not move. Power lines transmit electric energy. In addition to the above, the purpose of adding armor layer to the cable can also enhance the tensile strength, compressive strength and other mechanical protection to extend the service life. The armor has a certain resistance to external forces, and can also prevent rats from biting, so as not to cause power transmission problems through the armor. The bending radius of the armor should be large, and the armor layer can be grounded to protect the cable.

2: Product Information

The underground armored rubber cable is designed for use in underground applications. These cables feature a bare copper conductor that is stranded for increased flexibility, and the insulation is made of rubber material. The tinned copper braided screen helps to protect against electromagnetic interference, while the steel wire braided armor provides excellent mechanical protection. The sheath of the cable is also made of rubber, and it is black in color. The cable has a fixed temperature range of -50℃ to +135℃, making it suitable for use in a wide range of environments. The minimum bending radius of these cables is 7.5 times their diameter. These cables have a nominal voltage of 0.6/1KV, making them suitable for use in a variety of electrical systems.

5.Application Scenarios:

Underground armored Rubber cable

These cables are used for electricity supply in low voltage installation system, they are suitable for installation in indoors and

outdoors, in cable ducts, underground, in power and switching stations, local energy distributions, industrial plants

The mechanical protective layer of armored cables can be added to any structure of the cable to increase its mechanical strength and improve its corrosion resistance. It is designed for areas that are prone to mechanical damage and extremely susceptible to erosion. Any method can be used for laying, which is more suitable for direct burial laying in rocky areas.
Armored cables are generally fixed power cables, which are fixed in one place and basically do not move, and power lines transmit electrical energy.

The purpose of adding armor layer to cables is not only to enhance tensile strength, compressive strength and other mechanical protection, but also to extend their service life.
Armor has certain resistance to external forces and can also prevent rodents from biting, so as not to cause power transmission problems through the armor. The bending radius of the armor should be large, and the armor layer can be grounded to protect the cable.
