What Are the Main Uses of Frls Armored Cables?

Introduction to Frls Armoured Cables

Frls armoured cables refer to cables with a metal armor protection layer. The purpose of adding an armor layer to the cables is to enhance mechanical protection such as tensile strength and compressive strength, and extend the service life. Frls armoured cables include armored thermocouples, armored thermal resistors, armored heaters, and armored lead wires, which are mainly used for temperature measurement, signal transmission, and special heating in chemical, metallurgical, mechanical manufacturing, power generation, and scientific experiments, etc.

Frls armoured cables are generally fixed laying power cables, which are permanently fixed in one place and will not be moved to another place. The mechanical protective layer of frls armoured cables can be added to cables of any structure to increase the mechanical strength of the cables and improve their corrosion resistance. They are wires and cables designed for areas prone to mechanical damage and corrosion. They can be laid in any manner and are more suitable for direct burial in rocky areas.

The Differences between Frls Armoured Cables and Ordinary Cables

Armoring refers to the outer protective layer of the cable wrapped with steel strips or steel wires to protect the cable from external mechanical forces; cross-linked cables refer to the insulation layer outside the cable conductor made of cross-linked polyethylene. Armored cross-linked polyethylene cables can be used, which are cables insulated by cross-linking materials and protected by an outer armor layer.

Armor has a certain resistance to external forces and can also prevent rodent bites to avoid power transmission problems caused by armor. The bending radius of armor should be large, and the armor layer can be grounded to protect the cable.

Commonly used armor materials include steel strips, steel wires, aluminum strips, aluminum tubes, etc. Among them, steel strip and steel wire armor layers have high permeability and good magnetic shielding effect, which can be used to resist low-frequency interference. Armour plated cables can be directly buried without the need for conduits, making them cost-effective in practical applications.

The code for armour plated cables represents adding a number on ordinary cables, with "2" representing double steel strip armor; another "2" representing PVC sheath, for example, replacing "2" with "3" for polyethylene sheath. For example, YJV represents ordinary cables, and YJV22 represents armour plated cables.

The price of armored cables with armor is generally 12%-15% higher than that of non-armored cables.

Cables already have good external protection, such as protection with threaded steel tubes or laying in areas with good operating environments. From an engineering economic perspective, ordinary cables can be used without armor.
