Armored cable

Armoured cables 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.

Classification of armored cables

Armor is divided into steel strip armor (22, 23), thin steel wire armor (32, 33), and thick steel wire armor (42, 43). The models of steel strip armored cables include VV22, VVP22, ZRVV22 and NH-VV2. Control cable, steel strip armored cable, models are KVV22, KVVP2, KVVP22, ZR-KVV22. Steel wire armored power cable with models of VV32, YJV32 and ZR-VV32. The model of steel wire armored control cable is KVV32 KVVP32. Armored communication cable models: HYA53, HYAT53, HYA23, HYV22, HYA22 (rat proof, buried). The production of armored cables abroad is mainly concentrated in several relatively developed countries, such as the United States, Britain, Japan, Germany, Russia, and there is no manufacturer in Southeast Asia. However, as long as there are chemical, metallurgical, mechanical manufacturing, power generation and other industries, there is temperature measurement, so armored cables are needed.

Purpose of armored cable

The mechanical protective layer of armored cable can be added to the cable of any structure to increase the mechanical strength of the cable and improve the corrosion resistance. It is designed for the area vulnerable to mechanical damage and extremely vulnerable to corrosion. It can be laid in any way, which is more suitable for direct buried laying in rock areas. 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 cables can also enhance 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.

Advantages of armored cable

1. The protective layer of armored cable machinery can be used on any structure of cable. It can enhance the mechanical strength of the cable and play a role in corrosion prevention. It can avoid mechanical damage or corrosion, so as to design the wire and cable. It can be laid in many ways, and the armored cable of steel strip is laid flat and straight, which will bear an external force in the horizontal direction. 2. After adding armor on the cable, its tensile strength can be enhanced, and the strength will also be improved, so that the use time of the machine will be enhanced. Moreover, the armored cable has excellent resistance to external forces, which can prevent insects and ants from biting.
