What is the difference between armored cable and non-armored cable?

Classification

Armor is divided into steel tape armor (22, 23), thin steel wire armor (32, 33), thick steel wire armor (42, 43).

Steel cable armored cable models are VV22, VVP22, ZRVV22, NH-VV2;

Control cable steel cable armored cable, models are KVV22, KVVP2, KVVP22, ZR-KVV22,

Steel wire armored power cables and cables, models are VV32, YJV32, ZR-VV32,

Steel wire armored control cable cable model KVV32 KVVP32

Armored communication cable model: HYA53, HYAT53, HYA23, HYV22, HYA22 (rat proof, buried)

The production of foreign armored cables is mainly concentrated in several developed countries, such as the United States, Britain, Japan, Germany, Russia, and there are no manufacturers in Southeast Asia, but as long as there are chemical, metallurgy, machinery manufacturing, power generation and other industries for temperature measurement, armored cables Install the cable.

Use

Armored cable mechanical protection can be added to any structural cable to increase the mechanical strength of the cable and improve corrosion resistance. It is a telephone cable designed for areas prone to mechanical damage and extreme erosion. Can be laid arbitrarily, more suitable for direct burial in rocky areas.

Armored cables are generally fixed laying power cables. Generally, it is fixed in one place, basically immobile, and the power line transmits electrical energy. In addition to the above, the purpose of armoring the cable is to enhance mechanical protection such as tensile strength and compressive strength to extend service life. The armor has a certain resistance to external forces and can also prevent rat bites. It does not cause power transmission issues through armor. The bending radius of the armor should be large, and the armor layer can be grounded to protect the cable.
