Armored cables are made of conductors of different materials in insulated metal bushings, which are machined into a flexible solid assembly. Armored cables are generally fixed laying power cables, which are generally fixed in one place and basically do not move, and the power line transmits electrical energy. Armoured cable includes armoured thermocouple, armoured thermal resistance, armoured heater and armoured lead, mainly used in chemical industry, metallurgy, machinery manufacturing, power generation and scientific test temperature measurement, signal transmission and special heating, the largest amount is armoured thermocouple.

Armored cable classification

Armouring is divided into steel band armouring (22,23), fine steel wire armouring (32,33), thick steel wire armouring (42,43).

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

Control cable steel tape armored cable, model KVV22, KVVP2, KVVP22, ZR-KVV22

Steel wire armored power cable cable, model VV32, YJV32, ZR-VV32

Wire armored control cable Cable models are KVV32 KVVP32

Armored communication cable models: HYA53, HYAT53, HYA23, HYV22, HYA22(rodent-proof, buried)

Armored cable model meaning

In order to make the cable can withstand the radial pressure, double steel tape, gap wrapping process is adopted, which is called steel tape armored cable; After the cable is formed, the steel tape is wrapped around the cable core, and then the plastic sheath is extruded.

The representation of this cable type is such as control cable KVV22, plastic force cable VV22, communication cable SYV22, etc. The two Arabic digits in the subscript of the cable model, the first one: "2" indicates double steel tape armouring; Second: "2" means polyvinyl chloride sheath, such as using polyethylene sheath to change "2" to "3" can be.

This type of cable is generally mainly used in the occasion of carrying relatively large pressure. For example: through the road, square and vibration relatively large road side, railway side, etc., suitable for buried, tunnel and pipe laying.

In order to allow the cable to withstand the larger axial tension, take a number of low carbon steel wire wrapping process, called wire armored cable. After the cable is formed, the steel wire is wrapped on the core wire according to the necessary pitch and then the sheath is squeezed. The expression method in this cable model is such as control cable KVV32, plastic force cable VV32, coaxial cable HOL33 and so on.

Two Arabic numbers in the model, the first one: "3" indicates fine steel wire armor; Second: "2" means polyvinyl chloride sheath, "3" means polyethylene sheath. This type of cable is generally used in the occasion of relatively large span and large laying drop.

Armored cable uses

Armored cable mechanical protective layer can be added to any structure of the cable to increase the mechanical strength of the cable, improve the erosion resistance, is a telephone cable designed for areas vulnerable to mechanical damage and extremely vulnerable to erosion. It can be laid in any way, and is more suitable for direct buried laying in rocky areas.

Armored cables are generally fixed laying power cables, which are generally fixed in one place and basically do not move, and the power line transmits electrical energy.

In addition to the above, the purpose of the cable with armor layer can also enhance the tensile strength, compressive strength and other mechanical protection to extend the service life.

Armored has a certain external force performance, but also beware of rats biting, not through the armor caused power transmission problems, the bending radius of the armor to be large, armored layer can be grounded, protect the cable.

Foreign armored cable production is mainly concentrated in several more developed countries, such as the United States, the United Kingdom, Japan, Germany, Russia, Southeast Asia has no manufacturers, but as long as there are chemical, metallurgy, machinery manufacturing, power generation and other industries where there is temperature measurement, you need armored cables.

The role of armored cables

Armored cable refers to the cable with metal material armored protective layer, the purpose of the cable with armored layer in addition to enhance the tensile strength, compressive strength and other mechanical protection to extend the service life, but also through shielding protection to improve the anti-interference performance of the cable.

Commonly used armored materials are steel tape, steel wire, aluminum tape, aluminum tube, etc., of which steel tape, steel wire armor layer has high magnetic permeability, has a good magnetic shielding effect, can be used to resist low-frequency interference, and can make armored cable directly buried and free from the pipe, and inexpensive, in the actual application of more.

Armored cable mechanical protective layer can be added to any structure of the cable to increase the mechanical strength of the cable, improve the anti-erosion ability, is a special cable designed for areas vulnerable to mechanical damage and erosion. For example, the cross-linked polyethylene insulated steel tape armoured polyethylene sheathed power cable of the Pearl River cable, the excellent electrical performance of the original cross-linked polyethylene cable coupled with armor, so that it can be laid in any way, suitable for indoor, tunnel, cable trench and underground directly buried laying (buried depth: ≥0.7m from the ground), the cable can withstand a certain mechanical external force.

The purpose of the power line transmission power cable with armored layer in addition to enhancing the tensile strength, compressive strength and other mechanical protection elongation life, but also to prevent some mice from biting, not through the armor caused power transmission problems, armor bending radius to be large, armored layer can be grounded to protect the cable.
