Armoured Cable Failure causes

Failure causes

1. When the cable is wired, the cable middle-terminal wiring process does not meet the quality requirements, must comply with the requirements of the cable wiring process, in particular, pay attention to deal with the insulation of the middle-terminal, do not allow moisture to enter the key connections, to avoid affecting its insulation.


2. cable armour steel belt cracks, laps are not good, lead package cracks into the moisture, especially in the cable in the end of the wiring weak links, so that the insulation damage caused by a short circuit, it should be noted that the bending radius of the cable can not be too small, it should be not less than 20 times the outer diameter of the cable.


The good and bad of the wire and cable directly affects the operation of the line safety, once the line can not be safe and stable operation, its failure caused by life and economic losses can not be predicted, so we power staff to prevent the occurrence of cable failures to minimise the occurrence of cable accidents from the root, from the smallest scratch, and strive to achieve the goal of safe and stable power supply.

Armoured Cable Advantage

1. It can be used to modify the mechanical protective layer of the cable in any one structure above the cable. It can make the mechanical strength of the cable to enhance, and will play the effect of anti-erosion, it can avoid mechanical damage or corrosion, so as to design the wire and cable. It can use any method to lay, and steel belt modification of the cable is laid flat, it will withstand the horizontal direction of an external force. And the steel wire armoured cable is installed in the vertical installation position such as vertical shaft.


2. And after adding the armour layer on the cable, it can make its tensile strength to be enhanced, and its strength will also be enhanced, so as to make the mechanical use of the long time to enhance. And the armouring cable's resistance to external forces is particularly good, can avoid heavy to tear. And its armour layer can be grounded for use, it can protect the cable.


Armoured Cable Characteristics

1. With a hard structure, can effectively protect the cable will not be outside the mechanical force damage, but also can enhance the tensile strength, compressive strength and other mechanical protection to extend the service life.


2. With anti-erosion ability, can protect the cable is not afraid of animal bite and acidic rain corrosion; can use any kind of way laying, more suitable for the harsh environment of buried laying.


3. The armour protection layer can be added to any structure of the cable, but also can be grounded.


4. Generally fixed in a place basically does not move, power transmission of electrical energy or control signal transmission.



Armoured Cable Structure

1. Armouring indicates that the outermost protective layer of the cable is made of steel tape or steel wire winding, which is used to protect the cable from the damage of external mechanical force; while cross-linked cable refers to the cable conductor outside the insulating layer material is made of cross-linked polyethylene material. Can be armoured cross-linked polyethylene cable, that is, the use of cross-linked material insulation, armour outer layer of protection of the cable.


2. Commonly used armouring materials are steel tape, steel wire, aluminium tape, aluminium tube, etc., of which steel tape, steel wire armouring layer with high permeability, good magnetic shielding effect, can be used for low-frequency interference, and can make the armouring of the cable laying directly buried and exempted from the wear pipe and inexpensive, in the actual project use more.


3. Armoured cable code is expressed as: ordinary cable + digital, YJV on behalf of ordinary cable, YJV22 on behalf of armoured cable.


YJV22’ as an example, the first “2” that double steel belt armouring, the second “2” that polyvinyl chloride sheath, such as polyethylene sheath to the The second ‘2’ means PVC sheath, if polyethylene sheath is used, the ‘2’ can be changed to ‘3’.

ABOUT USE

1. Armoured cable is generally fixed power cable. Generally fixed in one place, basically immobile, power line transmission of electrical energy.


2. Suitable for underground direct burial, can make armoured cable not through the pipe direct burial, and inexpensive, very suitable for rocky areas direct burial.


3. Armoured cable is suitable for roads, roadsides, residential areas, car parks, pedestrian streets and other places of high pressure.


4. The purpose of adding an armour layer in the cable is not only to enhance the mechanical protection such as tensile strength and compressive strength, but also to improve the anti-interference performance of the cable through shielding protection.


5. Commonly used armouring materials are steel belt, steel wire, aluminium belt, aluminium tube and so on. Among them, the steel belt and steel wire armouring layer has high magnetic permeability and good magnetic shielding effect, which can be used to resist low-frequency interference.


6. The mechanical protection layer of armoured cable can be added to any structure of the cable to increase the mechanical strength of the cable and improve the corrosion resistance. This is a kind of wires and cables designed for areas susceptible to mechanical damage and corrosion.


7. Armoured cable's have a certain resistance to external forces, but also against the tearing of rats, not through the armour to cause power transmission problems. The bending radius of the armour should be large and the armour layer can be grounded to protect the cable.



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


Armoured cable and non-armoured difference


1. The construction of the two is not the same, armoured cable and non-armoured cable compared to the surface of an additional layer of metal reinforcement.


2. The scope of application of the two is not the same, armoured cable surface has a reinforcing layer, suitable for use in the buried underground, while the surface of the non-armoured cable does not have a reinforcing layer, so the general can not be buried in the ground applicable, but other cases are generally used in non-armoured cable.


And the use of armoured cable as well as non-armoured cable is different. Armoured cables are used when buried in the ground. Armoured cables are used in direct burial and laying. Whereas non-armoured cables cannot be used when buried in the ground, non-armoured cables are used in all other cases.

Armoured cable and ordinary cable differences
1. Both structure is different

Compared with ordinary cables, armoured cables have a layer of metal reinforcement on the surface.

2. Different scope of application

Armoured cable surface has a reinforcing layer, suitable for buried when used, while the ordinary cable surface has no reinforcing layer, can not be buried in the ground, but in other cases generally use non-armoured cable.

3. Both different uses

Armoured cables are used when buried underground. In direct burial and laying, the need for armoured cables. Non-armoured cables cannot be used when buried underground, but in other cases non-armoured cables are used.
