What is the performance difference between steel tape armored power cable and thin steel wire armored power cable?


Armored power cable is to add an armor layer to the structure of the cable to make the outer sheath more solid, and the internal structure is not easily damaged by the outside, so the main purpose of the steel tape armored cable and thin steel wire armored cable What's the difference? Jinshui Cable Group will tell you about the knowledge of armored cables.

Armored power cables are used in fixed lines with an AC rated voltage of 35KV and below in various fields for power transmission and distribution. It is made of different material conductors installed in metal sleeves with insulating materials, and then processed into flexible and solid cables. It is mainly used for temperature measurement, signal transmission and special cables in chemical industry, metallurgy, machinery manufacturing, power generation and scientific experiments. For heating, the armored thermocouple is used in a large amount. The armored power cable mechanical protection layer can be added to the cable of any structure to increase the mechanical strength of the cable and improve the ability to resist erosion. It is a cable designed for areas that are susceptible to mechanical damage and erosion. It can be laid in any way, and it is more suitable for direct burial laying in rocky areas.

Wiring requirements for armored power cables
1. High compressive strength;
2. Small medium loss;
3. Conductor link;
4. High mechanical strength;
5. The seal is reliable and can prevent moisture intrusion;
6. Small size;
7. Simple structure, easy to process.

Armored Power cables are also divided into steel tape armored cables and steel wire armored cables.
In cables, the steel wire armor is a steel wire mesh or copper wire mesh, and the steel tape armor is a narrow iron sheet. Steel tape armored power cables can be used when the cable is under pressure, and steel wire armored cables can be used when the cable is under tension.
The role of steel wire in steel wire armored cables:
1. Mechanical protection: Steel wire armor can provide mechanical protection for the inner conductor and insulation layer of the cable, preventing external physical damage, extrusion and other factors from damaging the cable.
2. Strength enhancement: Since steel wire has high tensile strength, the use of steel wire armored cables can effectively increase its overall strength and stability in some situations that need to bear large tension or heavy loads.
3. Anti-rat bite: In some special environments (such as field construction, construction sites, etc.), it is easy to be bitten by mice. The cable with steel wire armor can effectively prevent mice from further gnawing on the wire after removing the insulation layer, thereby prolonging the life of the wire.
4. Improvement of fire resistance: Since steel is not easy to burn when it exists alone, in some special occasions (such as ships and nuclear facilities), it is necessary to use refractory materials with metal sleeves or metal mesh sleeves to wrap wires to improve their performance. fire performance.

Performance difference between steel tape armored power cables and thin steel wire armored cables
1. Application: Steel tape armoring is only used for laying of direct buried cables or ordinary pipes, ordinary ground, tunnels, etc. The thin steel wire armor can withstand general longitudinal tension, so it is suitable for short-distance overhead laying or vertical, vertical laying.

2. Price: The corresponding steel wire armor is more expensive. Because the production of steel wire armor is more difficult and the cost is higher.

3. Current-carrying capacity: there is little difference, but the reverse magnetic steel strip or steel wire must be used.

4. According to different use environments, choose different types of armored cables: steel tape armor can withstand mechanical pressure, and steel wire armor can withstand mechanical tension.
