Structural Properties of Weak Current Cables
Generally Weak current cables consist of 10 different structures.

1. Conductor
2. Vessel
3. Core Insulation
4. Wick-Blind Vein
5. Separating Tapes
6. Inner Sheath and Fillings
7. Screens
8. Separating Cases
9. Metallic Armors
10. Protective Outer Cases

1. CONDUCTOR
It is an insulated or uninsulated wire or bundle of wire, consisting of one or more wires used to transmit electrical energy or electrical signals.

Conductors used in cables are measured with their geometric cross-sections (mm²) or diameters (mm). There are conductors that are also measured by the American measurement system AWG.

The most important feature of the conductor is its electrical resistance. The difficulty of a material against electric current is called resistance.

2. VEIN
It is each insulated conductor of a cable. The vessel consists of the conductive part and the insulating material surrounding it.

3. VESSEL INSULATION
Core insulation is the electrically insulating sheath of the conductor. Insulating materials are non-conductive materials that resist electric current.
These materials are used in the electrical industry to insulate conductors from each other and from their surroundings.

4. WICK-BLIND VESSEL
They are insulating materials used to fill the gaps between the cores in multi-core cables and to ensure proper form of the cable.
Suppositories PVC. It can be PE or HFFR.

5. SEPARATOR TAPES
They are the materials that separate the elements from each other in cable manufacturing. Some of the separating bands serve as separation while others have duties such as fire barrier, moisture barrier and screening.

6. INTERNAL SHEATH AND FILLINGS
Inner sheath: It is the insulating sheath and inner sheaths that are placed between the separating layers.

Fillings: It is the sheath that covers the harness in the multi-core cables and serves to give the harness the desired shape. Inner sheath and filler should generally be suitable for insulation and outer sheath material, and materials can be PVC, PE or HFFR.

7. SCREENS
The purpose of the shielding done on the cables is to ensure that the signals carried by the cables are not affected by electromagnetic disturbing interference in the environment where the cable is located.

8. SEPARATOR SHEATH
It is an insulating cover between separate metals overlapping. Separating sleeves should generally be suitable for insulation and outer sheath material.
These materials can be PVC, PE or HFFR.

9. METALLIC ARMOR
Cables often need additional protection against mechanical impact that can occur during installation and operation.
These armors also function as grounding and screen savers.

10. PROTECTIVE EXTERIOR SHEATHES
It is the material outside the cable that protects the cable from external influences.
