Just what is a 5-CORE CABLE?
Exactly what is 5-core cable? What is actually a core? Plain and simply, a conductor is a copper wire protected by an insulation layer. The layer often contains the materials: PVC, PE, Plastic or Rubber. This protective layer may be stripped so your wire becomes visible. For stripping a cable use a cable stripper the wire comprise of the types of materials: Silver, Gold, Copper or Aluminium.
THE WIRES Of the 5-CORE CABLE
In case you look at a (5 core) cable, they usually consist of several cores plus a sheath that holds these cores together. You do not just have 5 core cables but also cables with 3 cores or 8 cores. The main with the cable will be the wire that's linked to the connector on, as an example, a 5-pin plug. The core is made up of conductor (made of copper) that conducts electricity well. The wire therefore features a low resistance. Different colours are accustomed to clearly indicate the type of function the wire has. Please note that all suppliers use different colours. So it is great for see the manual of the lamp. One more reason for using these casings is always to prevent the wires (cores) from contacting another wires. In case a conductor is made up of several (copper) wires, it is called a stranded wire.
WHY COPPER?
The price tag on copper varies after a while and may therefore be called variable, just like raw materials like gold and oil. However, the advantage of copper could it be is an ideal conductive and flexible material. A lot better than steel or aluminium can. It is a material which has a soft texture which is therefore easy to process. This flexibility helps to make the raw material very suited to, for example, 5-core cables which can be subjected to large mechanical loads as the cable route is within motion. These specifications are making copper the standard material for all those cables.
DOES TEMPERATURE ALSO INFLUENCE CONDUCTIVITY?
Yes, the temperature also affects the conductivity, not simply with 5 core cables but all cables! As the temperature rises, the atoms and electrons gain energy from this. This will cause the conductive material to be expanded. Most metals be more effective conductors if they're cool. Even at extremely low temperatures, some conductors become superconductors. So conductivity can transform the temperature with the material. Electrons therefore flow through conductors without affecting the atoms. Moving electrons experience resistance in the process. This enables an electric current circulation to heat the conducting material.
