Part 2 (a) – Insulation
There are many types of electrical insulation in use today, with each having unique physical and chemical properties. Most common insulation materials used in electrical cables are made from plastic-polymer-based compounds. Ever wondered why bare conductors used in high voltage transmission systems do not have any insulation? The answer: air is natural insulation between phase-to-phase…

Part 1 (i) – Conductor
Copper and aluminium are primary choices of material for cable conductors due to its mechanical, electrical properties and of course price of the commodity itself. The table above show the comparison between various metals according to the International Annealed Copper Standard (IACS). The diagram on the right illustrates that different material due to different conductivity…

Part 1 (h) – Conductor
The routine test shall be tested on conductor to determine the DC resistance of the conductor at 20 oC and the measured value shall not exceed the appropriate maximum specified in table of IEC 60228 and BS 6360. This type of test is done on a 1 meter sample in a laboratory using a double…

Part 1 (g) – Conductor
Current carrying capacity depends on the cross-sectional area of the conductor and the material it is made from. The complexity of cable routes and environmental constraints such as burial depth, type of soil will also influence the current rating. It is often referred to as “derating factor”. Therefore engineers and designers, when calculating power load…

Part 1 (f) – Conductor
Almost any type of copper or aluminium conductor produced today undergoes concentric stranding to build up to a desired cross-sectional area. For instance it is much more practical and cost effective to produce a 19-wire 35mm2 conductor than to produce a single solid 35mm2 conductor. 101,888 total views

Part 1 (e) – Conductor
Calculating conductor weight is fairly straight forward. No complex formulas here. Simply multiply the conductor cross-sectional area by the material density of that conductor.
