1 Mei 2020 | Selamat menyambut Hari Pekerja kepada semua pekerja di seluruh negara. Semoga kita sentiasa komited memberikan “EXCELLENCE” dalam setiap tugasan yang diamanahkan walaupun berdepan dengan cabaran situasi semasa.
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…
Last week’s post, we shared the composition and material density of copper, aluminium and aluminium alloy. That determines the strength and conductivity of each material. The chart above shows the comparison between copper and three different grades of aluminium. The unique properties of each grade of material makes it suitable for different uses. For instance:…
