In this video, we will take an in-depth look at steel wire armored (SWA) cables. We will explore the construction and conductor colours in detail. We will cover the different layers of a typical SWA cable, including the outer PVC, steel armor, and bedding material, explaining their roles and functions. Additionally, we will discuss using the steel armor as a protective conductor and when it might need supplementation.

We will break down conductor identification for various configurations, such as two-core, three-core, four-core, and five-core cables, along with considerations for single-phase and three-phase systems. We will also discuss how to interface older pre-2004 cable colours with modern standards to avoid potential hazards.

Throughout the video, we will highlight key exam tips, including identifying cable materials and understanding the properties of thermoplastic and thermosetting PVC. We will also touch on installation practices, such as using appropriate glands and stripping cables.
