High Quality 25mm 4-Core SWA Cable for Versatile Electrical Applications

Understanding 25mm 4 Core SWA Cables A Comprehensive Overview

In the world of electrical installations, the choice of cabling is crucial to ensure safety, efficiency, and reliability. One popular option for various applications is the 25mm 4 core Steel Wired Armoured (SWA) cable. This article will delve into the specifications, uses, advantages, and installation aspects of this type of cable, providing insights into why it remains a favored choice in electrical engineering.

What is 25mm 4 Core SWA Cable?

The 25mm 4 core SWA cable is a robust electrical cable designed to withstand harsh environmental conditions. The designation 25mm indicates the cross-sectional area of the conductors, while 4 core signifies that there are four individual conductors within the cable. These cores typically include three live conductors (often colored brown, blue, and black for phase, neutral, and earth, respectively) and one earth conductor, ensuring safe operations in electrical systems.

The SWA component of the name refers to the steel wire armoring that encases the cable. This armor provides a high level of mechanical protection, making the cable suitable for both internal and external applications. It is commonly used in underground installations, industrial environments, and areas where the cable may be exposed to physical stress or environmental hazards.

Key Specifications

The 25mm 4 core SWA cable is designed to carry varying electrical loads efficiently, making it suitable for multiple applications—from commercial and industrial settings to residential projects. Typically, it is rated for voltages up to 600/1000 V (Uo/U), and its temperature rating can range from -15°C to +90°C, depending on the insulation material used. The conductive material is usually copper, renowned for its excellent conductivity, ensuring minimal energy loss during transmission.

Applications
