High-Quality 5 Core 4mm SWA Cable for Versatile Electrical Applications

Understanding 5% 20 Core 4mm SWA Cable Features and Applications

The 5% 20 Core 4mm SWA (Steel Wired Armoured) cable is an essential component in the electrical and construction sectors, providing robust connectivity solutions for various applications. With its distinctive features and advantages, it has gained significant popularity among professionals who rely on durability, safety, and performance in challenging environments.

What is SWA Cable?

SWA cable is designed to ensure protection against mechanical damage, which is crucial in industrial and outdoor settings where cables are exposed to harsh conditions. The armoured aspect of SWA indicates that the cable is encased in a layer of steel wire, providing resistance against impact and environmental factors. This is particularly important in applications like buried installations, where the risk of damage from soil movement or external forces can compromise not just the integrity of the cable but also the safety of the electrical system.

Design and Specifications

The “20 Core” aspect of the 5% 20 Core 4mm SWA cable signifies that it consists of 20 individual conductors. This design allows for multiple connections and is ideal for complex electrical systems requiring a range of functions. The “4mm” refers to the cross-sectional area of each conductor, which is critical in determining the current-carrying capacity and overall efficiency of the cable. In general, a larger cross-section allows for higher currents to be carried safely.

The “5%” specification indicates that the cable maintains a minimal voltage drop, with the 5% being the maximum acceptable limit under load conditions. This characteristic is crucial for maintaining the efficiency of electrical installations, particularly over long distances, ensuring that the end devices receive adequate voltage without significant losses.

Key Features

1. Mechanical Protection The steel wire armouring protects against physical damage, making it suitable for outdoor installations or areas with a high risk of wear and tear. 2. Weather Resistance The materials used in SWA cables often provide resistance to moisture, UV rays, and temperature fluctuations, ensuring longevity in outdoor applications.

3. Multi-core Versatility With 20 cores, these cables facilitate complex wiring needs, allowing for various phases, neutral, and earth connections in a single cable, simplifying installation processes.

4. Safety Compliance SWA cables comply with various regulatory standards, ensuring safety and reliability. This is crucial for applications in commercial, industrial, and even residential settings.

5. Cost-Effectiveness Although the initial investment in SWA cables may be higher than standard cables, their durability and low maintenance costs often lead to long-term savings.
