35mm 3 Core SWA Cable Specifications and Applications for Reliable Electrical Installations

Understanding 35mm² 3 Core SWA Cable Key Features and Applications

In the realm of electrical installations, particularly in commercial and industrial settings, the choice of cable is crucial. One notable option is the 35mm² 3 core Steel Wire Armoured (SWA) cable. This type of cable is well-regarded for its robustness and reliability, making it a popular choice for a variety of applications.

What is 35mm² 3 Core SWA Cable?

The term 35mm² refers to the cross-sectional area of the conductors, which in this case is 35 square millimeters. This dimension indicates the cable's ability to handle electrical current; a larger cross-section allows for a higher current capacity, making it suitable for significant loads. The 3 core designation means the cable consists of three individual conductors, typically labeled as phase, neutral, and earth. The inclusion of an earth conductor is essential for safety and compliance with electrical standards.

The SWA indicates that the cable is armored with steel wire, providing additional mechanical protection against physical damage. This feature makes SWA cables particularly advantageous in environments where cables may be exposed to potential impacts, abrasions, or rodent attacks.

Key Advantages of 35mm² 3 Core SWA Cable

1. Durability and Protection The steel wire armoring offers superior protection against mechanical stresses. This makes the cable suitable for outdoor installations, in hazardous locations, or industrial environments where cables are likely to be subjected to physical impacts.

2. Safety The presence of an earth conductor enhances the safety of installations. In the event of a fault, the earth conductor provides a safe path for fault currents, reducing the risk of electric shock or fire.

3. Current Handling Capacity With a cross-sectional area of 35mm², this cable can handle substantial current loads, making it ideal for heavy machinery, power distribution, and larger electrical installations.

4. Versatility 35mm² 3 core SWA cables are used in a variety of applications, including power supplies to commercial buildings, underground installations, and in renewable energy systems like solar panels and wind turbines. Their robust nature allows for versatile deployment in various conditions.

5. Weather Resistance SWA cables are designed to withstand harsh environmental conditions. The insulation materials used are usually resistant to moisture, UV radiation, and temperature changes, ensuring longevity even when exposed to the elements.

Installation Considerations

When installing 35mm² 3 core SWA cables, several factors must be taken into account to ensure safety and compliance with local electrical regulations.

- Bending Radius Care must be taken to respect the minimum bending radius during installation to prevent damage to the cable. - Termination Proper termination is critical. Use suitable connectors and ensure that the earth continuity is maintained throughout the installation. - Burial Depth For underground installations, local regulations often specify the required burial depth. The cable should be protected with suitable conduit if it will be buried in locations where it may be exposed to higher risks of damage.

Conclusion

The 35mm² 3 core SWA cable is an excellent choice for a wide range of electrical applications requiring durability, safety, and reliability. Its robust design and ability to handle substantial current loads make it particularly suited for industrial environments and outdoor installations. Understanding its features, benefits, and installation considerations is crucial for anyone involved in electrical engineering or installation services. By choosing the right cable, professionals can ensure efficient and safe operations, protecting both the systems they design and the individuals who rely on them. Whether for new projects or upgrades to existing systems, 35mm² 3 core SWA cable stands as a dependable solution in the electrical cabling landscape.
