Our selection of electrical cables ensures you'll find the perfect fit for any application. With our team's expert guidance at RS, the leading industrial cables manufacturer in Australia, selecting the right cable becomes straightforward. The correct type of cable for specific uses is crucial for operational efficiency, safety, and durability. High-quality materials and precise construction standards guarantee optimal performance and longevity, making choosing the right cable essential.
What is an Electrical Power Cable?
Electrical power cables are used to transmit electricity from one point to another. Depending on their final application, cables can have different configurations and must always comply with national and international regulations. They consist of three main components:
- Conductors: Usually made of copper wires or aluminium, conducting electricity.
- Insulation: Prevents conductors from touching each other, avoiding short circuits.
- Outer Sheath: Encases all internal components, providing additional protection.
How to Choose the Right Type of Cable?
Choosing the right type of electrical cable is essential for ensuring the safety and efficiency of your devices. Whether you're involved in construction, manufacturing, or telecommunications, understanding how to choose the correct cable can prevent system failures and enhance performance. Here are the factors to consider when selecting an industrial cable:
- Working Environment: The conditions under which the electrical cable will operate influence the choice of sheath material and its thickness. Consider factors such as exposure to chemicals, extreme temperatures, and mechanical stress when selecting a cable that can withstand these conditions.
- Current Capacity: Choosing an electrical cable that can handle the expected current load without overheating is crucial. The current capacity of a cable is determined by its conductor size and the material's ability to withstand high temperatures.
- Safety: Always select a cable that complies with local safety regulations and standards. This ensures the cable performs reliably and prevents electricity-related hazards, such as fires and electrical shocks.
- Short Circuit Rating: This rating indicates the maximum current a cable can carry briefly without sustaining damage. A higher short circuit rating means the cable can handle unexpected surges better, providing an extra layer of safety.
- Voltage Rating: The voltage rating of a cable indicates the maximum voltage it can safely carry. Ensure the cable’s voltage rating is suitable for your system to avoid insulation breakdown and other electrical faults.
What Are the Different Types of Industrial Cables?
Understanding the variety of electrical cables available is crucial for selecting the right type for your specific needs. Here’s a breakdown of the common types:
Mains Power Cable
Mains power cables are versatile and durable, ideal for wiring household appliances and other general applications. They typically feature PVC, rubber, or CPE outer sheaths, which provide flexibility and resistance to environmental factors. These cables may have 1 to 5 stranded or solid copper cores, allowing for efficient power transmission.
SWA Cable
Steel Wire Armoured (SWA) cables have galvanised steel wire insulation surrounding the cores and braiding for added protection and strength. They're generally used in underground cabling but are suitable for indoor or outdoor installations. Sheath material is either PVC (plastic) or LSZH ("Low Smoke Zero Halogen"), which creates less smoke when burned than standard plastic.
Conduit Cable
Conduit cables are specifically designed for installation in conduit systems, providing protection in hazardous environments such as areas with high fire risk or chemical exposure.
Multicore Cable
Multicore cables are used where multiple signals or power feeds are required. They can be configured with 2 to 20+ cores, and the screening helps reduce external interference, ensuring signal integrity and quality.
Australian Cabling Standards & Regulations
In Australia, the installation and use of electrical power cables are tightly regulated to ensure they meet strict safety and performance standards. Here are the key aspects of cabling standards and regulations you should be aware of:
- Compliance with International and National Standards: Australian cabling must adhere to specific standards such as those set by the International Electrotechnical Commission (IEC) for electric cables (TC 20), and the Australian Wiring Rules (AS/NZS 3000:2018). These standards ensure that the cables are safe, reliable, and capable of performing under the specified conditions.
- Certification Requirements: Cables used in Australia often require certification to demonstrate that they meet relevant standards. Look for quality marks such as the Regulatory Compliance Mark (RCM), indicating that a cable complies with the necessary Australian regulatory requirements.
Industrial Applications of Electrical Cables
Electrical power and industrial cables are integral components across a diverse range of industries. Their versatility and reliability make them indispensable in various applications:
- Discrete Manufacturing: In discrete manufacturing, where precision and reliability are paramount, electrical cables are used extensively to power and control machinery. High-quality cables ensure uninterrupted production lines and reduce downtime, directly impacting productivity and operational efficiency.
- Process Manufacturing: Process manufacturing industries, such as chemicals and pharmaceuticals, rely on robust electrical cables to withstand harsh environments and maintain continuous operations. Specialised cables designed to resist chemical corrosion and extreme temperatures are critical in these settings.
- Energy & Utilities: For the energy sector, including power generation and distribution, electrical cables must meet high standards for safety and durability. These cables are often designed to handle high voltages and are crucial in transmitting power over long distances with minimal loss.
- Facilities & Intralogistics: Within facilities and intralogistics, cables are used in automation systems and for connecting various sensors and control units. Flexible and durable cables are essential for dynamic environments like automated warehouses and distribution centres.
By understanding the specific requirements of each industry, RS ensures that our range of electrical and industrial cables meets the highest standards for safety, efficiency, and reliability.
