Explore our extensive selection of single core cables, including switchgear and tri-rated cables, hook-up and equipment wires, as well as thermocouple and high-temperature wires.
What is a Wire?
A wire is a single strand of metal, or multiple strands together in a single insulated sleeve. They send and receive telecommunications signals, bear mechanical loads and can transfer electricity. Wires are available in different sizes and types such as solid, single core, stranded, and braided.
What is a Single Core Cable?
Single core means that there is a single piece of metal wire, typically copper or aluminium, with insulation around it. The wire can be different gauges, as the size of the wire increases, the flexibility will generally decrease.
What is the Difference Between Wires and Single Core Cables?
The terms "wire" and "single core cable" are often used interchangeably, though they can denote specific types. Essentially, if a wire consists of a single strand, it qualifies as a single core cable.
Types of Wires
The following are the most common types of wires available in Singapore, each can be used for different types of projects that are commercial, industrial, and even personal.
- Braided Wire: Composed of small strands of wire braided together and enclosed in an insulated sleeve, braided wire is known for its excellent conductivity and durability. It’s often used for noise reduction or EMI shielding.
- Harsh Environment Wire: Specifically designed for environments with high temperatures or exposure to damaging substances such as oils, UV light, acids, and alkalis, this wire is built to withstand extreme conditions.
- High-temperature Wire: Typically featuring a copper conductor with a nickel coating, this type of wire has an insulator material that resists high temperatures, making it ideal for demanding environments.
- Hook-up and Equipment Wire: Usually a single insulated conductor wire, this type is ideal for low-voltage, low-current applications. Common uses include internal computer wiring, consumer electronics, appliances, control panels, and certain areas of vehicles.
- Thermocouple Wire: Used in thermocouples, this wire runs from the sensor point to the cold junction compensation (CJC) endpoint to accurately measure temperature signals.
Types of Single Core Cable
Single core cables are particularly suited for fixed installations and internal wiring of various devices. These cables vary significantly based on their construction:
- **Copper Gauge: **The size of the copper conductor directly affects the cable's capacity to handle certain voltages and operate within specific temperature ranges.
- Insulation Type: The type of insulation used also dictates the environments and applications suitable for the cable, impacting its resistance to heat, cold, and chemical exposure.
- Tri-rated Cable: Also known as panel wire, this type of single core cable is flame retardant and equipped with high-quality insulation, making it suitable for high-temperature environments where it can operate continuously.
Advantages of Single Core Cable
Single core cables offer several distinct advantages that make them suitable for various applications, especially where high-quality performance and durability are required:
- High Insulation Performance: Single core cables are designed with superior insulation materials that enhance their ability to operate safely under various environmental conditions.
- Reduced Electromagnetic Interference: With fewer conductors than multi-core cables, single core cables generate less electromagnetic interference, ensuring clearer signals and reducing potential disruptions in sensitive equipment.
- High Current Capacity: The design of single core cables allows them to transmit high voltages efficiently over long distances without significant power loss, making them ideal for extensive electrical grids.
- Flexibility and Ease of Installation: The inherent flexibility of single core cables makes them easy to install in tight spaces, capable of bending around obstacles without damage, which simplifies the installation process.
- Durability: The robust construction of single core cables, combined with high-quality materials, makes them more resistant to wear, environmental factors, and mechanical stress, thereby extending their lifespan.
Industrial Applications of Single Core Cables
Single core or 1-core cables are essential in various industries due to their high insulation performance, durability, and ability to handle high voltages efficiently. Here’s how they are utilised across different sectors:
- Power Generation and Transmission: Single core cables are crucial in electrical grids for the long-distance transmission of high voltages, ensuring reliable power supply with minimal loss across extensive networks.
- Oil and Gas: In the oil and gas industry, these cables support the operations of heavy machinery and safety systems by providing dependable power transmission under harsh conditions.
- Chemical and Petrochemical: Single core cables withstand the aggressive environments of chemical processing plants, ensuring safe and efficient power management.
- Metallurgical: These cables are used in metallurgical processes where high temperatures and mechanical stresses demand cables that can perform without degradation.
- Mining: Due to their robust construction, single core cables are ideal for the mining industry, where they power equipment deep underground, resisting moisture and mechanical damage.
- Building Construction: In construction, single core cables facilitate the reliable distribution of power within buildings, supporting everything from basic lighting to complex HVAC systems.
