Multiple Conductor Cables: 55PC0121-20-0/2 Application Field and Working Principle

Multiple conductor cables are power and control cables with two or more conductors, which are designed for use in direct current (DC) applications such as industrial controls, rectifier systems and subsea cables. The 55PC0121-20-0/2 Multiple Conductor Cable is specifically designed for use in submerged and wet locations. It is a low-voltage, flame-retardant, three-conductor cable with a rated voltage of 600V and an operating temperature range of -30°C to 60°C. This cable is designed for direct burial in mud, earth, and water without the need for additional protection.

The 55PC0121-20-0/2 cable is composed of two separate subassemblies. The first subassembly is a bundle of three stranded conductors consisting of three 19 AWG finewire tinned copper conductors with a polyvinyl chloride (PVC) insulation and a strand-filled jacket. The second subassembly is a black inner jacket composed of a thermoplastic-polyester (TPE) blend that covers the conductor bundle. A black overjacket with a non-metallic rip cord runs over the entire length of the cable.

The physical design of the 55PC0121-20-0/2 cable is designed to provide flexibility while maintaining high strength and durability. The conductors are insulated with a PVC insulation and a thermoplastic-polyester blended jacket. This provides a physically tough insulation layer that is corrosion and abrasion resistant and can withstand high temperatures. The outer jacket of the cable is composed of a thermoplastic-polyester (TPE) blend. This provides a water and UV resistant coating that is also highly resistant to damage and abrasion. Additional protection is provided by the black light-blocking inner jacket. The rip cord allows for easy stripping of the cable when necessary.

The working principle of the 55PC0121-20-0/2 Multiple Conductor Cable is based on the principles of electrical current flow. The conductors are connected to a power source and then connected to a load, such as a motor or light fixture. As the electrical current flows through the conductors, a magnetic field is generated that interacts with the load. This interaction causes the load to move or produce light or heat.

The 55PC0121-20-0/2 Multiple Conductor Cable is most commonly used in industrial applications such as electrical control systems, fabrication machines, and subsea applications. It is designed for use in wet, submerged and buried-in-mud environments where a flexible, durable and long-lasting cable is required. The inner and outer jackets of the cable provide additional corrosion resistance and flexibility. The cable is also rated for direct burial without requiring additional protection, making it a great choice for applications that require underwater cabling.

In conclusion, the 55PC0121-20-0/2 Multiple Conductor Cable is a fan-favorite among engineers and professionals who need a flexible and durable cable for use in wet locations. This cable is designed for direct burial in mud, earth, and water without the need for additional protection. The inner and outer jackets of the cable provide additional protection against abrasion and corrosion. The flexible cable design and high-temperature rating makes it an ideal choice for industrial and submerged applications.
