Single conductor cables, also known as Hook-Up Wire, refers to a single insulated wire carrying current in a circuit. The most commonly used single conductor cables are 55A1111-18 and 9-9 models. In this article, we will explore the application field and working principle of these two cables in detail.

Application Field of 55A1111-18

55A1111-18 is a highly versatile single conductor cable, coating with halogen free rubber insulation. This cable offers two different versions of the insulation: standard insulation and extra insulation. In general, these cables are mainly used in the electric industry, such as for power cable and control cable, suitable for indoor and outdoor wiring. Some key applications fields of 55A1111-18 includes:

1. Telecommunications
2. Radio installation
3. Automotive industry
4. Instrumentations and apparatus
5. Signalling and alarm systems
6. Railway or marine applications
7. Lighting systems

Working Principle of 55A1111-18

The working principle of 55A1111-18 is relatively simple. The overall wiring process is divided into two stages: connecting the cable\'s electrical terminals and inserting the cable into the sheath. The electrical terminals are usually composed of a conductor and an insulator. The conductor is composed of metal laminates, which serves as a structure that can carry an electric current, while the insulator prevents other wires from interfering with the electric current. Afterward, the cable is fitted with metal sheath, which acts as a protective layer against outside influences.

Application Field of 9-9

The 9-9 is a single conductor cable specifically designed for general-purpose applications. It is composed of two high-temperature resistant silicone rubber insulation material, which has the ability to resist heat up to 300°C. It can be used in a variety of applications, including electronics, automotive industry, and instrumentations. Some of the key applications include:

1. Internal wiring
2. Communication equipment
3. Pulsed electrical motor
4. Power transistors
5. High speed moving parts
6. General wiring
7. Control systems
8. Measurement circuits

Working Principle of 9-9

The 9-9 is designed with two distinct insulation layers. The inner layer serves as a path for electricity and contains conductive copper wire and a natural copper shield which is coated with a polyester film. The outer layer is a PVC insulation that provides a physical protection against external elements. The combination of these two insulation layers allows the 9-9 to be used in various applications and allows it to withstand extreme temperatures.

In conclusion, the 55A1111-18 and 9-9 single conductor cables are highly versatile products with widespread applications. These cables are suitable for a variety of applications such as electrical industry, automotive industry and instrumentations. Furthermore, these cables come with two distinct insulation layers which allow them to withstand extreme temperatures and provide excellent protection against external elements.
