E3522S.69.03 Multiple Conductor Cables: Application Field and Working Principle

Multiple conductor cables are a type of cable that contains two or more conductors, which are usually insulated and held together using an outer protective sheath. The application field of multiple conductor cables can be substantially varied due to their wide range of uses. These cables have the capability of carrying power, audio, video and data signals. Moreover, because of their insulation feature, they can be used to prevent electric shock. The most common uses of multiple conductor cables include connecting microphones to sound systems, linking AV equipment to TVs and connecting personal computers to each other.

The working principle of multiple conductor cables mainly centres around conduction of electricity. In the presence of electricity, an electrical field is generated between two closely linked electrodes. This electrical field induces a current flow between them. An electrostatic charge can also be created in metallic objects in the same vicinity. Multiple conductor cables are designed in a way that reduces their electrostatic and electrical fields. This is done by alternating the direction of the electrical currents or by shielding the cables that are encased in a protective cover.

In terms of physical structure, multiple conductor cables are composed of various components. Each conductor is typically made of copper or aluminium alloys, however some cables also include other components such as protective dampers, insulation and fillers. Additionally, a jacket or shield material, such as a Mylar foil, is inserted between the conductors to ensure that the fields are reduced.

Depending on the type of multiple conductor cable, there are different types of connections which the components may create. Resistance welding involves applying a low-intensity current between two conductors to create a strong electrical connection. Soldering is a similar process wherein an additional conductive material is used to make the connection. In contrast, crimp connectors are used to join two conductors together by producing a unipolar contact between them. This method involves placing a connector between the two wires and squeezing it down with a specific tool to create a secure connection.

The advantages of multiple conductor cables are mainly linked to their wide range of applications and various features. For example, some types are insulated to protect against electric shocks and contain additional protective layers to shield against external interference. Moreover, the various types of connections found in these cables enable them to remain secure even in adverse conditions.

In conclusion, multiple conductor cables find a large number of applications in day-to-day activities. They perform a variety of functions and offer protection against high voltages. From connecting microphones to sound systems and linking AV equipment to TVs to connecting personal computers, these cables are essential in order to ensure that data, power and audio signals are correctly transferred. The understanding of their components, working principles and connections is essential in order for multiple conductor cables to be used effectively.
