3600B/20 1000 Cables, Wires

Multiple Conductor Cables are an essential item in any home or office, serving a wide variety of purposes from generating power to relaying signals. They are a combination of individual insulated conductors enclosed in a flexible outer sheath or a bundle of conductors insulated in a homogenous material. They can come in a variety of colors and thicknesses, and they can be used in a wide range of applications. This article will cover the various types of multiple conductor cables, their application field, and the working principle of these cables.

Types of Multiple Conductor Cables

Multiple conductor cables come in a range of sizes, materials, and configurations, depending on the type and application. Cables may contain two or more conductors, with or without shielding. Commonly used multiple conductor cables include the following:

• Twisted Pair: Twisted pair cables are often used for communication purposes, such as telephone wiring, Ethernet connections, and so on. These cables are made up of two insulated copper conductors twisted together over the length of the cable for better noise immunity. In some applications, shielding is added to the cable.
• Coaxial: Coaxial cables are commonly used for TV and video applications, and consist of a center conductor surrounded by a braided shield. This type of cable is highly resistant to electromagnetic interference, and provides a much clearer signal than twisted pair.
• Multi-Conductor: Multi-conductor cables are often used in applications that require the transmission of multiple signals over long distances. They consist of several individually insulated conductors in a common jacket. Multi-conductor cables are available in a variety of configurations, including twisted pair, shielded twisted pair, parallel conductors, and multiple coaxial configurations.
• Fiber Optic: Fiber optic cables are increasingly being used in newer communications applications, such as high speed data networks. These cables are composed of a bundle of thin fibers of glass or plastic, which transmit light signals rather than electrical signals.

Application Field

Multiple conductor cables can be used for a wide range of applications, from low voltage power to high speed data transmission. Some of the most common applications in which these cables are used include:

• Power Transmission: Multiple conductor cables are commonly used for the transmission of power, from smaller systems, such as those connecting a computer to a power supply, to larger systems, such as those connecting power plants to industrial facilities.
• Data Transmission: Twisted pair cables are often used for data transmission, such as in Ethernet networks, telephone wiring, and so on. Coaxial cables are also used in a variety of digital audio and video applications, such as television broadcasting and cable modem connections.
• Control Signals: Multiple conductor cables are also used to transmit control signals, such as those used in industrial automation. These cables are often composed of multiple shielded twisted pairs which transmit signals over long distances without interference.
• Automotive Wiring: Multiple conductor cables are used in automotive applications, such as wiring for headlights, taillights, and so on. Multi-conductor cables with shielding are typically used in these applications, as they provide enhanced protection from electromagnetic interference.
• Aerospace: Multiple conductor cables are sometimes used in aerospace applications, such as high-altitude flight instrumentation or data transmission. Shielded, twisted pair cables are typically used in these applications, as they provide enhanced protection from interference.
• Military: Multiple conductor cables are often used in military applications, where they must provide increased protection from interference and robustness in a wide variety of conditions.

Working Principle

Multiple conductor cables function by transmitting electrical signals, either between two points or along a single conductor. The way in which the signals are transmitted depends on the type of cable used and the application. For example, in twisted pair cables, the individual conductors are twisted together to create a “loop” effect, which helps shield the cable from external interference. This helps to ensure that the signal remains clear and consistent over the length of the cable.

In coaxial cables, two conductors are used: a central conductor surrounded by a concentric layer of insulation. This helps to shield the cable from external interference and increases the bandwidth of the cable. In fiber optic cables, light signals are transmitted along the length of the fiber, which is composed of thin strands of glass or plastic.

Regardless of the type of cable used, multiple conductor cables allow for the efficient transmission of signals over long distances. This makes them an ideal choice for a variety of applications, from low voltage power transmission to high speed data transmission.
