Multiple Conductor Cables

Multiple conductor (or multicore) cables are extensively used to transmit signals in the fields of telecom, electrical engineering, computer, and industrial applications. The cables can be grouped into two categories: a multi-pair twisted pair cable and a hard-wired multi-conductor cable. Both types have different characteristics in terms of data transmission speed, signal protection, and data integrity. In this article, we will be discussing the application field and working principle of one of the most popular multiple conductor cables, the 5220/2C SL002.

Application Field of 5220/2C SL002 Cable

The 5220/2C SL002 is a shielded and plenum-rated multi-conductor data cable. It is widely used in the telecom and other industries to provide reliable transmission of digital data such as Ethernet, audio, video, fire-alarm and power. The cable is composed of 18 AWG stranded tinned copper conductors insulated with XEvinyl and covered with a jacket of polypropylene, which makes the cable highly flexible and resistant to abrasion. It is also UL listed and meets UL-ordinance 1666. The cable is suitable for both indoor and outdoor applications.

Working Principle of 5220/2C SL002 Cable

The working principle of the 5220/2C SL002 is very similar to other multi-conductor cables. The copper conductors are arranged according to a particular set of standards. For example, the four-pair twisted cables are organized as a pair for each twisted conductor with respect to the colors used. The twisted pair cables function in a specific way to reduce noise resistance and to ensure compliance to transmission protocols. The individual wires may be configured in different ways to achieve different purposes.

The plenum rated jacket of the cable is designed to minimize fire risk. It is made of thermoplastic polyolefin (TPO) which is combustible and releases toxic gases while burning. The jacket restricts the spread of the fire and also absorbs mechanical shocks. The shield in the cable ensures the integrity of the signal by protecting it from external interference. The shield is made of a copper braid which is covered with a jacket of PVC and functions as a Faraday cage.

Conclusion

The 5220/2C SL002 is a multi-conductor data cable with a number of advantages. It is suitable for both indoor and outdoor applications, UL-listed, and has a high performance in terms of fire protection, signal integrity and noise resistance. Its application field is mainly telecom and other digital data transmission, such as Ethernet, audio, video and fire-alarm systems. The working principle of the cable is based on a set of copper conductors arranged according to specific standards, a plenum rated jacket of thermoplastic polyolefin and a shield layer of copper braid covered with a PVC jacket.
