Multiple Conductor Cables

Multiple conductor cables are cables that consist of two or more conductors bound together under a single outer covering. These cables are used for electronic data transmission and electrical power supply and distribution purposes. Common types of multiple conductor cables are twisted pair cables, shielded cables, and coaxial cables. The 78108 SL001 is a multiple conductor cable from the 78108 series designed by Belden, Inc.

Application Field

The 78108 SL001 is a flexible 22AWG cable with 72 thermocouple conductors in a Neoprene jacket. This type of cable is ideal for use in logging tools, wire-tracing jobs, and in applications where a wide range of temperatures and extreme environmental conditions are present. It can also be used for a variety of commercial, industrial, and home applications, including point-to-point connection.

Construction and Design

The main structure of the 78108 SL001 consists of 72 individual thermocouple conductors that are arranged in six parallel bundles and are separated by a layer of cotton filler material. Each individual thermocouple conductor is a twisted pair of two different precision-glass-clad-magnesium (PGCM) alloys with a polyester binder. The jacket is a jacket of Neoprene insulation with a stainless steel shield. The shield consists of aluminum mylar and a drain wire.

Working Principle

Thermocouple wires generate a voltage when the temperature at the junction of the two metals changes. This voltage can be detected and measured to determine the temperature at the location of the junction. In the case of the 78108 SL001, the shield serves as a ground cord and helps to prevent interference and distortion of the thermal signal. This ensures accurate thermal readings even in extreme environmental conditions.

Conclusion

The 78108 SL001 from Belden is a multiple conductor cable designed for a variety of applications, including logging tools, wire-tracing jobs, and point-to-point connections. Its design consists of 72 individual thermocouple conductors in a Neoprene jacket with a stainless steel shield. The shield serves to prevent interference and distortion of the thermal signal, ensuring accurate thermal readings in a wide range of environmental conditions.
