Single Conductor Cables (Hook-Up Wire) are widely used in a variety of applications across multiple industries and are often referred to by their UL designations or product numbers. One such product is 55A1812-22-9-3, a shielded communication cable. This cable is UL-listed with an operating voltage of 300 volts and is composed of two components: an inner conductor and an outer shielding. The inner conductor is typically a stranded, soft drawn copper material and the outer shielding usually consists of a helical wrap of copper wire. This particular cable is suitable for a variety of applications, including data communication, control, and comfort systems.

The primary purpose of the 55A1812-22-9-3 is to allow a signal to be transmitted from one point to another with minimal interference. This is accomplished by the aforementioned copper shielding which is designed to act as a protective barrier to prevent outside noise or electromagnetic interference (EMI) from entering the cable. The outer insulation of this cable is usually a Polyvinyl Chloride (PVC) which provides additional protection to the copper wire shielding and helps maintain the cable’s electrical properties in extreme temperatures.

The UL specifications for this particular cable include: a maximum operating temperature of 105°C, a minimum bend radius of 7.5x diameter, and a voltage rating of 300V (RMS). In addition, 55A1812-22-9-3 meets the UL 1666 Plenum cable combustibility requirements, which is vital for meeting building code requirements.

In terms of its applications, 55A1812-22-9-3 is ideal for industrial and commercial uses, as well as residential applications. It can be used as a baseboard or grounding common for a variety of applications such as data communications, control systems, security systems, and comfort systems. It is also ideal for applications that require communication lines to be installed in tight spaces, such as behind walls or along ceilings.

The standard working principle for any shielded communication cable is that the signal going through the cable is surrounded by a shielding layer which helps to reduce the amount of interference from external sources. This is why the 55A1812-22-9-3 is able to reduce the amount of EMI that enters the cable from external sources such as power lines and electric motors. The shielding is also able to reduce the amount of reflected or “bounce-back” signal that can occur when signals are transmitted over long distances.

In conclusion, 55A1812-22-9-3 is a shielded communication cable consisting of two components: a stranded conductor and an outer shielding layer of copper wire. This cable is designed to reduce EMI and “bounce-back” signals, allowing for more reliable signal transmission and data communication. It is UL-listed and suitable for installations in commercial, industrial, and residential settings.
