The 2722/18 BU/M application field and working principle is a common type of single conductor cables, also known as hook-up wires. These wires are suitable for internal connections and short external wiring runs in all types of equipment, including lighting fixtures, industrial control panels, and household appliances. In addition to this, hook-up wire can be found in cars, boats, and other recreational vehicles.

Construction and Types:

The hook-up wire consists of stranded or solid copper wires covered by an electrically insulating jacket. To increase the durability of the wire, additional layers of insulating materials such as fabric tapes and varnishes may also be added. Commonly used insulating materials include PVC, Neoprene, and PTFE. The diameter of the wire will also vary depending on the application.

Insulation Resistance:

One of the key properties of hook-up wire is its insulation resistance. This refers to the ability of the wire to resists electric current when a voltage is applied to it. The insulation resistance of the hook-up wire is usually expressed in terms of the number of ohms the wire can withstand per foot of its length. Generally, higher insulation resistance indicates better performance of the wire.

Temperature Rating:

The temperature rating of the hook-up wire indicates the maximum operating temperature of the wire before it begins to suffer from thermal degradation. For longer wire runs and higher ambient temperatures, higher temperature rated wires are recommended. The temperature rating of the wire usually ranges from -20 ˚C to 105 ˚C.

Altitude Rating:

Altitude rating of the hook-up wire refers to its ability to tolerate changes in air pressure and changes in air density due to rapid variations in altitude. This rating usually ranges from -500 ft to 10,000 ft.

Corrosion Protection:

The hook-up wire is often encased with a layer of protective material to protect the wire from environmental conditions, such as moisture and corrosive elements. This layer of protection may consist of a sheet of aluminum, an insulating material, or a protective varnish. This layer of protection also helps to increase the overall life of the wire.

Voltage Rating:

The voltage rating of the hook-up wire indicates the voltage that the wire is capable of carrying without suffering from excessive heating or damage. The voltage rating of most hook-up wires range from 0.5 volts (UL approved for wiring in fixtures) to 600 volts.

Flexibility:

The flexibility of the hook-up wire is an important factor when choosing a particular type of wire for a particular application. Flexible wires are generally preferred over stiff wires as they can be used in tight spaces and can be bent and twisted to fit the desired shape and application.

Applications:

Hook-up wire is used in a variety of applications, including electrical connections in building wiring, control and instrument panels, wiring in light fixtures, and wiring in utility boxes. Hook-up wire is also used in automotive and marine wiring applications, as well as in heavy machinery and industrial control panels.

Conclusion:

Hook-up wire is a commonly used single conductor cable suitable for internal connections and short external wiring runs. The wire is composed of stranded or solid copper wires covered in an electrically insulating jacket, and additional layers of insulating materials may also be added to increase its durability. The key properties of the wire include insulation resistance, temperature rating, altitude rating, corrosion protection, voltage rating and flexibility. Hook-up wire is used in many applications, from building wiring to automotive and marine applications.
