Hook up wire is a single insulated conductor wire that can be used in electronics for low voltage and low current applications. This hook up wire is made from PTFE which can deal with high temperatures, has excellent electrical properties and is resistant to many chemicals and solvents. Hook up wire is frequently used in control panels, automotive, meters, ovens, internal wiring of computers, electronic equipment, business machines and appliances. This type of hook up wire from Alpha Wire can be used in military applications.
