Magnet Wire
Insulated wire intended for use in windings on motor, transformer and other coils for electromagnetic devices.

Marker Tape
A tape laid parallel to the conductors under the jacket in a cable, imprinted with manufacturer's name and/or specification to which the cable is made.

Marker Thread
A colored thread laid parallel and adjacent to the strand in an insulated conductor which identifies the manufacturer and sometimes the specification to which the wire is made.

A unit for measuring radiation dosage.

A testing device that applies a dc voltage to a conductor and measures the resistance (in millions of ohms) offered by the conductor’s insulation.
