The specification naming rules for automotive high-voltage wires usually follow the following format:

The name or abbreviation of the manufacturer of the cable (e.g. OMG); the number represents the wire gauge in millimeters; T means that this wire is a high voltage wire for ignition systems; and the number represents the length of the wire in meters.

For example, a high-voltage wire with the specification OMG EVRP-125 16 square means that this is a high-voltage wire for ignition systems with a wire diameter of 16 mm and a voltage resistance of 1500 V produced by the OMG cable manufacturer.

It is important to note that the naming of the specifications of the high voltage cable may vary slightly from manufacturer to manufacturer, but some will use a special definition to follow this format above.
