Lacquer - a liquid resin or compound applied to textile braid to prevent fraying, moisture absorption, etc.

Laminated Tape - a tape consisting of two or more layers of different materials bonded together.

LANCE - Local Area Network for Controller Ethernet

LANS - Local Area Networks System (integration of computer and communication). System that wires together all computers and peripherals in an office so they can talk to each other.

Lay - The length measured along the axis of a wire or cable required for a single strand (in stranded wire) or conductor (in cable) to make one complete turn about the axis of the conductor or cable. In a twisted pair cable, the lay length is the distance it takes for the two wires to completely twist around each other.

Lay Direction - the twist on the cable as indicated by the top strands whole looking along the axis of the cable away from the observer. Described as "right hand" or "left hand".

LDPE - Low-density Polyethylene

Leaching and Non-Leaching - in a leaching wire the plasticizer will migrate when exposed to heat. A non-leaching wire will retain its plasticizer under extreme temperature conditions and remain flexible after baking.

Leakage Current - the undesirable flow of current through or over the surfaces of an insulation.

Life Cycle - a test to determine the length of time before failure in a controlled, usually accelerated, environment.

Limits of Error - the maximum deviation (in degrees or percents) of a thermocouple or thermocouple extension wire from standard emf-temperature to be measured.
