WIRE BRAID - Flexible wire constructed of small size strands woven together in tubular form. Used for shielding or connections where constant flexing is required.
WIRE GAUGE - The American Wire Gauge, originally called Brown & Sharpe Gauge. A system of numerical wire sizes starting with the lowest numbers for the largest sizes. Gauge sizes are each 20.6% apart based on cross sectional area. Abbreviation AWG.
WOLLASTON WIRE - Extremely fine platinum wire that is used for electroscope wires, micro fuses, and hot-wire instruments. It is produced by coating platinum wire with a sheath of silver, drawing them together into a relatively fine uniform diameter wire, and then dissolving the silver with a suitable acid. Diameters to about one micrometer may be produced by this method.
WOVEN CABLES - A method of producing a flat or ribbon type cable by holding the conductors together with thread as a result of a weaving process.
X - Symbol for reactance. See reactance.
X BAND - A band of microwave frequencies. See frequency band.
X GUIDE - A transmission line that is used for the propagation of surface waves and consists of a length of dielectric material with a X-shaped cross section.
X-100 - See FEP.
XETFE - Abbreviation for cross-linked extruded, modified ethylene tetrafluoroethylene copolymer. See ethylene tetrafluoroethylene.
XHHW - Cross-linked polyethylene insulated, rated at 90° C in dry locations and 75° C in wet locations.
XL - Abbreviation for cross-linked insulation. See cross-linked.
XL POLYOLEFIN - Cross-linked polyolefin.
