UL 5390 Mica-Glass Wire, 550°C 300V

UL 5390 wire selection

UL 5390 is a UL-certified mica-glass wire rated 550°C and 300 V AC for internal equipment wiring. Its high-temperature insulation system combines mica with a treated fiberglass braid around the conductor.

The dimension table gives six stranded nickel-coated copper configurations from 24 AWG to 14 AWG. Every row identifies UL 5390 with the wire size and includes strand count, finished diameter, approximate weight and minimum bend radius. A separate thickness schedule covers the wider 24–4 AWG style range. This keeps dimensioned constructions distinct from the broader conductor sizes permitted by the style.

For a hot-zone equipment lead, confirm the temperature at the wire and termination, the required operating voltage and the space available for a supported route. The 550°C rating does not increase the 300 V voltage rating. The optional stainless-steel braid shield is a separate construction choice and should be stated on the order if required; it is not included in the unshielded dimension table.

Aufbau

UL 5390 uses the following conductor and insulation system. The diagram illustrates the layer sequence; select the conductor construction and covering shown in the required size specification.

Anwendungen

UL 5390 is intended for internal equipment wiring requiring a 550°C mica-glass construction at 300 V AC. Review the hot-zone route, terminal materials and mechanical protection together before selecting the conductor size.

Technische Daten

Unshielded 550°C, 300 V construction dimensions for selection. Values are nominal; the quotation drawing defines the supplied construction.

Style construction thicknesses are shown in mils; 1 mil = 0.0254 mm. Nominal finished dimensions are listed separately.

Auswahl der spezifizierten Ausführung

Specify UL 5390 with AWG, conductor material, 300 V AC duty and any shield requirement. Use the selected row for nominal OD, weight and bend radius, and request a drawing for sizes beyond the dimensioned table.
