UL 3645 wire selection
UL 3645 is a UL-certified covered silicone wire rated 1000 V AC, with 150°C and 200°C constructions. The version shown here adds a fiberglass braid over the silicone insulation for internal appliance or electronic equipment wiring.
The 19-row size table spans 30 AWG through 4/0 AWG and identifies the nominal silicone wall, 0.16 mm glass covering and finished diameter for each listed construction. The outer braid is part of the finished size, so it must be included when checking sleeves, clamps and terminal entries. The separate style schedule covers additional conductor groups up to 750 kcmil without assigning unverified finished diameters to them.
Select the temperature grade and covering before comparing this wire with an uncovered silicone lead. The same AWG and voltage can still lead to a different outside diameter and stripping procedure. For the listed constructions, allow a bend radius of 10 times finished diameter and support the lead so the braid does not rub against sharp equipment edges.
See the Specifications tab for the model and size tables. Browse the high-temperature cable range for related constructions. Compare bare UL 3644 and the lower-voltage braided silicone wire family.
Construction
UL 3645 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.
| Component | Construction detail |
|---|---|
| Conductor | Solid or stranded copper; dimensioned examples are stranded |
| Insulation | Extruded silicone rubber |
| Outer covering | Fiberglass braid; 0.16 mm in dimensioned examples |
Applications
UL 3645 is used for internal appliance and electronic equipment wiring that specifies a covering over silicone insulation. Review the braid finish and termination arrangement where the covering ends near a connector.
UL 3645 replacement selection
For replacement enquiries, include the existing wire marking and the equipment connection drawing so the conductor, insulation and terminal arrangement can be matched.
