UL 3122 18 AWG Silicone Wire Overview
UL AWM Style 3122 is a single-conductor silicone rubber insulated wire construction, supplied by CableApex as a factory-direct manufacturer. This page focuses specifically on the 18 AWG configuration within Style 3122’s broader 26 AWG–16 AWG conductor range. The wire is rated 200°C and 300 Vac, with extruded silicone rubber (SR) insulation and a lacquered braid covering. This page is a dedicated 18 AWG procurement page, distinct from our existing UL 3122 16 AWG Silicone Wire product.

18 AWG Solid or Stranded Internal Wiring
UL Style 3122 covers a conductor range of 26 AWG through 16 AWG, solid or stranded; this page focuses specifically on the 18 AWG configuration. We do not publish strand count, strand diameter, conductor resistance, or ampacity for 18 AWG or any AWG within this Style, as none of these are established by the Style-level record. Conductor material and finish are also not established at the Style level — this page does not describe UL 3122 as tinned copper, bare copper, oxygen-free copper, or any other specific plating or purity, and conductor material or plating should be specified when requesting a quotation.
15-Mil Silicone Rubber Insulation
The conductor is insulated with extruded silicone rubber (SR) at a minimum average thickness of 15 mils and a minimum thickness of 13 mils at any point. We use this UL terminology precisely — this is a minimum average thickness, not a nominal production dimension, and we do not calculate or publish a finished outside diameter from AWG, insulation thickness, and braid construction, as conductor geometry and manufacturing tolerances are not part of the confirmed technical basis for this page.
Lacquered Braid Covering
UL Style 3122 specifies a lacquered braid as the covering. The supplied Style record does not identify the braid’s fiber material, so this page does not describe it as fiberglass, glass-fiber, or silicone-coated fiberglass braid unless a specific commercial construction independently confirms that material — the safest and most accurate Style-level description is silicone rubber insulated wire with lacquered braid.

Internal Wiring Applications and Use Boundary
UL Style 3122’s confirmed use is internal wiring. Appropriate commercial application language for this page includes equipment internal wiring, appliance internal wiring where the equipment design specifies Style 3122, protected internal electrical connections, internal component-to-component wiring, and OEM internal wiring. Where motors, industrial ovens, furnaces, heaters, or lighting are discussed, they are presented only as possible equipment contexts subject to end-product evaluation — UL does not specifically define this Style for those applications. This page does not position UL 3122 as a resistance heating wire, heater element, heating cable, or heating coil wire; it is electrical internal wiring, not a heat-generating component.
UL 3122 18 AWG vs 16 AWG Procurement
CableApex also offers UL 3122 16 AWG Silicone Wire, sharing the same 200°C / 300 Vac rating and lacquered braid covering. The two pages are not distinguished by any performance difference between the gauges — the Style-level rating, insulation, and covering are the same across the 26–16 AWG range — but by the specific conductor size, dimensional confirmation, and construction requirement your equipment design calls for. When ordering, confirm your required AWG, solid or stranded construction, and exact conductor finish so the correct qualified 18 AWG construction can be supplied, distinct from the 16 AWG product.
What to Specify When Ordering UL 3122 18 AWG Wire
To provide an accurate quotation for UL 3122 18 AWG silicone wire, please specify:
- Confirmation of 18 AWG as the required gauge
- Solid or stranded conductor
- Conductor material or plating requirement
- Operating temperature
- Operating voltage
- Required finished OD or maximum installation space, if applicable
- Insulation or braid colour requirement, if applicable
- Marking requirement
- Order quantity
- Packaging requirement
- UL documentation requirement, including RoHS / REACH if needed
- Equipment type
- Internal wiring application
- Shipping destination
Send this information and we respond with a quotation within 12 business hours. Production lead time depends on the confirmed construction and order quantity, and shipping options and applicable Incoterms are confirmed during quotation according to destination.
UL Marking and Documentation
Qualifying UL AWM Style 3122 constructions can be supplied through the relevant qualified manufacturing scope for this Style. UL marking and documentation are confirmed according to the qualified Style 3122 construction supplied for the order and are not identical across every commercial variation. RoHS and REACH are separate regulatory frameworks from UL recognition; applicable RoHS / REACH documentation requirements can be confirmed according to the ordered construction.
