UL 5107 6 AWG Mica Glass Power Wire Overview
UL AWM Style 5107 is a single or multiple conductor construction with other-than-extruded insulation, supplied by CableApex as a factory-direct manufacturer. This product page covers a single-conductor 6 AWG configuration within Style 5107’s broader 26 AWG–550 kcmil conductor range, commercially positioned around the qualified 450°C construction. The wire is rated 600 Vac, using mica tape with treated glass braid insulation. UL defines the Style’s use as internal wiring of high-temperature equipment under specific conditions; “power wire” is CableApex’s commercial positioning for this product, not UL’s own terminology.

6 AWG Stranded Conductor Construction
UL Style 5107 specifies solid or stranded construction for 26–8 AWG, but stranded only for sizes larger than 8 AWG. Since 6 AWG is larger than 8 AWG, this featured product is stranded only — a solid-conductor option is not offered for this size. We do not publish strand count, strand diameter, bunching pattern, or lay length, as none of these are established by the Style-level record; these details are confirmed according to the ordered specification. Conductor material and plating are likewise not established at the Style level and should be specified when requesting a quotation.
Mica Tape and Treated Glass Braid Insulation
UL Style 5107’s insulation system consists of mica tape with a treated glass braid, or, according to the qualified construction, a mica-composite system with braid. We do not invent the detailed composition of a mica-composite construction unless the relevant technical basis is separately supplied for a specific order — qualified Style 5107 constructions may use mica tape or the applicable mica-composite insulation system with braid. The treated glass braid may carry a silicone varnish or TFE finish according to the qualified construction; this page does not fix the braid treatment to one option unless that is the selected commercial construction. This is a mica-and-braid insulation system, not a conventional extruded jacket — we do not describe the basic UL 5107 construction as silicone jacketed, PVC jacketed, rubber jacketed, or fluoropolymer jacketed.
30-Mil Mica and 15-Mil Glass-Braid Requirements
6 AWG falls within Style 5107’s 11–4 AWG insulation band, which specifies a minimum average total mica tape thickness of 30 mils and a minimum average treated glass braid thickness of 15 mils — distinct from the Style’s other bands (26–12 AWG: 25 mil mica / 7 mil braid; 3–4/0 AWG: 35 mil mica / 20 mil braid; 250–550 kcmil: 40 mil mica / 20 mil braid). We do not calculate or publish a finished outside diameter from AWG and these construction thicknesses, as conductor geometry and manufacturing tolerances are not part of the confirmed technical basis for this page.
UL 5107 Technical Specifications
See the specification table above for the complete confirmed ratings and construction elements applicable to this featured 6 AWG single-conductor product. UL Style 5107 also permits, at the Style level, an optional multiple-conductor assembly of two or more insulated conductors cabled together with a maximum overall diameter of 1.500 inches, using an optional mica glass binder and/or fiberglass fillers, with an optional treated glass braid over the assembly. This page’s product is the single-conductor 6 AWG configuration — the optional multi-conductor assembly is a separate procurement intent and is not the basic construction described here.
Protected High-Temperature Equipment Internal Wiring
UL Style 5107’s confirmed use is internal wiring of high-temperature equipment where the wire is not subjected to repeated flexing and is protected from mechanical abuse, with acceptability — including current-carrying capacity — determined by the applicable UL evaluation. Appropriate commercial application language for this page includes protected internal power connections in high-temperature equipment, internal terminal-to-component connections in high-temperature equipment, and high-temperature OEM equipment internal wiring where Style 5107 is specified. Where equipment examples such as ovens or similar thermal equipment are mentioned, they are presented only as equipment-context examples, not as unrestricted suitability for every furnace, kiln, oven, or heater. This page does not position UL 5107 for direct flame exposure, burner flame contact, combustion-chamber flame, or glowing heating-element contact, and does not describe the wire itself as a resistance heating element, heater coil, or heating cable — it carries electrical connections; it is not itself a heat-generating component.
Why UL 5107 Is Not a Flexible Power Cable
The UL use statement explicitly restricts this Style to applications not subjected to repeated flexing. This page does not describe UL 5107 as flexible, extra-flexible, highly flexible, or continuous-flex, and does not publish flex-cycle data or a dynamic bend radius. The wire must also be protected from mechanical abuse in service — this is an installation requirement, not a claim that the wire itself is abrasion-proof, crush-resistant, or impact-resistant. A 450°C temperature rating likewise does not mean the product is fireproof, flame-proof, or capable of surviving open-flame or direct-flame exposure; it remains a high-temperature AWM internal-wiring construction used within protected routing.
UL 5107 vs Fluoropolymer and Silicone Power Wire
UL 5107 represents the extreme-temperature mica/glass branch of CableApex’s Power Cables portfolio, distinct from our other Styles by both material system and temperature ceiling. Our UL 1727 10 AWG PFA Power Wire (250°C / 600 Vac) and UL 1330 4 AWG FEP Power Wire (200°C / 600 Vac) use fluoropolymer insulation, while our UL 3071 18 AWG Silicone Power Wire (200°C / 600 Vac) uses extruded silicone rubber — all lower-temperature and differently constructed than UL 5107’s qualified 450°C mica-and-braid system. No Style is universally superior; the appropriate construction depends on the specified temperature, voltage, routing, mechanical protection, equipment qualification, and conductor size for your specific project.

UL Marking and Documentation
Qualifying UL AWM Style 5107 constructions can be supplied through the relevant qualified manufacturing scope for this Style. UL marking and documentation are confirmed according to the qualified Style 5107 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.
