UL 5107 Multi-Core Mica Glass Braid Cable Overview
This page covers UL AWM Style 5107 mica tape and treated glass braid insulated cable in a multiple-conductor construction, supplied by CableApex as a factory-direct manufacturer. UL Style 5107 covers a conductor range of 26 AWG through 550 kcmil and permits two or more individually insulated qualifying conductors to be cabled together into a multiple-conductor assembly. This page’s primary focus is that multi-conductor construction; buyers requiring a single-conductor UL 5107 construction should confirm that requirement separately during quotation.
UL 5107 multi-core mica glass braid cable is a non-extruded insulation construction, rated 200°C or 450°C depending on the qualified ordered construction, at 600 Vac, built from mica tape or mica composite with a treated glass braid, for internal wiring of high-temperature equipment. Core count, conductor material and finish, braid treatment, and packaging are confirmed according to the ordered specification.

Mica Tape and Treated Glass Braid Construction
Each conductor in a UL 5107 assembly is insulated with mica tape or mica composite, covered by a treated glass braid. The braid may carry a silicone varnish finish or a TFE finish, depending on the qualified construction — this is a braid treatment, not a silicone rubber or PTFE primary insulation, and this product should not be described as a silicone-insulated, FEP-insulated, PTFE-insulated, PFA-insulated, PVC, or XLPE cable. The mica-and-glass-braid system is the defining insulation construction for this Style.
Multiple-Conductor Cable Assembly
Two or More Insulated Conductors
UL Style 5107 permits two or more individually insulated qualifying conductors to be cabled together into a multiple-conductor assembly, with a maximum assembly outside diameter of 1.500 inches. This 1.500-inch figure is the maximum permitted OD for the assembly, not a standard or typical OD — actual finished assembly diameter depends on core count, conductor size, and construction, and is confirmed for the ordered configuration. Core count itself is not fixed by the Style and must be specified and confirmed according to your required assembly.
Optional Binder, Fillers and Overall Glass Braid
The Style permits optional construction features for a multi-conductor assembly: a mica glass binder, fiberglass fillers, and an overall treated glass braid applied over the completed assembly. These are optional, order-specific features rather than standard components of every UL 5107 cable — specify which, if any, are required when requesting a quotation.
UL 5107 Insulation Thickness by Conductor Size
| Conductor Size | Mica Tape (min. avg.) | Treated Glass Braid (min. avg.) |
|---|---|---|
| 26–12 AWG | 25 mil | 7 mil |
| 11–4 AWG | 30 mil | 15 mil |
| 3 AWG–4/0 AWG | 35 mil | 20 mil |
| 250–550 kcmil | 40 mil | 20 mil |
These are per-conductor construction thickness requirements and do not translate into an invented finished cable outside diameter. Conductor material, plating, strand count, and resistance are not established by the Style-level record and are confirmed according to your ordered specification.
High-Temperature Equipment Internal Wiring
UL Style 5107 is designated for internal wiring of high-temperature equipment. This is the application boundary for the product supplied from this page: high-temperature equipment internal wiring, protected internal wiring assemblies, and fixed multi-conductor internal connections. It is not intended as building wire, field wiring, branch circuit cable, tray cable, outdoor or direct-burial cable, or general industrial power cable, and this page does not position the product for robotic, servo, drag-chain, automotive, EV, marine, or aerospace applications.
Repeated Flexing and Mechanical Protection Limitations
The UL Style use statement specifies that this cable is not subjected to repeated flexing and must be protected from mechanical abuse. UL 5107 is not described on this page as super-flexible, ultra-flexible, continuous-flex, or suitable for millions of flex cycles — those characteristics fall outside its UL-supported use. We do not publish a bending radius, as none is confirmed by the supplied UL record. Installation should route and secure the assembly along a fixed or protected path rather than in a repeated-motion application.
UL Marking and Order Documentation
Qualifying UL AWM Style 5107 constructions can be supplied through the relevant partner manufacturing scope associated with the applicable UL Recognized Component file on record. UL marking and related documentation depend on the specific qualified construction ordered; not every configuration automatically carries a UL Mark, and marking requirements should be confirmed when requesting a quotation. Current-carrying capacity for a given construction is subject to the applicable UL determination based on the actual conductor size, assembly, and installation conditions — this page does not publish a generic ampacity table. We do not guarantee that a given shipment will pass a customer’s internal or third-party audit, certification review, or project bidding requirement.
RoHS and REACH are separate regulatory frameworks from UL recognition and are not treated as equivalent certifications on this page. Applicable RoHS / REACH documentation, where required, is confirmed according to the ordered materials and your documentation requirements.
