UL AWM Style 5476 Mica Tape Glass Braid Wire for Vietnam and Indonesia Sourcing
This page is the regional sourcing page for UL AWM Style 5476 mica tape and glass braid internal wire for buyers in Vietnam and Indonesia. It covers the verified Style scope of 30 AWG–4/0 AWG and is written for procurement teams, distributors and equipment OEM buyers whose drawing, existing wire specification or approved BOM calls for Style 5476.
Style 5476 is described in the Style record as a single or multiple conductor with other-than-extruded insulation. The construction is mica tape with glass braid, rated 450°C and 600 Vac, with a Horizontal Flame designation. The mica tape and the treated glass braid each carry minimum average thickness requirements that change with conductor size, and the Style also permits an optional binder, an optional shield and an optional cabled multi-conductor assembly.
The official Use carries three limitations that shape how this wire is specified: no repeated flexing, protection from mechanical abuse, and acceptability including current-carrying capacity determined by UL, LLC. Those limitations are treated here as part of the specification rather than as small print.

Ten points to clarify about the tables above:
- The verified temperature rating is 450°C. No duty or service-duration qualifier is attached to it in the record.
- 600 Vac is the verified voltage rating. No DC rating appears in the record.
- Mica tape with glass braid is one construction definition, and the braid treatment is silicone varnish or TFE finish. The treatment is a braid finish, not the primary insulation identity.
- All six construction values are minimum average thickness requirements. The record states no minimum-at-any-point value for this Style, and none is supplied here.
- The thickness groups are size-dependent. Values from one group do not apply to another.
- The binder, the shield and the cabled assembly are separate optional provisions, each included only where specified and confirmed.
- The optional 36–30 AWG Type “A” Nickel or 27 percent minimum nickel coated copper item belongs to the shield provision. It is not the main conductor specification.
- Conductor material, plating, strand count, strand diameter and lay length are not defined by the Style.
- Finished OD, OD tolerance, conductor resistance, minimum bend radius and ampacity are not Style-level values.
- 30 AWG–4/0 AWG is the Style scope, not an inventory list or a guarantee that every size and optional configuration is available.
The 450°C and 600 Vac Ratings
The Style rating is 450°C, written without a service-duration qualifier. This page does not describe it as continuous, sustained or continuous-duty, and it derives no service life, thermal cycling count or thermal margin from it.
A 450°C rating is also not a fire-survival or circuit-integrity property. Style 5476 is not presented as fire-resistant cable, fire alarm cable or circuit integrity cable, and the flame designation in the record is Horizontal Flame. VW-1, FT1 and vertical flame designations are not part of this Style record and are not claimed.
The voltage rating is 600 Vac. It is not written as 600 Vdc, as an AC/DC rating, or as a 600/750 V rating.
Mica Tape with Glass Braid in Three Size Groups
The construction requirement splits into three conductor-size groups. For 30–12 AWG, total mica tape layers must meet 17 mils minimum average and the treated glass braid 7 mils minimum average. For 11–4 AWG the figures are 21 mils and 15 mils. For 3–4/0 AWG they are 26 mils and 20 mils.
Two points matter in procurement. First, every one of these is a minimum average value. The record gives no minimum-at-any-point requirement for Style 5476, so quoting one would add a requirement the Style does not contain. Second, the values belong to their groups. A specification that carries the 17/7 mil figures across the whole 30 AWG–4/0 AWG range has applied one group’s values outside their range.
The glass braid is treated with silicone varnish or TFE finish. Those are braid treatments and are not described here as silicone insulation, PTFE insulation or a TFE primary insulation system. The Style is defined as other-than-extruded insulation, and neither the mica tape nor the braid alone constitutes the whole construction.
The record also does not assign a purpose to the braid. This page therefore does not describe the braid as outer mechanical protection, because the official Use separately requires the installed wiring to be protected from mechanical abuse. The presence of a braid does not remove that requirement.
Optional Binder, Optional Shield and Optional Cabled Assembly
Three optional provisions appear in the Style record, and each stays optional here.
Binder. A binder may be applied between the mica tape and the glass braid. The record refers to the facing page for material detail, so the binder material, its thickness and any function are confirmed from the qualified construction rather than stated on this page.
Shield. An optional shield of 36–30 AWG Type “A” Nickel or 27 percent minimum nickel coated copper is permitted. This is a shield provision. It does not establish the main conductor material, and it is not a recommendation for conductor plating at any temperature.
Cabled assembly. Two or more conductors described by the Style may be cabled together, with a maximum overall diameter of 1.500 inches where this provision applies. A mica glass binder and/or fiberglass fillers may be employed, and the assembly may have an overall treated glass braid. None of these elements is automatic: the number of conductors, the use of fillers and the presence of an overall braid are all configuration-dependent and specified in the RFQ. This page primarily represents single-conductor wire sourcing, and the assembly provision is disclosed here as Style scope.
Conductor: Form Defined, Material Open
The Style defines the conductor range as 30 AWG–4/0 AWG, solid or stranded. It does not define the conductor material or finish, so nickel-plated copper, bare copper, tinned copper, silver-plated copper and nickel conductors are all constructions that a buyer may specify rather than properties this page can assert.
The following are RFQ fields:
- solid or stranded form
- main conductor material
- plating or surface finish
- strand count, strand diameter and lay construction, where controlled
- maximum conductor resistance, where controlled
Stranding classes and flexibility grades are not part of the record and are not applied to Style 5476 here.
Finished Diameter Is Not a Style Value
The Style record publishes minimum average thicknesses for the mica tape layers and the treated glass braid. It does not publish a finished outer diameter for single-conductor wire, a maximum OD, an OD tolerance, or any dimensional comparison with another Style.
Minimum layer thickness and finished wire diameter are different quantities. Actual finished OD depends on the actual conductor construction and diameter, how the mica tape is applied, the braid construction, whether the optional binder is used, whether the optional shield is used, and manufacturing dimensions. A lower minimum thickness requirement in one Style therefore does not establish that a finished wire will be smaller than a wire built to another Style at the same conductor size, and no such claim is made on this page.
Where routing clearance controls the purchase, the way to resolve it is dimensional, not comparative. Buyers should state the required AWG, the maximum finished OD, the OD tolerance, the available routing clearance or opening dimensions, and the dimensions of any wire currently installed. The proposed construction is then checked against those figures. Fit through an existing opening is never promised on the basis of Style designation alone, and no minimum bend radius is published here, since the record contains none.
Official Use and Its Three Limitations
The official Use is “Internal wiring where not subjected to repeated flexing and protected from mechanical abuse, and where the acceptability, including current-carrying capacity, has been determined by UL, LLC.”
Repeated flexing is excluded. Style 5476 is not presented for repeated flexing, continuous movement, cable carriers, drag chains, hinged routes, moving equipment doors or robotic motion.
Protection from mechanical abuse is required. The wire is not presented for exposed abrasive routing, unprotected machinery runs, external field cable, or positions subject to impact or repeated rubbing. Protection at the routing position is part of the equipment design.
Acceptability, including current-carrying capacity, is determined by UL, LLC. This page therefore publishes no ampacity table and derives no current value from conductor size, the 450°C rating or the 600 Vac rating. Conductor sizes are not labelled high-current, high-power or heater-lead sizes.
The Use is also not extended to building or field wiring, external equipment wiring or portable cord. High-temperature equipment such as furnaces, kilns, ovens and heat treatment equipment may be the buyer’s context, but this page does not present Style 5476 as furnace wire, kiln wire, heating-element lead wire or thermocouple wire. Thermocouple extension and compensation characteristics are not established by this Style record at all. The controlling requirements remain the customer’s approved equipment specification, the Style Use limitations and the proposed qualified construction.
Vietnam and Indonesia Sourcing Context
Vietnam and Indonesia are the commercial setting for this page: buyer locations, OEM sourcing markets, industrial equipment procurement markets, component distribution markets and shipment destinations. Enquiries typically come from buyers requesting Style 5476 by AWG, from buyers supplying an existing wire specification or drawing, from buyers who need a single-conductor or an optional multi-conductor construction, and from buyers who control a maximum finished OD.
No regional usage practices, end-user industries or named projects are claimed for either market. Destination city or port, Incoterm, packaging and quantity are quotation variables handled per enquiry rather than published as fixed terms.
Bulk Wire Versus Processed Leads
This page represents Style 5476 wire supplied as bulk wire. Supply does not automatically include cutting, stripping, crimping, terminals, connectors, ceramic beads or bushings, finished leads or assemblies. Any processing requirement must be specified separately with lengths, termination details and drawings.
What Style 5476 Does and Does Not Define
Style 5476 defines:
- 450°C temperature rating and 600 Vac voltage rating
- Horizontal Flame
- conductor range 30 AWG–4/0 AWG, solid or stranded
- mica tape with glass braid, the braid treated with silicone varnish or TFE finish
- minimum average mica tape thickness of 17, 21 and 26 mils by size group
- minimum average treated glass braid thickness of 7, 15 and 20 mils by size group
- an optional binder between mica tape and glass braid
- an optional cabled multi-conductor assembly to a maximum overall diameter of 1.500 inches
- an optional shield provision
- Marking: General
- the Use limitations on repeated flexing, mechanical abuse and acceptability including current-carrying capacity
Style 5476 does not universally define:
- main conductor material, plating, strand count, strand diameter or lay length
- finished OD, OD tolerance or minimum bend radius
- conductor resistance, ampacity or current rating
- conduit, opening or clearance dimensions of any equipment
- furnace, kiln, heater-lead or thermocouple suitability
- interchangeability with any other mica Style
- colour or identification, reel length, MOQ, stock, lead time, production capacity or shipping term
Common Procurement Errors
- Writing “450°C continuous” or otherwise adding a duty qualifier to the rating.
- Assuming the main conductor is nickel-plated copper.
- Reading the optional shield provision as the main conductor specification.
- Treating all Style 5476 wire as stranded.
- Quoting a minimum-at-any-point value that the record does not contain.
- Applying one size group’s mica or braid thickness across the whole range.
- Describing the braid treatment as the primary insulation.
- Publishing a universal finished OD, or assuming a lower minimum thickness produces a smaller finished wire.
- Promising fit through an existing opening without an actual product OD.
- Inventing a minimum bend radius.
- Deriving ampacity from conductor size.
- Treating the 450°C rating as fire-survival performance.
- Using the wire where it is subjected to repeated flexing.
- Relying on the braid instead of protecting the wire from mechanical abuse.
- Assuming Style 5476 can replace another mica Style because the temperature and voltage ratings match.
- Assuming every size and optional configuration is stocked.
