UL 5335 Mica Glass Braid Wire for Industrial Oven Internal Wiring
Industrial ovens route internal wiring through a thermal environment that a standard appliance-grade construction is not built to handle — sustained high heat, confined routing space, and long service intervals between equipment overhauls. UL AWM Style 5335 mica glass braid wire, rated 450°C and 600 Vac, is a construction commonly specified for this exact condition. This page focuses on the single-conductor UL 5335 construction for protected internal wiring inside industrial ovens and similar thermal-processing equipment; where a project specifically requires a multi-conductor assembly, that configuration is addressed separately.
The Confirmed UL 5335 Construction
| Parameter | UL 5335 |
|---|---|
| UL AWM Style | 5335 |
| Description | Single or Multiple Conductor with Non-Extruded Insulation |
| Temperature Rating | 450°C |
| Voltage Rating | 600 Vac |
| Conductor Size Range | 22 AWG – 4/0 AWG; solid or stranded for 22–8 AWG, stranded only above 8 AWG |
| Insulation | Mica with glass braid |
| UL-Defined Use | Internal wiring where protected from mechanical abuse |
Mica and Glass Braid Thickness by Conductor Size
UL 5335’s mica and glass braid thickness requirements change by conductor size group — a relevant detail when specifying this construction for a particular oven-wiring conductor size:
| Conductor Size | Mica (min. avg.) | Glass Braid (min. avg.) |
|---|---|---|
| 22–12 AWG | 23 mils | 5 mils |
| 11–4 AWG | 27 mils | 10 mils |
| 2 AWG–4/0 AWG | 32 mils | 15 mils |
These are the exact minimum average construction values confirmed for this Style. This page does not convert them into an invented finished conductor or cable outside diameter — conductor geometry and production tolerances are order-specific.
Protected Internal Wiring — Not a General-Purpose Lead Wire
The confirmed UL 5335 use is internal wiring where protected from mechanical abuse. This is the installation boundary this page works within: fixed internal routing inside an oven or thermal-equipment enclosure, positioned so the wire is not exposed to mechanical impact, abrasion, or crushing during normal operation, handling, or servicing. This page does not describe UL 5335 as flexible, high-flex, drag-chain suitable, or continuous-motion wiring, and does not publish a bend radius or flex-cycle rating, since none of these are established by the Style-level record.
Optional Multi-Conductor Assembly
UL Style 5335 permits two or more conductors described by the Style to be cabled together, with a maximum assembly outside diameter of 1.500 inches. The assembly may use a mica glass binder and/or fiberglass fillers, and receives an overall treated glass braid. This is an optional provision within the Style, not the primary intent of this page — for a project specifically requiring a multi-conductor UL 5335 cable assembly, that configuration is covered by a separate product page. The base construction described here is a single conductor.
Optional Metallic Shield
UL Style 5335 also permits an optional shield of 36–30 AWG strands, using Type A Nickel, 27% minimum nickel-coated copper, nickel-chromium-iron, or stainless steel 304. This shield is a separate, optional construction element from the primary conductor — this page does not state that the primary conductor material is nickel, nickel-coated copper, nickel-chromium-iron, or stainless steel on the basis of this optional shield feature. If your application requires it, specify the shield material when requesting a quotation.
600 Vac Does Not Establish Conductor Size or Current Capacity
The 600 Vac rating is a voltage rating — it does not by itself indicate the required conductor size or current-carrying capacity for your oven design. Voltage rating, conductor size, current requirement, and installation condition are separate engineering inputs. This page does not publish an ampacity figure, current rating, or generic load table; the required conductor size or electrical design requirement should be provided by the buyer based on the actual equipment design.
Industrial Oven and Thermal Equipment Internal Wiring
The confirmed UL 5335 use is internal wiring where protected from mechanical abuse. Realistic commercial contexts for this construction include industrial oven internal wiring, high-temperature internal cable routing, thermal-processing equipment internal circuits, heating systems requiring a 450°C internal wire, and OEM assemblies in extreme-heat environments. This page does not extend UL 5335 into building wire, branch circuit wiring, field wiring, external power cable, portable cord, tray cable, or general power distribution.
What UL 5335 Does Not Define for the Purchase Order
The Style data does not automatically define: conductor material, conductor plating, strand count, strand diameter, conductor resistance, ampacity, current rating, finished OD, bend radius, standard colour, MOQ, lead time, stock status, reel length, or production capacity. These must be confirmed according to your BOM and order — none of them are invented on this page.
