UL 3172 Silicone Braid Wire Products

This category collects the UL 3172 silicone braid wire products available from CableApex. UL Style 3172 is a single conductor with extruded insulation and a non-extruded covering: extruded silicone rubber at a 30 mils minimum average wall, covered by one or more glass or aramid braid fibrous coverings conforming to the same specification as Type SF-2 fixture wire. The Style is rated 200°C at 600 Vac across a conductor range of 26 AWG to 18 AWG, solid or stranded. The UL Style file states the use as internal wiring of appliances.

Note that the Style permits either glass or aramid braid, so “silicone braid wire” is the accurate category term rather than fiberglass alone. The braid type, the number of braid layers, and the conductor construction all vary between the products listed below and between individual orders. The ordered construction, the actual marking applied, and the supporting documentation must be confirmed within the applicable certified scope before an order is accepted.

UL 3172 Wire Specifications

Available UL 3172 Wire Constructions

The UL Style scope covers 26 AWG through 18 AWG in solid or stranded construction. The insulation is extruded silicone rubber at 30 mils minimum average thickness, with 27 mils minimum at any point, and the covering is one or more glass or aramid braid fibrous coverings. Both braid materials are within the Style scope, and the number of braid layers is a construction variable rather than a fixed value.

Not every combination of AWG, conductor form, braid material, braid layer count, colour and packaging format is continuously stocked. Conductor material or plating, insulation colour, finished dimensions, packaging format, wire marking and the documents supplied with a shipment must all be confirmed by quotation and order before production. Where a requested combination has not previously been produced, confirm feasibility at the enquiry stage rather than assuming availability from the Style scope alone.

The product cards below represent different ordered constructions and purchasing requirements within the same UL Style 3172 scope — they differ in conductor size focus, braid specification, and the commercial terms attached to a particular order rather than in the underlying Style rating.

For the general Style entry point covering construction, ratings and order confirmation in detail, start from UL 3172 silicone braid wire for appliance internal wiring.

Internal Wiring of Appliances

The UL Style 3172 file defines the use as internal wiring of appliances. That statement sets the boundary for how products in this category are supplied and specified.

Final suitability for any given installation is not determined by the Style rating alone. It must be evaluated against the intended equipment, the routing conditions along the full wire path, the specific ordered construction — including conductor form, braid material and layer count, and the resulting finished dimensions — and the marking required for the buyer’s own equipment evaluation. Buyers should confirm that the intended use falls within the internal wiring of appliances scope before specifying a construction from this category.

UL 3172 vs UL 3135

UL 3172 and UL 3135 are the two silicone Styles most often compared. Both are rated 200°C at 600 Vac with extruded silicone rubber insulation at 30 mils minimum average and 27 mils minimum at any point. The differences are in the conductor range and the covering.

The two Styles also differ in their stated use: UL 3135 carries the additional “where totally enclosed” condition, while UL 3172 does not. Match the Style against the actual design requirement rather than treating them as interchangeable.

The wider ranges are available under Silicone Rubber Wire and AWM Wire.
