Multi-Core Silicone Rubber Cable Overview
This page covers multi-core silicone rubber cable assembled from multiple individually insulated silicone conductors, supplied by CableApex as a factory-direct manufacturer for high-temperature internal wiring applications. Where the ordered construction calls for it, the individual conductors within the assembly can be supplied as qualifying UL AWM Style 3135 silicone-insulated core wires. This page distinguishes clearly between the qualifying individual core wire and the completed multi-core cable assembly, since UL recognition applies at the single-conductor core level and does not automatically extend to the finished multi-conductor cable.
Core count, conductor material and finish, core colours, and overall assembly construction are confirmed according to your ordered specification.
Silicone-Insulated Multi-Conductor Construction
A multi-core silicone rubber cable is built from two or more individually insulated silicone conductors, cabled together according to the buyer’s project requirement. Required core count is not fixed by any single specification and is confirmed during quotation — this page does not present preset 2-core, 3-core, 4-core, or other fixed configurations. Similarly, the supplied UL Style 3135 record does not define an overall cable structure: it does not establish an overall sheath, silicone outer jacket, fillers, binder tape, braided covering, or shield for a multi-conductor assembly. If your project requires an overall jacket, filler, braid, shield, or other assembly element, this is confirmed according to the ordered cable specification rather than assumed as a standard feature.
UL 3135 200°C 600V Core Wire Options
26–12 AWG Solid or Stranded Core Range
Where qualifying UL AWM Style 3135 core wires are specified for the assembly, the Style covers a conductor range of 26 AWG through 12 AWG, solid or stranded. This range applies to the individual UL 3135 core option — it does not by itself define the range of every custom core that might be used in a multi-core assembly outside the Style. Conductor material and finish are not established by the Style record and are confirmed according to your ordered specification.
Silicone Rubber Insulation Construction
Qualifying UL 3135 core wires use extruded silicone rubber insulation, applied at a minimum average thickness of 30 mils and a minimum thickness of 27 mils at any point, rated 200°C and 600 Vac, with a Horizontal Flame rating. These ratings and this flame requirement apply to the qualifying individual core wire specifically. We do not describe the completed multi-core assembly as super-flexible, ultra-flexible, continuous-flex, or suitable for drag-chain or robotic applications, as no such data is established by the Style-level record — silicone rubber is described here only as a material, not as a quantified flexibility claim.
Individual UL Core Recognition vs Complete Cable Assembly
This distinction matters for both procurement and compliance. UL AWM Style 3135 is a single-conductor construction — it is not a multiple-conductor UL Style. A multi-core cable assembled using qualifying UL 3135 core wires is not, by that fact alone, a “UL 3135 multi-core cable” or a “UL-certified multi-core assembly.” The UL recognition and the 200°C / 600 Vac rating belong to each qualifying individual core wire. The completed multi-core cable’s applicable rating, marking, and documentation depend on the final ordered assembly construction as a whole, and should be confirmed separately from the core-wire specification.
Custom Multi-Core Assembly Requirements
Because the overall assembly is order-specific, useful information to confirm includes whether an overall sheath or jacket is required, whether a binder, filler, braid, or shield is needed, and what the target finished cable outside diameter should be, if applicable. None of these elements are established by the UL 3135 core-wire record, and none are assumed as standard on this page. Conductor material, plating, strand count, and resistance for both the core wires and the overall assembly are confirmed according to the ordered construction rather than published as generic figures.
Enclosed Appliance Internal Wiring Applications
Where UL 3135 core wires are used, their UL-supported use is internal wiring of appliances where totally enclosed. Appropriate application language for this page includes totally enclosed appliance internal wiring and protected internal multi-conductor connections inside appliances. This page does not position the product as building wire, field wiring, branch-circuit cable, tray cable, outdoor or direct-burial cable, or as a cable for EV, energy-storage, or solar power applications — the previous positioning around energy-storage and battery-system DC connections does not apply to this product page.
Ordering a Multi-Core Silicone Cable
To provide an accurate quotation for a multi-core silicone rubber cable, please specify:
- Number of conductors / cores required
- Required core AWG size
- Conductor material and finish
- Solid or stranded requirement
- Whether UL 3135-recognized core wires are required
- Required core colours
- Required overall assembly construction (sheath, binder, filler, braid, shield, if any)
- Target finished cable outside diameter, if applicable
- Order quantity
- Packaging requirement
- UL marking requirement, if applicable
- Documentation requirements, including RoHS / REACH if needed
- Shipping destination
Send this information and we respond with a quotation within 12 business hours. Production lead time depends on the confirmed construction and order quantity, and shipping options and applicable Incoterms are confirmed during quotation according to destination.
UL Marking and Documentation
Qualifying UL AWM Style 3135 core wires 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 core construction ordered, and — as noted above — do not automatically extend to the completed multi-core assembly. Not every configuration automatically carries a UL Mark, and marking requirements should be confirmed when requesting a quotation. RoHS and REACH are separate regulatory frameworks from UL recognition; applicable RoHS / REACH documentation requirements can be confirmed according to the ordered construction.
This product supports our Multi-core Cable range. For details on the qualifying single-conductor core option, see our UL 3135 Silicone Wire category.
