UL 3135 600V Silicone Wire for Dubai and UAE Enclosed Equipment
UL 3135 silicone rubber wire is rated 200°C and 600V AC under UL AWM Style 3135 — the standard high temperature internal wiring specification for enclosed electrical equipment where the wire must withstand sustained elevated temperatures generated by the equipment itself rather than an external heat source. The 200°C rating of UL 3135 silicone rubber insulation is achieved through the inherent thermal stability of the silicone polymer chain, which maintains its elastic, non-brittle physical form and its electrical insulation properties continuously at temperatures where XLPE and PVC insulation would soften, deform, or begin thermal degradation.
The keyword “enclosed wire” in the context of UL 3135 refers to the application category: UL AWM Style 3135 is specifically recognised for use as internal wiring within enclosed electrical equipment — appliances, industrial machines, control panels, transformers, and motors — where the wire is not directly exposed to external environmental conditions but must withstand the internal thermal environment of the equipment enclosure. In Dubai and UAE’s industrial and commercial sectors, where ambient temperatures of 40–50°C in summer significantly raise the internal temperatures of electrical enclosures beyond what XLPE or PVC wire can reliably handle over a 10–20 year equipment life, UL 3135 silicone rubber wire is the specification of choice for equipment builders and maintenance operations sourcing UL-certified high temperature internal wire. CableApex manufactures UL 3135 under File No. E333030 and exports factory-direct CIF Jebel Ali to Dubai and across the UAE.

Dubai and UAE Enclosed Equipment Applications
Commercial oven and food equipment internal wiring (Dubai)
Dubai’s hospitality and food service sector operates one of the world’s densest concentrations of commercial kitchen equipment. Combination ovens, deck ovens, and proofing cabinets used in Dubai hotels and restaurant kitchens require UL 3135 silicone wire for internal wiring in the heated chamber zone, where temperatures of 150–250°C at the wire surface are sustained during continuous operation. UL 3135’s 200°C rating covers the full operating temperature range of commercial catering ovens, and the silicone insulation’s physical stability at these temperatures ensures wire integrity throughout the appliance service life without the charring or insulation cracking that occurs with PVC or XLPE wire in the same zone.
Industrial heating equipment internal wiring (UAE)
Industrial heating ovens, curing chambers, heat treatment furnaces, and infrared heating equipment installed in UAE manufacturing facilities require UL 3135 for internal wiring in the heated zone. Equipment OEMs supplying the UAE industrial market from Dubai Industrial City and JAFZA specify UL 3135 for any internal wire routing where the sustained operating temperature of the equipment exceeds the 125°C limit of XLPE wire.
Motor lead connections in hot enclosures
LV motors installed inside heated equipment enclosures — oven drive motors, conveyor motors in heated tunnels, and pump motors in hot process environments — require UL 3135 silicone rubber for the motor lead wire connecting the terminal block to the external cable connection point. The motor’s own heat combined with the elevated enclosure ambient temperature can exceed 150°C at the motor terminal connection, requiring 200°C silicone insulation. See also: UL 3266 125°C XLPE motor lead wire for standard ambient motor connections.
Transformer internal connections
Dry-type transformer manufacturers and rewinding shops in Dubai supplying UAE industrial and commercial projects specify UL 3135 for the internal lead connections from the transformer winding to the terminal board — where the wire must withstand the combined heat of copper loss and iron loss in the transformer core over the full transformer service life at rated load.
Available AWG Sizes — Dubai and UAE Procurement
| AWG | Cross-section | Typical application |
|---|---|---|
| 22–18 AWG | 0.325–0.823 mm² | Sensor leads, thermocouple connections, control wiring in hot zones |
| 16–14 AWG | 1.31–2.08 mm² | Heating element connections, small motor leads |
| 12–10 AWG | 3.31–5.26 mm² | Motor leads, transformer connections, panel power feeds |
| 8–6 AWG | 8.37–13.3 mm² | Large motor leads, industrial oven heating circuit connections |
