UL 3666 105°C XLPE Wire for Saudi Arabia and UAE — 8 AWG Wholesale
UL 3666 is a cross-linked polyethylene insulated wire rated 105°C and 600V AC under UL AWM Style 3666. It occupies a specific position in the AWM XLPE wire range: rated 15°C higher than UL 1015 PVC (105°C vs 90°C for the standard PVC grade), and at a similar price point — making UL 3666 the value-optimised XLPE specification for buyers who need better thermal performance than PVC without the cost premium of higher-grade XLPE such as UL 3266 (125°C) or UL 3321 (150°C).
The 8 AWG size carries 40A in free air at 105°C and sits at the transition point between light control wiring and heavier motor and power wiring — it is one of the most commonly specified AWG sizes for motor lead connections on 15–22 kW LV motors, for panel internal power feeds in the 30–40A range, and for industrial cable harness assemblies across Saudi Arabia and UAE industrial, oil and gas, and infrastructure installations. Panel builders and electrical contractors in Jeddah, Riyadh, Dubai, and Abu Dhabi source 8 AWG UL 3666 XLPE wholesale directly from Chinese manufacturers CIF Jebel Ali and CIF Jeddah. CableApex manufactures UL 3666 under File No. E333030 and exports factory-direct to Saudi Arabia and UAE.

UL 3666 vs UL 1015 — Why XLPE over PVC for Saudi and UAE
| Property | UL 3666 XLPE (this product) | UL 1015 PVC |
|---|---|---|
| Temperature rating | 105°C | 105°C (standard) / 90°C (some grades) |
| Insulation type | Cross-linked polyethylene | PVC thermoplastic |
| Behaviour at high temperature | Maintains shape — cross-linked, non-softening | May soften and deform above 90°C |
| Oil resistance | Good | Moderate |
| Chemical resistance | Better — XLPE resists more solvents | Standard |
| GCC ambient suitability (8 AWG, 40A) | Better — stable insulation in 45°C+ ambient | Marginal at high ambient + high current |
| Price vs UL 1015 | Slightly higher | Lower |
| Price vs UL 3266 (125°C) | Lower — value XLPE grade | — |

Wholesale Supply to Saudi Arabia and UAE
Saudi Arabia panel builders and electrical contractors
Panel builders and electrical contractors in Jeddah, Riyadh, and the Eastern Province source UL 3666 8 AWG XLPE wire for the 40A internal power circuits in industrial control panels, motor control centres (MCCs), and electrical switchboards supplied to Saudi Aramco, SABIC, and construction projects across the Kingdom. The 105°C XLPE insulation of UL 3666 is increasingly specified over UL 1015 PVC by Saudi procurement teams that have experienced PVC wire insulation deformation in hot panel enclosures during summer — a failure mode that does not occur with XLPE insulation at equivalent temperature ratings.
UAE wholesale distributors and JAFZA manufacturers
UAE electrical wholesale distributors serving the Dubai and Abu Dhabi market, and equipment manufacturers in JAFZA and Dubai Industrial City, source 8 AWG UL 3666 XLPE wire in wholesale quantities CIF Jebel Ali for resale and production use. The combination of UL certification under File No. E333030, competitive factory-direct pricing, and 16–20 day transit from Yangzhou makes direct procurement from CableApex an efficient supply chain option for UAE buyers with sufficient volume to justify direct factory orders.
AWG Range for Saudi and UAE Applications

| 10 AWG | 5.26 mm² | 30A | 11–15 kW | Motor leads, VFD input wiring |
| 8 AWG | 8.37 mm² | 40A | 15–22 kW | Motor leads, panel power feeds — most specified |
| 6 AWG | 13.3 mm² | 55A | 22–30 kW | Larger motor leads, busbar feeds |

Common Applications
Motor lead connections (Saudi and UAE industrial)
8 AWG UL 3666 covers the 40A motor lead specification for 15–22 kW LV induction motors across Saudi Arabia’s industrial and petrochemical facilities and UAE’s manufacturing and HVAC sectors. The 105°C XLPE insulation handles standard motor terminal box ambient temperatures in air-conditioned or moderately ventilated Saudi and UAE industrial environments. For higher-ambient outdoor motor installations, see: UL 3266 125°C XLPE wire.
Control panel internal power wiring
Internal 40A power feeds inside UL 508A control panels supplied to Saudi Aramco, SABIC, and UAE construction and infrastructure projects — VFD input power connections, transformer feeds, and busbar leads in the 30–40A circuit range where 8 AWG provides adequate cross-section at 105°C.
OEM equipment wiring harnesses
Equipment manufacturers in Dubai and Riyadh assembling industrial machinery and electrical equipment for the GCC market use 8 AWG UL 3666 XLPE in production wiring harnesses where UL certification under File No. E333030 is required by the end-user’s procurement specification.
Other applications
- HVAC equipment motor leads in air-conditioned machine rooms
- Generator set internal control and power wiring
- Solar inverter internal AC wiring in GCC installations
- Data centre UPS internal power distribution wiring
