Package
UL3239 Wire 14AWG Silicone Rubber Insulated Wire Packaging
Every shipment of UL3239 14AWG silicone rubber insulated wire from Dongguan Great Wire & Cable Co., Ltd. is meticulously packaged for safe transport and convenient handling. After production and quality inspection, the wires are neatly wound onto reels or spools and secured with protective packaging to prevent entanglement, moisture, and dust. For larger orders, we package multiple reels into sturdy cartons or wooden boxes, clearly labeled with specifications, lengths, and batch information. This systematic packaging ensures that every shipment arrives intact, organized, and ready for immediate use.
Production Line
At Dongguan Greater Wire & Cable Co., Ltd., the production of UL3239 14AWG Silicone Rubber Insulated Wire takes place on a highly automated and meticulously monitored line. The process begins with high-purity copper conductor drawing and precise stranding, ensuring consistent conductivity and flexibility. Advanced silicone extrusion systems then cover the conductor with uniform insulation that withstands extreme temperatures and mechanical stress. The cables pass through inline quality inspection equipment, which monitors diameter, insulation thickness, and surface integrity in real time. Finally, each batch undergoes rigorous electrical and mechanical testing, including voltage resistance, tensile strength, and flame-retardant performance, guaranteeing that every cable leaving the factory meets international standards and client specifications.
Strict Quality Tracking
Every cable is fully documented and tracked from raw material procurement to finished product shipment, ensuring traceability and consistency.
