Greater Wire's cables have been UL certified. During the production process, we carry out systematic management and strict implementation in terms of material selection, production process, testing and verification, and quality control to ensure that the cables meet UL certification. We will use raw materials that meet UL requirements, such as conductor copper materials that meet ASTM or IEC standards, insulation materials with good heat resistance, flame retardancy, and oil resistance (such as PVC, XLPE), and sheath materials with UV resistance and wear resistance. During the production process, the materials, processes, and certifications are consistent, and the products will carry the UL logo.

Solar System

Greater Wire provides UL certified THWN-2, XHHW, ground wire and PV system auxiliary cables suitable for solar environment, with excellent UV resistance, high temperature resistance and aging resistance. Our UL4703 series cables have served many large photovoltaic sites in North America and Latin America.

Farm

Greater Wire provides UF-B direct buried cables can be used for irrigation pump power, THWN-2 cables can be used for greenhouse lighting, and MTW cables can be used for automation equipment. UL series cables can be used in soil, moisture and sunlight exposure environments to maintain farm stability and reduce subsequent maintenance costs.

Ports and Docks

UL certificated TC-ER Cable, XHHW Cable, ground wire and other cables have excellent corrosion resistance, moisture resistance and UV resistance. They can be used in high salt fog areas such as coastal ports, container yards, crane systems, etc. The power system in the port area can operate stably and uninterruptedly throughout the year.

Hospital

MC Cable, THHN/THWN-2, TC-ER Tray Cable and other cables can provide a one-stop solution for main power supply, emergency power supply and backup lines. Hospitals are a scene with extremely high requirements for power continuity. UL certificated cables can ensure continuous operation in such important places without worries.

Tunnels and Tracks

UF-B direct buried cable can be used for lighting and signal, XHHW cable for trunk line, Bare Copper ground wire for grounding system, UL standard wire, support long-term stable operation in wet and closed underground environment.

Airport

TC-ER Cable, THW Cable and other cables can be used for main power supply, control signal and grounding system. UL certified wires are shielded against interference, resistant to high temperature, oil and moisture, suitable for extreme climates, and have served multiple international airport projects.

Hotels

NM-B, MC Cable, THHN Wire and other cables are used for indoor lighting and socket loops, covering all aspects of hotel wiring. UL-certified wires meet the complex power distribution needs of high-rise buildings.

Automation Equipment

MTW cables, TFFN cables, TF cables and other wires and cables are widely used in PLC control cabinets, robotic arms, and internal wiring of industrial equipment. UL certified cables are flexible and wear-resistant, suitable for factory automation upgrades.

Commercial Buildings

Building wire is suitable for commercial buildings such as national chain stores, shopping centers, and catering brands. The use of UL certified wires is conducive to fast on-site construction, fast acceptance, and stable operation.

UL cables must meet the strict requirements of UL standards for safety, performance and consistency. The manufacturing process of UL cables must be strictly and systematically controlled.

Greater Wire is a professional UL wire manufacturer focusing on R&D, manufacturing and global sales. With more than 30 years of industry experience, it continues to provide high-performance, compliant and reliable cable solutions for various engineering projects and electrical systems.

In terms of products, we cover a variety of mainstream UL certified wire categories, including MC Cable, NM-B, THHN, THWN, XHHW, UF-B, TC-ER, Bare Copper, MTW, TFFN, etc. Our cables are widely used in building wiring, industrial equipment, machinery manufacturing, infrastructure construction, energy systems, traffic signals, control systems, and other fields, fully meeting the increasingly diverse application needs of markets such as North America, South America, and Latin America.

In terms of manufacturing capabilities, Greater Wire has a fully equipped modern production line, including precision extrusion equipment, high-speed stranding machines, cabling machines, armoring equipment, laser coding systems, automatic metering, and winding packaging lines. The factory is highly automated, effectively improving efficiency and consistency. At the same time, we are equipped with high-standard testing and experimental equipment, such as high-voltage withstand voltage testers, conduction and resistance testers, insulation resistance meters, and combustion test devices.

We strictly follow the operating specifications of the UL certification system. All cable products use conductors, insulation, sheaths, and filling materials that meet UL standards. They have clear and effective UL certification marks and traceability numbers to ensure compliance, performance stability, and long-term safety. We have successfully served hundreds of industrial and civil projects in the Americas and have won a good customer reputation and market feedback.

First, choose UL certified wires, which is the basic bottom line to ensure electrical safety. Secondly, the installation of all wires and cables should be completed by qualified professional electricians and strictly follow the NEC (National Electrical Code) or CEC (Canadian Electrical Code) and the regulatory requirements of the region.

In terms of selection, the cable type should be accurately selected according to factors such as the application environment, voltage level, temperature range and laying method. For example, NM-B cables should not be used outdoors or in humid environments, or THHN cables that are limited to dry environments should be mistakenly used for underground laying. At the same time, during the wiring process, it is necessary to ensure that the stripping length is appropriate and matching connectors (such as crimping noses, wiring caps or terminals) are used to ensure that the joints are firm, the conduction is good, and the insulation is restored. Especially when using aluminum conductors, special connectors and anti-oxidation pastes are required to avoid connection problems.

Avoid overload use, correctly select the cable diameter according to the current-carrying table, and configure appropriate circuit breakers or fuses to ensure that the power supply can be cut off in time in case of overcurrent to prevent fire. For old lines, regular inspections should also be carried out, focusing on checking for potential risks such as insulation aging, damage, signs of overheating or rodent bites.

Greater Wire offers a variety of packaging options, including reel packaging, wooden shaft packaging, and pallet packaging, suitable for a variety of specifications from light wiring cables to heavy industrial cables. All packaging methods meet the practicality and safety requirements for export transportation and on-site use, ensuring that the cables are not damaged during handling and use. Of course, we support personalized packaging and customized packaging services.
