(III) Material and Style
Nyaf Earthing Wire strictly controls the selection of materials to ensure the performance and quality of the product. The conductor core is made of high-purity electrolytic copper with a purity of over 99.9%. High-purity electrolytic copper has excellent conductivity, which can reduce losses during current transmission and ensure the reliability of grounding effects. At the same time, high-purity copper also has good ductility and toughness, facilitating subsequent stranding processing.
The outer insulating sheath is available in two materials: PVC and XLPE. PVC has good insulation performance, chemical corrosion resistance, and processing performance, and is relatively economical in price, suitable for grounding scenarios in general environments. XLPE, namely cross-linked polyethylene, compared with PVC, has higher heat resistance, aging resistance, and mechanical strength, and can be used in harsher environments, such as outdoor environments with high temperature and strong ultraviolet radiation.
In terms of style, Nyaf Earthing Wire adopts a multi-strand
Stranded Conductor structure. This structure not only improves the
Flexibility of the cable, enabling it to be easily bent and laid in complex construction environments, facilitating the operation of installers, but also the multi-strand stranding can increase the surface area of the conductor, improve heat dissipation performance, reduce heat accumulation during current transmission, and ensure the safe operation of the cable. In addition, the multi-strand stranded structure can also enhance the mechanical strength of the cable, making it less likely to break when stretched and bent, and extending the service life of the cable.
The color of the cable adopts the internationally 通用的 yellow-green (Y/G) identification. This color combination has high recognition, which can intuitively distinguish it from other circuit cables, avoid misoperation during construction and maintenance, and ensure the clarity and safety of the grounding function. The yellow-green identification not only complies with global safety standards but also provides convenience for construction personnel to quickly identify and correctly wire.
(IV) Production Process
The production process of Nyaf Earthing Wire strictly follows the International Electrotechnical Commission (IEC) and national electrical standards (such as GB, UL, etc.), and adopts advanced production technology to ensure the stable and reliable quality of each batch of products.
In the conductor manufacturing process, first, high-purity electrolytic copper is smelted and cast into ingots, and then the copper ingots are processed into copper rods through a continuous extrusion process. The copper rods are drawn by a wire drawing machine to form
Copper Wires of different diameters. During the wire drawing process, the drawing speed and die size are precisely controlled to ensure that the diameter of the copper wire is uniform and the surface is smooth and free of defects.
Next is the conductor stranding process. Multiple copper wires are stranded according to a certain stranding method and pitch to form a multi-strand stranded conductor. During the stranding process, advanced stranding equipment is used to ensure that each strand of copper wire is evenly stressed and tightly stranded, avoiding looseness and wire breakage. The stranded conductor not only has good flexibility but also stable conductivity.
The extrusion process of the insulating sheath is one of the key links in the production process. The stranded conductor is fed into the extruder, and a layer of uniform PVC or XLPE insulating sheath is extruded outside the conductor. During the extrusion process, the extrusion temperature, speed, and pressure are strictly controlled to ensure that the thickness of the insulating sheath is uniform, tightly combined with the conductor, and free of bubbles, impurities, and other defects. For XLPE sheaths, cross-linking treatment is also required, and the polyethylene molecules are formed into a cross-linked structure by heating to improve the performance of the sheath.
During the production process, a series of quality inspections are also carried out on the cables. Including the detection of conductor diameter and resistance value, the detection of insulation sheath thickness, insulation resistance, and voltage resistance performance, etc. Each process has strict quality control standards to ensure that unqualified products do not enter the next process.
Finally, the finished cables are measured for length and packaged. During the packaging process, professional winding equipment is used to neatly wind the cables on the reels for easy transportation and storage. At the same time, information such as product specifications, models, lengths, and production dates is marked on the packaging to facilitate customers' identification and use.
