1. Bare Wire and Bare Conductor Products
The main characteristics of this category of products are: pure conductor metal, without insulation or sheathing, such as steel-core aluminum stranded wire, copper-aluminum busbars, and electric locomotive wires. Processing techniques primarily involve pressure working, such as smelting, rolling, drawing, and stranding/compressed stranding. These products are primarily used in suburban and rural areas, user main lines, and switchgear.
2. Power Cables
The main characteristics of this category of products are: an insulation layer extruded (wound) around the conductor, such as in overhead insulated cables; a stranded structure of several cores (corresponding to the phase, neutral, and ground wires of a power system), such as in overhead insulated cables with two or more cores; or an additional sheath, such as in plastic/rubber sheathed wire and cable. The main processing technologies used include drawing, stranding, insulation extrusion (wrapping), cabling, armoring, and sheath extrusion. The process combinations used vary significantly for each product.
3. Electrical Equipment Wire and Cable
This category of products is characterized by a wide variety of specifications and applications, with voltages primarily operating at 1 kV and below. New products are constantly being developed for specialized applications, including fire-resistant cables, flame-retardant cables, low-smoke zero-halogen/low-smoke low-halogen cables, termite-proof and rodent-proof cables, oil-resistant, cold-resistant, heat-resistant, and wear-resistant cables, cables for medical, agricultural, and mining applications, and thin-walled wires.
4. Communication Cables and Optical Fiber (Brief Introduction)
With the rapid development of the communications industry over the past two decades, product development has also been astonishingly rapid. From simple telephone and telegraph cables to cables with thousands of pairs of voice, coaxial, optical, and data cables, and even combination communication cables, these products typically have small, uniform dimensions and require high manufacturing precision.
5. Magnet Wire (Winding Wire)
This category is primarily used in various motors, instruments, and meters.
