Single-Core Wire Harness with Green Serrated O-Type Ring Ground Terminal

Customized single-core wire harness specifically designed for reliable equipment grounding protection, terminated with a green serrated O-type ring ground terminal. It is widely used in household appliances, industrial equipment, distribution boxes, switchgear cabinets, new energy equipment, and various electrical systems with explicit grounding safety compliance requirements. Within electrical safety standards, green (typically paired with a yellow stripe) is internationally designated as the standard identification color for ground wires. Both the terminal and the harness sheath of this product are strictly manufactured in standard green, allowing installation and maintenance personnel to quickly and accurately identify grounding lines within complex wire systems, avoiding wire or maintenance errors caused by color confusion, and fully complying with relevant electrical safety standards and industry conventions.
The terminal body features a serrated ring design, with fine tooth-like ridges machined into the surface that contacts the connected metal component. Compared with plain, smooth ring terminals, this design offers markedly better anti-slip and bite performance: when the terminal is fastened to an equipment housing, ground bar, or grounding stud with a bolt and nut, the serrated ridges effectively bite through any oxide layer, paint coating, or light oxidation film that may exist on the connected metal surface, establishing a tighter, more reliable direct metal-to-metal contact. This significantly reduces contact resistance, fully ensuring the low-impedance characteristics and conductivity required of a grounding circuit. The serrated structure also effectively prevents the terminal from rotating or shifting due to vibration or loosening over long-term use, further improving the long-term stability and reliability of the ground connection — particularly suited for industrial equipment, power cabinets, and outdoor installations where grounding reliability is critical.
The terminal is stamped from high-quality copper alloy and surface-treated with tin or nickel plating, offering excellent conductivity and corrosion resistance, able to withstand humid, dusty, and otherwise demanding environments over the long term without oxidation or rust. The single-core wire is manufactured from high-quality copper core conductors, with cross-sectional area selectable according to the customer's actual grounding current and current-carrying requirements, wrapped in a wear-resistant, aging-resistant, and flame-retardant green insulation sheath, giving the entire harness a consistent color and clear identification. We support customization of conductor wire gauge, overall harness length, terminal ring bore diameter (to match different grounding bolt sizes), and specific terminal dimensions according to each customer's device interface standards. During production, we strictly implement continuity testing, tensile strength testing, terminal crimp strength testing, and visual inspection as part of a multi-layered quality control process, ensuring every harness meets relevant industry standards before shipment — providing customers with a safe, reliable, and clearly identified customized grounding harness solution, serving industries such as appliance manufacturing, industrial automation, new energy, and power equipment.
