On February 2, 2026, a breakthrough was achieved in the field of high-performance ablation-resistant graphene copper-tungsten arc contacts, injecting new momentum into the UHV power grid and high-end power equipment sectors. Through multi-component graphene modification, this technology has led to the development of a new type of copper-based arc contact product. Compared with traditional contacts, its electrical conductivity and ablation resistance have both improved by more than 20%, and its hardness has increased by over 8%. The new contacts can withstand high-temperature electric arcs up to 12,000°C, with key performance reaching internationally advanced levels and breaking foreign technological monopolies. This represents an important milestone in the independent innovation of high-end electrical materials in China.
The significance of this breakthrough extends far beyond a single product improvement. By providing a more reliable "guardian" for UHV power grids, this new contact material sets a higher performance benchmark for the entire industry. It demonstrates what is achievable when advanced materials science is applied to contact design, and provides an important reference direction for the technological iteration of related products, including one-piece solid copper contacts.
As new power systems accelerate their development, high-voltage and UHV power grids have put forward increasingly strict requirements for contact materials in terms of ablation resistance, electrical conductivity, and mechanical strength. Simultaneously, the low-voltage electrical and industrial automation sectors have raised their standards for the precision, stability, and adaptability of copper-based contacts. As basic conductive components of electrical circuits, the material purity, machining accuracy, and surface quality of solid copper contact pins directly affect conduction efficiency and long-term operational reliability, making them one of the core foundations supporting the high-quality development of power equipment.
Against this industrial trend, Xiamen Apollo Electric Co., Ltd. has deeply rooted itself in the field of one-piece solid copper contacts. Focusing on conductive requirements across multiple scenarios-including high-voltage switches, low-voltage electrical appliances, and industrial control-the company provides the industry with high-quality pure copper and copper-alloy integral copper contact rivets. Relying on mature precision machining and forming processes, the company strictly controls dimensional tolerance, material purity, and surface quality to adapt to application requirements with different current loads, switching frequencies, and working conditions.
To meet the industry's demand for high reliability and precision, Xiamen Apollo Electric Co., Ltd. has carried out targeted optimizations inspired by the graphene copper-tungsten breakthrough. In material selection, high-purity oxygen-free copper and copper alloys are adopted to ensure excellent electrical conductivity and mechanical strength, satisfying stable conduction under high current loads. In processing technology, precision cold heading and CNC machining are applied to control contact dimensional tolerance within ±0.01 mm, ensuring batch consistency and installation adaptability. In surface treatment, polishing, tin plating, and other processes are used to reduce contact resistance, enhance corrosion resistance and oxidation resistance, and extend service life under complex working conditions.
Today, one-piece solid copper contacts from Xiamen Apollo Electric Co., Ltd. have been widely adopted in core equipment including high-voltage switches, low-voltage circuit breakers, contactors, and relays. By providing stable and efficient core conductive component support for downstream complete equipment manufacturers, the company helps power equipment achieve performance upgrades and quality breakthroughs. Looking ahead, with continuous iteration of copper-based contact material technologies-including advances like the graphene copper-tungsten breakthrough-Xiamen Apollo Electric Co., Ltd. will continue to deepen technological innovation in solid copper contact studs, optimize product performance and delivery efficiency, and provide solid support for the construction of new power systems and the development of high-end power equipment.
