Ningbo Richge Technology Co., Ltd., founded in 2021 in Ningbo Zhejiang, is a professional manufacturer integrating independent R&D, in-house production, technical support, brand operation, import & export and authorized premium electrical brand distribution. By consolidating years of industry resources, the company has built a well-rounded product and service system, with a sharp focus on three core sectors: high and low voltage switchgear accessories ,industrial pneumatic components, and high-voltage switching equipment. This has created a robust and integrated industrial structure that combines in-house manufacturing, proprietary branding, and premium agency distribution—offering one-stop supporting solutions to clients across power engineering, industrial automation, and high-end equipment manufacturing.
The company's core team brings over thirty years of deep expertise in high and low voltage electrical accessories and industrial automation, with roots tracing back to 1987. In 2021, the company was formally incorporated to consolidate its industrial assets and respond efficiently to the one-stop procurement needs of domestic and international customers. Today, the company operates through three main business divisions: High & Low Voltage Switchgear Accessories (core in-house operations), SOLH-brand Pneumatic Components (proprietary brand), and High-Voltage Switchgear (premium agency sales). Its product portfolio covers the full spectrum of distribution auxiliary components and industrial pneumatic parts, delivering complete supporting products and technical services to customers in power engineering, industrial automation, and high-end equipment manufacturing.
Dedicated to the R&D, manufacturing, and sales of full sets of accessories for high and low voltage switchgear, our product range fully covers major mainstream low-voltage switchgear series including MNS, GCS, GCK, R-Blokset, and R-OKKEN. Core categories include main circuit connectors, auxiliary circuit connectors, switch operating mechanisms, insulating parts, and cable connection components, with over 1,000 specifications available to suit various high and low voltage assemblies. These products are widely applied in power grids, industrial and mining facilities, building power distribution, rail transit, and more.
SOLH is our in-house pneumatic brand, established in 2002, with manufacturing based in Yueqing, Zhejiang, occupying over 1,500 square meters of standardized production space. The brand integrates independent R&D, large-scale production, and global sales. Its product line includes control components such as solenoid valves, pressure reducing valves, booster valves, and mechanical valves; actuators including standard and non-standard cylinders; as well as auxiliary components like air source processors, vacuum generators, pneumatic fittings, and filters. All series are available in complete specifications and support custom development. Key seals and solenoid coils are sourced from premium Japanese suppliers, delivering performance comparable to Japanese brands at roughly one-third the price.
We professionally distribute a full range of indoor and outdoor high-voltage vacuum circuit breakers, high-voltage load switches, high-voltage disconnectors, high-voltage earthing switches, and related accessories. All products comply with national electric power industry standards, offering customers a one-stop high-voltage electrical procurement service.
Our facility is equipped with CNC laser cutting machines, CNC press brakes, precision stamping presses, and fully automatic injection molding machines, alongside professional testing instruments for temperature rise testing, voltage detection, resistance testing, and insulation withstand voltage checks. This enables full in-house production and quality control from raw material processing to finished goods. The company holds ISO 9001 quality management system certification, with standardized management procedures covering procurement, production, inspection, and warehousing.
To deliver cost-effective products that rival imported alternatives, we use core components sourced from Japan, combined with over two decades of proprietary manufacturing expertise and precision assembly techniques. Product performance, durability, and stability are benchmarked against leading Japanese counterparts. Guided by the philosophy of "No excellence, no shipment," we continuously refine precision, service life, and adaptability across operating conditions, with regular product upgrades. SOLH has earned the trust of major domestic manufacturers including Foxconn, Huawei, Midea, and Gree, making it a preferred supplier for automation equipment manufacturers and high-end equipment makers seeking quality pneumatic components at competitive prices. Our integrated quality management system, certified to ISO 9001, ensures full traceability from raw material intake through precision machining, assembly, and final shipment.
In 2021, we established a dedicated international trade team and officially expanded overseas. Our current sales distribution is as follows:
Southeast Asia — 40%
Middle East — 30%
Europe — 20%
Other Regions — 10%
Guided by the core principles of quality first, innovation-driven, and integrity-based mutual success, we are committed to delivering high-value electrical distribution and industrial automation solutions—both products and technical services—to clients globally. We operate pragmatically and strive for steady, sustainable growth.
