As a specialist deeply rooted in the field of lightning protection safety—and with two decades of industry expertise—Anhui Jinli has launched a comprehensive product portfolio grounded in professional technology and guided by market demand. Featuring a full range of offerings—including power, signal, photovoltaic, and energy storage SPDs—and complemented by standardized grounding resistance monitoring and installation services, the company has engineered electrical safety solutions characterized by "total scenario coverage and end-to-end protection," thereby safeguarding the safe and stable operation of enterprises across all sectors.

Power SPD: The Core of Power Protection—Safeguarding the Energy Inlet

Anhui Jinli Power SPDs cover a comprehensive range of AC and DC specifications. Designed to meet the classification requirements of Lightning Protection Zones (LPZ), they are adaptable to Level I, II, and III protection scenarios. Whether deployed at a building's main distribution board, a sub-distribution cabinet, or the power input of industrial equipment, these devices respond rapidly to clamp transient overvoltages within the tolerance limits of the connected equipment. Simultaneously, they efficiently discharge surge currents—preventing surges from propagating along power lines—thereby safeguarding the safety and stability of both the power distribution system and the connected devices, and effectively eliminating electrical safety hazards at the source.

Signal SPD: The Pioneer of Low-Voltage Protection—Ensuring Stable and Uninterrupted Transmission

With the advancement of intelligent and digital technologies, low-voltage systems—encompassing networking, surveillance, control, and communication—have become increasingly ubiquitous. However, the signal lines within these systems are highly susceptible to surges and electrostatic interference; should they sustain damage, the consequences can range from signal interruptions and equipment malfunctions to data loss and complete system paralysis. Anhui Jinli Signal SPDs are designed to be compatible with a wide array of low-voltage lines—including RJ45 network, RS485, coaxial video, and control signal circuits. Utilizing premium core components such as TVS diodes, these devices feature rapid response times and low residual voltage. They effectively suppress surges and electromagnetic interference without compromising signal transmission quality. Widely deployed in environments such as data centers, surveillance control rooms, and industrial automation systems, these SPDs safeguard the stable operation of low-voltage infrastructure and ensure the secure and seamless flow of information.

PV/Energy Storage SPDs: Empowering New Energy and Safeguarding the Efficient Development of the Solar-Storage Industry

Photovoltaic and energy storage power stations are typically situated in open outdoor environments, where they are constantly exposed to threats such as lightning strikes, operational overvoltages, and electromagnetic interference. Should protection measures fail, critical equipment—including PV modules, inverters, PCS units, and battery clusters—is highly susceptible to damage, directly compromising power generation efficiency, energy storage safety, and overall system longevity. Focusing on the specific requirements of integrated PV-plus-storage scenarios, Anhui Jinli has introduced a comprehensive solution package featuring specialized SPDs for both photovoltaic and energy storage applications. Adhering strictly to standards such as the GB/T 18802 series, this solution covers the full spectrum of DC and AC voltage levels and protection classifications, thereby establishing a complete, end-to-end surge protection system for PV and energy storage power stations—from the source to the terminal.
