With the rapid development of cities, the increasing number of buildings, extensive use of flammable materials, and insufficient public awareness of fire prevention have significantly raised the risk of fires. Although most buildings are equipped with fire suppression systems, experience has proven that the success of firefighting efforts largely depends on the integrity of fire water supply equipment. Fire pumps are critical components of these systems, yet they remain idle for long periods. This dormancy, combined with damp pump room environments, often leads to issues such as corrosion of pump shafts and impellers, seizure of mechanical parts, and failure of electrical components. Consequently, when a fire occurs, faulty fire pumps may fail to operate, jeopardizing lives and property.

HYB New Energy Prefabricated Substation (European-style compact substation, abbreviated as "European substation"; a structural form where the transformer is oil-immersed and the radiator is exposed outdoors is also called "Chinese-style substation") is an integrated high/low-voltage prefabricated substation that combines step-up transformers, high-voltage switchgear, low-voltage switchgear, and corresponding auxiliary supporting devices. Its voltage rating is 35kV and below, with a capacity range of 100~6300kVA, primarily designed for the new energy industry.

The ATS Series Dual Power Supply Control Equipment is a high-performance, safe, reliable, and highly automated power switching device with a wide range of applications. It is designed for use in AC 50/60Hz power supply systems, where it automatically switches between the main power source (N) and the backup or generator power source (R) when one of them fails (e.g., power outage, under-voltage, over-voltage, phase loss, or frequency deviation).

The New Energy AC Combiner Box is a critical component in photovoltaic string power generation systems, connecting string inverters to AC distribution cabinets or step-up transformers.、 This combiner box uses circuit breakers for input and circuit breakers or load isolation switches for output. After busbar combining, it provides secondary lightning protection. The system's maximum rated voltage is AC690V, and its protection rating is IP65—equivalent to string inverters—meeting requirements for outdoor installation, waterproofing, dust resistance, UV resistance, and salt spray corrosion resistance.

The combiner box boasts an IP65 protection rating, providing waterproof, dustproof, rustproof, and salt spray resistance, making it ideal for outdoor installation. Utilizes PV-specific high-voltage surge protectors to safeguard the combined positive/negative busbars against ground faults. Continuous operating voltage (Uc) reaches DC1500V. The monitoring module employs reliable Honeywell Hall elements (DC CT sensors) to collect data on each string’s current, busbar voltage, and temperature. It provides alarm functions, local fault diagnosis, and monitors surge protector and circuit breaker status.

All metal enclosures are made of cold-rolled steel plate or stainless steel plate, with a protection rating of IP54 or higher, suitable for outdoor installation. The enclosure adopts a three-layer design: the top layer serves as a brim to prevent rainwater from entering; the middle layer houses the photovoltaic metering meter, allowing data observation through a transparent glass panel, and includes a seal interface on the door lock; the bottom layer is designed for control and protection, facilitating maintenance and inspection.

The BWG PV Grid-Tie Cabinet serves as the core interconnection equipment for photovoltaic power station systems, specifically designed to enable efficient grid integration of solar power generation. It features comprehensive circuit protection capabilities, precisely monitoring anomalies such as overvoltage, overcurrent, and short circuits to ensure safe and stable system operation. Integrated with an intelligent metering module, it collects real-time key data including power generation output, grid-connected current and voltage, facilitating remote monitoring and operational management for users.

This system adopts an integrated electrical design, where all equipment except the battery system is pre-assembled and optimized, providing a complete "plug-and-play" solution to users. Through pre-configuration and optimized design, customization requirements are minimized, reducing potential safety hazards caused by on-site installation variations and management risks.

The ZGS New Energy (Wind/Photovoltaic) Power Combined Transformer is an integrated unit for wind or photovoltaic power generation, combining a step-up transformer (American-style compact substation), high-voltage current-limiting fuses, oil-immersed load switches, low-voltage switchgear, and corresponding auxiliary devices. Its capacity range is 500-5800kVA, with a voltage rating of 35kV and below. It is suitable for photovoltaic and wind power farms on land, water surfaces, and offshore locations.
