Ultra-fine dry powder fire suppression system for electrical control cabinets

A specialized ultra-fine dry‑powder fire suppression system for electrical control cabinets can swiftly extinguish fires in distribution boxes, high‑ and low‑voltage switchgear rooms, low‑voltage communication control cabinets, cable trays, and similar spaces, effectively reducing casualties and property damage caused by aging or overloaded wiring. 1. Utilizes ultra‑fine dry‑powder fire suppression technology, offering high extinguishing efficiency, safety, and non‑toxicity; 2. Employs advanced actuation technology, enabling pressureless storage and simplified maintenance; 3. Incorporates thermal‑sensitive wire detection, with thermal‑sensitive wires strategically deployed in areas prone to ignition, ensuring highly targeted fire suppression; 4. Features both manual and automatic activation modes, allowing round‑the‑clock monitoring of fire conditions within the protected zone.

Power-Specific Ultra-Fine Dry Powder Fire Extinguishing System

The dedicated dry‑powder fire‑extinguishing system for electrical equipment features temperature‑controlled activation, electrically controlled start-up, and start‑up feedback. It can independently detect fire signals and automatically initiate extinguishing, delivering round‑the‑clock, unattended, automated fire suppression. The system employs pressureless storage and is easy to maintain; its ultra‑fine dry‑powder extinguishing agent offers high extinguishing efficiency, safety, and non‑toxicity, with electrical insulation ratings of no less than 10 kV. A network of piping and dispersal‑type nozzles ensures comprehensive coverage of all protected spaces within the transformer cabinet. This product is specifically designed for transformer cabinets, high‑ and low‑voltage control panels, and cable trenches, enabling rapid suppression of Class A, B, C, and E fires.

Unmanned aerial vehicles and specialized fire-extinguishing devices

The drone features a completely new airframe architecture and a modular design, offering exceptional versatility. With a hexacopter configuration, it enables vertical takeoff and landing and is specifically tailored for challenging fire scenarios in power‑generation and chemical‑plant facilities, supporting a payload of 100 kg. Its integrated firefighting system comprises a steel housing, fire‑extinguishing agent, a control valve assembly, high‑purity nitrogen, and a flow‑directed spray nozzle assembly. During discharge, the spray angle is continuously adjustable from 0° to 80°, facilitating efficient suppression and containment of large‑area fires. The system can deliver either continuous or intermittent, multi‑pulse sprays, effectively tackling incipient or developing fires in wind turbine nacelles as well as urban high‑rise building fires.
