I. Product Overview

Electric power oil-immersed transformers have a variety of fire-fighting media and system types. Typically, water spray fire extinguishing systems are used, as well as medium and low-pressure systems.

Fine water mist fire suppression systems, synthetic foam fire suppression systems, etc., but they all activate only after a transformer fire has occurred.

Shi, it is not possible to achieve the principle of "prevention first," but the oil injection/nitrogen charging device is a fire protection facility that combines "prevention first" with "prevention and extinction together."

Shi, characterized by its economic, effective, and applicable features, has now become an important means of replacing other fire extinguishing facilities. The product itself...

Since its introduction from France in 1989, our company has a 16-year operating history in China. Our company has summarized the original products and domestic

Based on similar products, we have independently researched and developed the new-generation BHG-233 fire extinguishing device. The new device eliminates the traditional production...

Pneumatic and hammer-actuated operating mechanisms have been replaced with a brand new, all-in-one mechanical and electrical control mechanism, featuring precise actions.

Accurate and reliable. Effectively avoids the jamming of heavy weights due to corrosion of the rod track in the electromagnetic mechanism of traditional products.

Products exhibit defects such as failure to operate or unintended movement. Additionally, it effectively prevents the original product from being unusable after operation, necessitating replacement.

The defects in certain components of the device significantly reduce maintenance and upkeep costs, as well as greatly extend the product's lifespan.

Long.

The product boasts the following outstanding features:

1. Prevention-oriented, combining fire prevention with fire suppression. This can effectively prevent fires caused by the explosion of oil-immersed transformers, avoiding major losses.

Loss, conducive to the safe operation of transformers.

2. No need for water or foam-based extinguishing media, eliminating the need for fire drainage design and related facilities.

3. Eco-friendly product; this facility does not cause any pollution to the environment or the transformer itself.

4. Low cost, simple operation and management, easy maintenance.

5. This device requires two signals to be generated, and the fire suppression should occur immediately after the logic, eliminating the possibility of false operation, with a short fire suppression time.

6. Limit the damage scope caused by internal faults leading to fires, reduce losses due to transformer fires.

7. Compact structure, easy to install.

8. Unrestricted by water sources or geographical environments, it will not freeze or clog; effectively solves the issues in North China, Northwest, Northeast, etc.

The "Water-Determined Location" passive situation in the Three North regions due to water scarcity. Product Introduction
