Our company's product, the Tunnel Construction Step-up Transformer GSE, and the Step-up Transformer GLB (Stabilizer), are designed for long-distance tunnel construction where voltage is low and unstable. They address the issue of frequent failure of tunnel construction equipment such as pumps, scraper machines, rock drills, water pumps, and air compressors. Our products solve these challenges and are widely used in tunnel construction projects across the country, directly supplied to large-scale engineering enterprises like China Railway, China Communications Construction Corporation, and China Electric Power Construction Corporation. The Tunnel Construction Step-up Transformer GSE optimizes the power supply scheme, replaces high-voltage entry, requires no wiring changes, is easy to install, saves construction costs, meets the power demands of tunnel construction, and enhances the efficiency of engineering projects.
Tunnel boosters can resolve issues caused by low grid voltage below 300 V or even lower, excessive line length leading to voltage drop, and overabundance of equipment causing all devices to struggle to start and operate normally. The use of tunnel boosters can raise the voltage to 380 V or higher, ensuring electrical equipment operates smoothly and functions properly.

Tunnel Construction Boost Transformer Characteristics and Advantages
1. Solves issues with low voltage (300V-380V) in the low-voltage grid due to insufficient high-voltage grid capacity during peak electricity usage (below 10KV), ensuring normal operation of equipment.
2. This product can resolve issues where the voltage in the high-voltage power grid is normal, but the transformer output does not reach above 380V, due to excessively long low-voltage lines (up to 5000 meters), causing the equipment to operate irregularly.
3. Due to the excessive number of electrical appliances used in this product, the voltage is too low to power all devices to start operating.
4. This product can save approximately 40-50% in costs compared to using a generator set for power generation.
5. Voltage regulators typically have high requirements for the working environment, mainly due to the sensitive integrated circuits that require optimal conditions and are prone to damage; carbon brushes respond slowly, failing to meet the startup requirements for transient high voltage needs; the purchase cost is slightly higher than this product, with a shorter lifespan and higher maintenance costs. This product can address the issue of transient high-voltage startup, offering lower purchase and maintenance costs, and is easy to install with minimal environmental requirements. It is compact, making it convenient for mobile operations.

Transformers are a common electrical equipment used to convert a certain value of alternating voltage into another value of alternating voltage at the same frequency. Step-up transformers are specifically designed to convert lower values of alternating voltage into a higher value of alternating voltage at the same frequency. They are widely used in high-frequency applications such as inverters.
