Tunnel 800kva booster transformer long-distance construction voltage booster
Tunnel 800kva booster transformer, tunnel booster power supply is mainly suitable for electromechanical equipment in tunnels/mines. It can solve the problem that the power grid voltage is lower than 380V or even lower, the construction line is too long, resulting in low terminal voltage, and too many equipment causing all equipment to fail to start and use normally. The use of voltage booster can increase the voltage to 380-450v

Performance characteristics
1. It can handle the low voltage grid voltage (300V-380V) caused by the low voltage grid voltage (lack of 10KV) during the peak period of electricity consumption. Equipment cannot operate normally.
2. This product can handle the normal voltage of the high-voltage grid, the transformer output does not reach more than 380V, but the low-voltage line is too long (within 5000 meters), so that the equipment cannot operate normally.
3. This product uses too many electrical devices, resulting in too low voltage, which cannot meet the startup and operation of all equipment.
4. This product can save about 40-50% of the cost compared with the generator set.
5. The voltage stabilizer generally has high requirements for the working environment, mainly because the integrated circuit of the equipment requires a better working environment and is easy to damage; the carbon brush responds slowly, and the instantaneous high voltage cannot meet the startup requirements; the purchase cost is slightly higher than this product, the mission life is short, and the maintenance cost is high. This product can handle instant high-voltage startup, the purchase cost and maintenance cost are low, and the installation is simple and the application environment requirements are not high. It is small in size and convenient for mobile operation. Tunnel 800kva step-up transformer long-distance construction voltage booster

Purchase instructions
1. The user’s voltage situation requires the user to detect the no-load voltage value and the load voltage value.
2. The distance between the transformer and the electrical equipment The user needs to measure the distance between the user’s transformer and the electrical equipment in practice.
3. The user’s cable situation The user needs to check the situation of the cable he uses. Generally, it should match the total power of the equipment.
4. The total power of the starting equipment The user needs to check the total power of the equipment he uses.
Based on the above information, the user can choose the corresponding model product or make a customization.
