Brief description of the tunnel construction booster product:

The tunnel transformer can solve the problem that the power transmission is too far, the voltage drop is too large, the voltage is lower than 300V, or even lower, the line is too long to cause the voltage to be too low, too much equipment causes all equipment to start and use normally, using a voltage booster can make The voltage is increased to 380-450v, and electrical equipment is used to start and work normally. It is especially suitable for places where the voltage is too low, such as factories, mines, roads, tunnels, bridges, irrigation, and central air-conditioning.

Characteristics and advantages of booster for tunnel construction

1 It can solve the problem that the low-voltage grid voltage (300V-380V) equipment cannot operate normally due to the low-voltage grid (less than 10KV) during the peak period of power consumption.

2 This product can solve the problem that the voltage of the high-voltage grid is normal, and the output of the transformer cannot reach above 380V, but the voltage drop is too large because the low-voltage line is too long (within 5000 meters), which makes the equipment unable to operate normally.

3 This product uses too many electrical equipment, which leads to an increase in the voltage drop of the power supply and the voltage is too low, which cannot meet the start-up operation of all equipment.

4 This product can save about 40-50% of the cost compared with generating electricity with a generator set.

5 Voltage regulators generally have higher requirements for the working environment, mainly because the integrated circuit of the device requires a better working environment and is easy to be damaged; the carbon brush responds slowly and cannot meet the startup requirements for the instantaneous startup high voltage; the purchase cost is slightly Higher than this product, the mission life is shorter and the maintenance cost is higher. This product can solve the instant high-pressure start, the purchase cost and the maintenance cost are lower, and the installation is simple and the use environment is not demanding, the volume is small, and it is convenient for mobile operations.

Selection of booster for tunnel construction

1 The user's voltage status 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 actually measure the distance between the user’s transformer and other electrical equipment.

3 User's cable condition The user needs to check the condition of the cable used by himself, generally to match the total power of the equipment.

4 Start the total power of the equipment. Users should check the total power of the equipment they use.

According to the above information, the user can choose the corresponding model product or propose customization.

Applicable site for tunnel construction booster

1 Ambient temperature: -20~85

2 Relative humidity: ≤90%;

3 The installation site should be free of gas, steam, chemical deposits, dust, dirt and other explosive and corrosive media that seriously affect the insulation of the equipment;

4 There should be no severe vibration or bumps in the installation site;

5 Prevent lightning strikes, rain, fear of fire in rainy weather, do not press equipment, do not step on it.
