Product Overview
The 100KVA/80KW Tunnel Voltage Booster for Lighting & Ventilation is an approximately 80-100 KVA (rated 100KVA) designed for this application. Key ratings: Power Rating (KVA): 100KVA / 80KW; Rated Voltage: 3 x 380VAC (3L+N+G). Buyers searching a 100kva/80kva unit in this class get the same build with /80kw tunnel voltage booster engineering.
Brief description
When the lighting, ventilation and other equipment in the tunnel use electricity collectively, it can instantly “push” the voltage up to prevent the lights from dimming or equipment from shutting down. It is particularly suitable for tunnels over 3 kilometers long, automatically adjusting voltage fluctuations to ensure that the rescue system and monitoring equipment have sufficient power 24 hours a day.
Features
1. Heavy rain protection design ‌
100kw tunnel high power power booster Fully sealed metal shell + moisture-proof coating, can withstand water seepage from tunnel walls. Specially anti-corrosion treatment is added, it will not rust or leak electricity even if used in a damp tunnel for 5 years, and the safety level reaches IP65.
2. Remote Monitoring‌
Scanning the QR code on your phone will allow you to view real-time power data, voltage curves, and load conditions at a glance. Electricians do not need to drill tunnels, they can adjust parameters in the duty room, and an alarm text message will be automatically sent in the event of a sudden power outage.
3. Energy-saving and power-saving expert ‌
The standby power consumption is less than 1/3 of that of ordinary devices, and it can automatically optimize power distribution when running at full load. For example, when there is less traffic in the tunnel, it will intelligently reduce the output power, which can save enough electricity for 200 households for one month in a year.

Applications
1. Expert in power supply protection for ultra-long tunnels ‌
100kw tunnel high power power booster Specialized in solving the problem of “power shortage” in tunnels longer than 5 kilometers. When the ventilation system, emergency lighting, and surveillance cameras are running at the same time, it can stabilize the voltage like an “electric booster pump” to prevent the lights from dimming or equipment crashes in the second half of the tunnel.
Frequent starts and stops of trains in subway tunnels can cause voltage fluctuations. It is particularly suitable for serving as a “relay” for the subway’s emergency lighting, drainage pumps and signal systems to avoid safety accidents caused by power outages.
2. Moisture-proof guard for underwater tunnels ‌
The humidity in cross-river and cross-sea tunnels is extremely high, and ordinary equipment is prone to short circuits. It adopts a fully sealed waterproof design, and the shell can withstand the pressure of tunnel water seepage, providing stable power support for the water pumps and dehumidifiers in the tunnel.
Product details

Sturdy and waterproof‌
Thickened steel plate shell + double-layer waterproof interface, moisture-proof and water-proof, suitable for the humid environment of the tunnel.

Efficient heat dissipation‌
8 fans + honeycomb heat dissipation design, automatic strong cooling at high temperature, continuous work without heating

Simple operation‌
3-button control + mobile phone scan code to adjust parameters, the screen directly displays the power status
FAQ
Q: Does it consume power? Will it be expensive? ‌
A: It has an intelligent power saving mode, which automatically enters a low power consumption state when idle, saving 40% of power compared to the old voltage regulator. According to the industrial electricity price, the electricity bill for running 24 hours a day for a month is about 300 yuan
Q: How to repair it if it breaks? Do I have to dismantle the whole machine?
A: No!
