Tunnel Long-Distance Step-Up Transformer | Construction Site Booster

Oil-immersed booster for voltage-drop compensation on long tunnel feeders

HK$3000.00

Overview

Nelink tunnel step-up transformers solve the severe voltage drop caused by long cable runs in tunnel, mining and remote-site construction, boosting and stabilising supply so equipment at the working face receives its rated voltage. Available as bare oil units or integrated into weatherproof outdoor cabinets.

Key Features

  • Compensates voltage drop over long feeders, stabilises equipment supply

  • Step-up configurations such as 0.4 kV to 10 kV, or custom ratios

  • Oil-immersed rugged design for continuous heavy site duty

  • Optional IP54 outdoor cabinet with meters and switchgear

  • High overload capacity for motor starts and impact loads
