$6500.00
Overview
Nelink tunnel step-up transformer is a dedicated voltage regulation transformer designed for long-distance power supply in tunnel construction and operation. It boosts the input voltage to compensate for line voltage drop over long cable distances. Available in two types: dry type (enclosed cabinet with control panel and meters) and oil immersed type (with radiator fins and upper control box). The enclosure is equipped with analog meters and control buttons for real-time monitoring. Suitable for tunnel construction sites, highway tunnels, railway tunnels, underground projects and mining sites. Compliant with GB and IEC standards.
