We are a trusted Marshalling Box Manufacturer in India, offering high-quality marshalling boxes designed for power transformers, distribution transformers, substations, and industrial electrical systems. Transformer marshalling boxes are essential components used for cable termination, control wiring, alarm circuits, monitoring systems, and protection connections in transformer installations.
A marshalling box acts as a centralized interface between transformer accessories and external control or monitoring systems. It helps organize electrical wiring safely and efficiently while protecting control components from dust, moisture, heat, and outdoor environmental conditions.
 
The marshalling box houses:
Terminal blocks
Control wiring
Protection relays
Space heaters
MCBs and switches
Annunciation circuits
Monitoring and alarm connections
 
It provides a secure and organized system for connecting transformer instruments such as:
Oil Temperature Indicators (OTI)
Winding Temperature Indicators (WTI)
Buchholz Relays
Magnetic Oil Level Gauges (MOG)
Pressure Relief Devices (PRD)
Cooling fan circuits
