YBMD-12/24 series buried box substations, — Product Overview
The YBMD-12/24 series buried box-type substation is designed and manufactured by VoltCloud Electric. The substation body is buried fully or partially underground — a landscape-type power supply facility developed for municipal construction. It resolves the conflict between scarce urban land and street-level clutter: small footprint, environmentally clean, low noise, low losses, and a visual appearance that integrates with the surrounding environment. It can also carry advertising or display functions.
VoltCloud Electric engineers and manufactures this equipment for utility, industrial and renewable-energy projects. Every unit is routine-tested before shipment and delivered with test records and export documentation. Ratings shown below are from our current production data — non-standard capacities, voltage ratios and loss classes are engineered to order.
