Prefabricated Enclosure Manufacturing and System Integration

The control E-House for a second DC de-icing system is in place at China Southern Power Grid's 500 kV Liping substation. At 11.4 × 5.6 m, the twin-module unit is the largest by volume of the power line de-icing enclosures ETENZ has built for NR Electric, a series that also covers truck-mounted units, fixed-station containers, and filter and valve enclosures.

On-site E-House assembly is complete for the GIS building at the Huadian Yancheng Honggang solar project: eight modules ETENZ built for Sieyuan Electric now form one 22 × 11 m equipment building housing 220 kV GIS.

Modular data center reliability depends on what each module delivers: bus maintenance, access at module interfaces, and the handover from factory tests to site commissioning. Tier, TIA-942 and ISO/IEC 22237 provide different frameworks for these decisions.

AI data center power architecture must hold up when one feed is lost and equipment is taken out for maintenance. Start at the server power inputs, then size the A/B paths, UPS backup, rack PDUs and metering around the required operating state.

Quotations become comparable once the liquid cooling interfaces are written down. Start from the server platform, then fix CDU scope, duty points, flow balance and pressure ratings, coolant chemistry, and what happens when cooling is lost.

Power, cooling and layout in AI data center infrastructure all follow from one decision: the server platform. What to settle first, from rack power and liquid-cooling heat rejection to module layout and factory prefabrication.
