AI Data Center Power E-House

The mounting base for the panel lineup is built into the cabin itself: the floor channel-steel foundation is cut to the cubicle footprint, and the fixing points, cubicle-to-cubicle connection positions and earthing trunk route are fixed cubicle by cubicle at drawing stage, leaving only positioning and tightening for site. The gap between cubicle backs and the cabin wall follows the door swing angle and rear-maintenance depth, and the cable openings line up vertically with the terminals inside. The main equipment is customer-supplied or integrated within an agreed scope from third-party assemblies; its voltage, current and short-circuit ratings follow the equipment supplier's technical agreement.

Heavy outgoing circuits run at roof level. Busway is suspended along the long axis from cast-in points in the roof structure, with the suspended load accounted for when the cabin is built. Below the busway sit the power tray, the control tray and the conduit runs in turn, spaced for cable bending radius and pulling access; luminaires and detectors are kept clear of the busway centreline so a joint can be serviced without removing a light first. Tray sizes, tier count and hanger spacing are confirmed against the cable schedule.

Cables enter from underneath. The floor entry is a stainless-framed, liftable plate with a brush seal that closes back around the cables once they are pulled, keeping dust and vermin out without capping later cable additions. The opening sits directly under the cubicle termination zone, so nothing has to cross the aisle. The floor is a seamless covering with a coved skirting edge — no joints or dips to catch dirt, and heavy cubicles can be rolled in. Firestopping and waterproofing details follow the project specification.

Lighting, service sockets, HVAC supply and monitoring circuits are fed from a distribution and control assembly inside the cabin — the part ETENZ designs and manufactures: miniature circuit breakers and terminal rails are arranged in tiers, circuit numbers match the drawings, and signal terminals are reserved for a remote monitoring tie-in. An emergency stop sits at the end of the lineup and intake louvres run along the cubicle plinths, so component cooling air enters low and leaves high. Circuit schedules and the emergency-stop interlock scope are confirmed against the equipment list, with a power-up and interlock check before dispatch.

Detection, alarm, release signalling and monitoring interfaces are a fixed part of ETENZ's scope: smoke detectors are placed by in-cabin zone and the sounder-beacon goes above the doorway where it is unmissable. Wiring runs in galvanised rigid conduit with cast-aluminium junction boxes and a flexible tail into each device, and the sealing at boxes and wall penetrations is finished as one system with the cabin's ingress protection. The suppression package can be supplied and installed by ETENZ or nominated by the customer; fire ratings and acceptance follow local code and the fire contractor's scope.
