Description
Switchgear Foundation & Layout
Switchgear foundations, anchor points, cabinet clearances and maintenance passages are coordinated against the equipment list before fabrication. This allows the enclosure and equipment interfaces to be produced together, so site work can focus on positioning, connection and commissioning instead of late structural adjustment.
Cable Entry, Sealing & Earthing
Cable entry locations, route directions, sealing method and internal earthing bars are confirmed during technical review. ETENZ can prefabricate cable openings, fire-rated seals, trays and external earth terminals to match the approved protection and installation requirements.
Finished E-House Delivery
For projects requiring a complete product, ETENZ can deliver the finished E-House with MV/LV switchgear, auxiliary distribution, HVAC, lighting, monitoring and fire-safety interfaces integrated and checked according to the agreed inspection plan.

Product Features
|
MV equipment fit |
Structure, foundations, clearances and access are engineered around MV switchgear, transformers and instrument transformers. |
| Factory-Coordinated Interfaces | Trays, earthing, cable entries and seals are completed in the factory, ready to connect and install on arrival. |
| Finished Delivery | The complete level integrates enclosure, switchgear, HVAC, power, monitoring and fire interfaces into a finished E-House. |
| C3-C5 Finish | Coating, fasteners, louvers and seals are configured to the site corrosion class — standard C3, up to C4/C5. |
| 25-year structural life | Profiles, galvanized panels, welds and sealing with the C3-C5 system are built to a 25-year structural design life. |
| Expansion Ready | Spare bay positions and cable routes can be reserved for phased power-distribution projects. |
