Dry Type Transformer and LV Switchgear for Data Center Power Room
Project Overview

Project Snapshot

A dry type transformer and low voltage switchgear package supplied for a data center power room in Singapore, supporting indoor power distribution, redundancy planning, equipment documentation, factory testing and delivery coordination.

This project involved the supply of indoor dry type transformers and low voltage switchgear for a data center power room in Singapore. The equipment was selected to support critical power distribution, indoor installation requirements and coordinated connection with the downstream UPS and facility electrical systems.

Before production, the project specification, single-line diagram and switchroom layout were reviewed to confirm transformer capacity, voltage ratio, cooling arrangement, enclosure requirement, LV busbar rating, incoming protection, outgoing feeder arrangement and cable entry direction.

The transformer and switchgear package was manufactured with the required inspection records, drawings and technical documents before shipment, helping the project team reduce approval and installation uncertainty.

How We Delivered

Challenge And Solution

The requirement on site, and how the specification, drawings, and production were supported.

The Challenge

Project Requirement

<p>The project required an indoor oil-free transformer and low voltage switchgear package suitable for a data center power room. Key items needed confirmation before production, including transformer capacity, ventilation space, enclosure protection, LV busbar rating, feeder arrangement, incoming protection, cable entry direction, monitoring contacts and document approval requirements.</p>

Our Solution

What We Supported

Our engineering team reviewed the specification, SLD and switchroom arrangement before preparing the technical proposal. The dry type transformer configuration, enclosure, cooling arrangement, temperature monitoring, LV switchgear feeder schedule and protection requirements were checked against the project documents.

Based on the confirmed requirements, we prepared a coordinated transformer and LV switchgear package with datasheets, arrangement drawings, wiring references, testing documents and shipment support to reduce approval and installation risk.
