Switchgear Solutions for Data Centers & Telecom Facilities
Data center and telecom facility power systems share one non-negotiable requirement: the load cannot go down. Whether it's a hyperscale campus, a multi-tenant colocation facility, or a telecom central office, the switchgear behind the racks has to support redundant supply paths, allow maintenance without interrupting live circuits, and scale as capacity grows. Zhejiang Gangheng Electric has manufactured HV and LV switchgear since 2004, supplying power distribution equipment for industrial and commercial facilities across Asia, the Middle East, and Africa. Below, find product recommendations organized by facility type, based on real electrical and operational requirements.

Switchgear for Hyperscale & Cloud Computing Data Centers
Hyperscale facilities are built around N+1 (or 2N) redundancy from the utility connection all the way down to the rack - a single fault anywhere in the chain must never interrupt server load. This means multiple incoming HV feeds, high-current LV busbar systems sized well above continuous load, and a maintenance philosophy where any single unit can be isolated and serviced without shutting down the busbar it sits on. Procurement is typically run by an EPC or the data center operator's own engineering team, with fast decision cycles once technical compliance is confirmed.

Recommended for HV incoming supply
KYN28A-12 Armored Withdrawable Switchgear (12kV). Handles dual or multiple utility feed configurations with a five-prevention mechanical interlock system. The withdrawable design allows a breaker to be pulled for maintenance without de-energizing the busbar section - the standard configuration wherever "no single point of failure" is a hard requirement.
Recommended for LV distribution / MCC
MNS & GCS Series Low-Voltage Withdrawable Switchgear. This is the primary recommendation for hyperscale facilities: individual feeder drawers can be isolated and hot-swapped without cutting power to adjacent circuits, which is exactly the "maintain without disrupting live load" behavior that hyperscale operators specify. Modular drawer construction also makes phased capacity build-out straightforward as server halls come online in stages.
Compliance note：All switchgear is manufactured to IEC 62271 (HV) and IEC 61439 (LV) as standard, with re-engineering to ANSI/IEEE C37 or BS EN available where an international EPC's tender specification calls for it.
Switchgear for Colocation & Enterprise Data Centers
Colocation facilities run a different set of constraints than hyperscale campuses: floor space is at a premium, tenants are billed and metered separately, and capacity has to expand incrementally as new tenants sign rather than all at once. The distribution system needs to support per-tenant or per-hall isolation without requiring a full outage every time a new circuit is added.
Recommended for HV incoming supply
GGD Fixed Low-Voltage Switchgear. A mature, cost-effective fixed-type structure suited to telecom equipment rooms and auxiliary power needs where budget efficiency and proven reliability matter more than modular flexibility.
Recommended for LV distribution
YB Series Prefabricated (European-Type) Compact Substation (50–1600kVA, 6–10kV). Factory-assembled and tested before shipment, integrating HV switchgear, transformer, and LV distribution in a single enclosure - this significantly reduces on-site installation time compared to conventional switchroom construction, which matters for telecom rollout schedules where the site needs to be live before network equipment can go in.
Compliance note：Distribution logic, metering arrangement, and interlock schemes can be customized to match the specific tenant-billing and fire-protection requirements of a given facility.
Configured for Data Center & Telecom Operating Requirements
Uninterrupted Maintenance Access
Drawer-type / withdrawable construction on MNS, GCS, and GCK series allows individual feeder circuits to be isolated and serviced without de-energizing the rest of the busbar - the core requirement for any facility where downtime has a direct revenue or SLA cost.
01
Modular, Phased Capacity Expansion
Drawer-based LV switchgear supports incremental addition of feeder units as server halls, tenant space, or telecom equipment racks are brought online - no need to over-specify capacity on day one.
02
IEC 62271 / ANSI / BS EN Standards Compliance
Manufactured and tested to IEC 62271 (HV) and IEC 61439 (LV) as standard; full re-engineering to ANSI/IEEE C37 or BS EN available for projects specified by international EPC contractors or telecom operators.
03
Rapid Deployment for New-Build & Remote Sites
YB series prefabricated substations arrive factory-tested and ready to energize, cutting installation time versus conventional switchroom construction - relevant for telecom rollout schedules and new data center campuses alike.
04
Climate-Adapted Configuration
Anti-condensation heaters, thermostat-controlled ventilation, and enclosure protection upgrades (IP54/IP65) available as standard options for high-temperature or high-humidity deployment regions.
05
Application Scenarios in Data Center & Telecom Power Distribution
Primary Utility Intake with Redundant Feeds
KYN28A-12 or XGN66-12 serves as the incoming HV switchgear, sized and configured to match single, dual, or N+1 utility feed arrangements as specified by the facility's redundancy tier.
Server Hall / Equipment Room MCC
MNS, GCS, or GCK withdrawable low-voltage switchgear distributes power to server racks, cooling systems, and support equipment, with hot-swap maintenance capability that avoids full-load interruption during servicing.
Tenant / Hall Metering and Isolation
For colocation facilities, drawer-type LV switchgear is configured with separate metering and isolation per tenant or hall, supporting incremental commissioning as new leases are signed.
Remote Telecom Site Power
Base stations, exchange buildings, or rollout sites without existing electrical infrastructure are served by YB series prefabricated substations, reducing on-site construction time.
As server halls or telecom equipment rooms expand, GH engineers replacement or additional switchgear to integrate with existing distribution layouts, minimizing disruption to live operations.
