11kV HV switchgear installation and commissioning
11kV
Full 11kV HV switchgear package designed, supplied, installed and commissioned to IEC 62271 and Western Power Distribution requirements.
5MW
Energised on time for the developer's practical completion milestone — enabling the 5MW colocation facility to accept its first tenants.
48hr
Full commissioning documentation — relay settings, test results and O&M manuals — submitted within 48 hours of energisation.
The Project
A colocation data centre developer required a complete 11kV high-voltage switchgear package — from design coordination through to energisation — for a 5MW facility operating to IEC 62271 and a contractual uptime SLA that allowed no commissioning overruns.
IEC 62271 Design Coordination
High-voltage switchgear design for a colocation data centre is a multi-party discipline. Con-Tec coordinated directly with the structural engineer, HV panel manufacturer and the DNO protection engineer to produce a design that passed the distribution network operator's protection review first time.

Energisation Under SLA
Energisation of an HV switchgear installation in a live colocation environment — where tenants are already occupying part of the building — requires meticulous coordination of isolation, testing and re-energisation sequences. Our HV authorised persons managed the full LV isolation regime to allow HV works to proceed without impacting any live tenant circuits.



“11kV switchgear energised on the agreed date, with commissioning documentation signed off within 48 hours. Exactly what a fast-track data centre programme requires.”

Full commissioning documentation — including protection relay settings, testing results and O&M manuals — was submitted to the developer and DNO within 48 hours of energisation. The 5MW facility achieved its practical completion milestone on programme.
