Teziutlán HUB
Modernisation of Teziutlán HUB in Puebla: medium- and low-voltage power, emergency backup, DC systems, cooling, grounding and coordinated civil works.
Grupo Arcondec carried out the modernisation of Teziutlán HUB in Puebla. The project combined medium- and low-voltage power renewal, emergency backup, DC power, cooling, grounding and building modifications.
The documented scope includes a 13.2 kV incoming supply and an 80 kW / 100 kVA emergency generator replacing the existing 40 kW unit. Distribution includes 600 A I-Line switchboards for normal and emergency service, automatic transfer, remote monitoring and surge protection.
The DC power plant has a capacity of 96 kW and specifies twenty 3 kW rectifiers, providing 60 kW of installed rectification. Backup comprises two 800 Ah lithium battery banks at 48 VDC. The 30 kVA inverter system specifies six 2.5 kVA modules, providing 15 kVA installed, and 25 regulated AC outputs to racks.
Cooling comprises two 20 TR packaged units, a 3 TR minisplit and relocation of three existing units. The scope also covers the steel structure, enclosures, flooring and supporting installations. Arcondec reports a four-month execution period and delivery in 2022; capacities and quantities described here come from the project’s Annex C.
The challenge
The renewal combined power, backup, cooling and civil works at an operational site. Planning included a temporary 50 kW generator for three weeks to support emergency generator replacement and a night-time connection of the new incoming supply. Coordination had to sequence load migration, grounding integration and on-site works with the objective of protecting service continuity.
The Arcondec solution
Medium voltage and coordination. 13.2 kV supply, pad-mounted transformation, 15 kV XLP cable, HDPE ducts, manholes, terminations and VLF testing. Scope includes a new CFE contract, UVIE verification and public-road permits.
Distribution and backup. 600 A normal and emergency switchboards, two 200 kA surge protectors and an 80 kW / 100 kVA generator with automatic transfer, SNMP monitoring, a 500 L tank and an acoustic enclosure.
DC and regulated power. 96 kW Eltek DC plant with 60 kW installed rectification, a six-panel 400 A BDFB, two 800 Ah lithium banks and a 30 kVA Alpha inverter with 15 kVA installed.
Cooling. Two 20 TR packaged units, a 3 TR minisplit, insulated ducts, grilles and relocation of three existing minisplits.
Cable routing and grounding. Feeders, ladder cable trays and galvanised conduit. Physical and isolated electronics grounding grids with 12 ground rods, master bars and interconnection to the existing system.
Civil works and installations. Steel structure, wall and roof insulated panels, louver facade, Durock walls, glazing, gate, painting, signage, plumbing and 45 LED luminaires.
