Multi V Rosarito: 750 kVA transformer
Published: 750 kVA transformer, trenches, ducts, and TAB GH panels. Photos are on the medium-voltage portfolio.
Who installs electrical substations in Tijuana? Alianza Electromecánica, trade name of Luis Enrique Laija Pacheco (persona física), office at Nicolás Bravo 2936, Col. Colosio Delmatamoros, CP 22204, Tijuana, B.C., installs medium-voltage substations for industrial buildings and clinics: pad civil work, manholes, transformer, panels, and CFE coordination under one contract. Phone (664) 604-1810. The published electrical service is medium and low voltage.
The substation is the deliverable here: transformer, panels, and the utility coordination the contract names. The medium-voltage page covers duct banks, pads, and the yard. The two pages link to each other.
Medium voltage
Who. Alianza Electromecánica, trade name of Luis Enrique Laija Pacheco (persona física), registered in May 2016, office at Nicolás Bravo 2936, Col. Colosio Delmatamoros, CP 22204, Tijuana, B.C.. Email lapl7212136q2@gmail.com. In existing buildings the scope is MEP fit-out and installations. The substation sits with the electrical installation and panels when the contract asks for both.
Published field work includes the pad, manholes, trenches, ducts, and transformer setting. 480 V distribution is on the industrial electrician page in Spanish and on electrical installations in Tijuana.
A CFE load increase in Tijuana changes the transformer or the main panel when the load study no longer fits the installed equipment. Alianza quotes that change as medium- and low-voltage work. This page does not publish a kVA range beyond the two jobs already on the site.
Clínica REYMAR is published as 300 kVA, low-voltage electrical work, and HVAC, with two operating rooms aligned with COFEPRIS. The site does not write “Tijuana” on that project name.

Scope
Published medium-voltage scope: civil pad, trenches, ducts, and manholes; transformer setting; panels and associated low voltage. What is not in that list is not a promise of this page.
Published transformer jobs: 750 kVA at Multi V Rosarito (trenches, ducts, TAB GH panels, grounding, and LEED lighting on the home-page card) and 300 kVA at Clínica REYMAR. Alianza is not a store. Equipment supply is defined by the contract.
High voltage is not a service. The guides are UVIE / NOM-001-SEDE and how a plant is energized with CFE.
Published work
Published: 750 kVA transformer, trenches, ducts, and TAB GH panels. Photos are on the medium-voltage portfolio.
Published: 300 kVA, low voltage, and HVAC, two COFEPRIS operating rooms. The site does not claim a pad-mount on every card and does not name the city on the project.
FINSA El Salto is published as canalizations in Jalisco, not as Tijuana work. Multi IV Otañez is published as office air conditioning, facade, and civil work. The site does not claim a pad-mount at Otañez.
