High-Voltage Substations
At ABTECNICO ENERGY, we provide end-to-end solutions for High-Voltage (HV) Substations — from design and engineering to procurement, installation, testing, and commissioning.
Our expertise covers Air-Insulated (AIS) and Gas-Insulated (GIS) substations up to 400 kV, serving utilities, industrial facilities, and renewable energy plants with safe, efficient, and reliable power transmission and distribution systems.
We take pride in our turnkey EPC capability, delivering substations that integrate seamlessly into existing grid infrastructures and comply with the highest international standards such as IEC, IEEE, and IEC 61850 for communication and automation.
Our Engineering & Design Expertise
Our highly skilled engineering team designs substations that optimize performance, safety, and operational flexibility.
We utilize advanced software tools for load flow analysis, short-circuit studies, and protection coordination, ensuring the electrical network operates with maximum efficiency and reliability.
Key engineering activities include:
Primary and secondary substation design (SLDs, protection schemes, control logic, and wiring diagrams)
Selection and sizing of switchgear, circuit breakers, current and voltage transformers
Layout design for equipment, busbars, and cable routing
Earthing and lightning protection system design
Integration of control and protection panels
Interface engineering for remote control and SCADA systems
