Substations and Concentrators
Certified Medium-Voltage Assemblies for Switching, Protection & Distribution
Delta designs and manufactures substations and concentrators engineered for industrial, commercial, and utility-grade medium-voltage applications. Built under ISO 9001, NMX, ANSI, IEEE, and NEMA standards, our solutions deliver safe, reliable, and continuous electrical performance for mission-critical environments.
Engineered for Certified Performance, Safety & Long-Term Reliability
Delta’s substations and concentrators integrate certified switching, protection, and metering equipment inside high-durability enclosures. Built with in-house engineering and precision manufacturing, each assembly ensures long-term reliability, electrical safety, and stable operation in demanding environments.
Substation Types
Our portfolio covers a range of configurations engineered for medium-voltage distribution needs. Each type is manufactured under certified processes to ensure reliability, safety, and optimal performance.
Explore our medium-voltage configurations engineered for 7.5 kV to 38 kV applications.
RESIDENTIAL METER STACKNEMA 3R
Residential meter stacks are designed to meet the requirements of multiple metering applications. From a main cabinet for the service entrance, branch sections are connected to supply final circuits via branch circuit breakers. By using horizontal main busbars, the number of branch bases is limited only by the physical space and the current capacity of your main cabinet.

SUBESTACIÓN
NEMA 3R
A compact substation consists of modular cubicles. These cubicles are grouped together to form arrays, and each array is customized to the customer's requirements, or you can choose from common arrays that we implement. The compact substations serve the following applications: Connection and disconnection maneuvers for medium voltage distribution networks with load.Connection and disconnection of distribution transformers. As feeder panels for medium voltage in industrial and commercial applications.
