Life extension

Often buying new equipment is not the most beneficial option. Most switchgear is designed to last 40 years or more with proper maintenance, and replacing it can be costly. Engineering installation and lost profits from outages can often double or triple the price of new equipment.

Currently the owners of high voltage electrical equipment face growing challenges regarding demand and energy efficiency, while must take care and / or reduce operating costs.

To achieve these objectives, various tasks as specialized site assessments, periodic inspections, overhaul average life and refurbishment for life extension, use relay timing to reduce the dynamic stress during maneuvers operation, and devices currently being developed online monitoring.


Renewal and replacement parts for switches low, medium and high voltage and any power distribution.

We are able to provide new engine controls and OEM General Electric, or repower equipment we can offer to your needs.

We have the best prices around the market, being the leaders in our field.
