Selectric Smart Flex Low-voltage complete devices

Low-voltage complete device of increased reliability for electric power distribution and technological process management

01
Monitoring of temperature, humidity, and contact resistance of electrical connections
24/7 data on the status of contacts without inspections or thermal imaging.
02
Fiber‑optic distributed temperature monitoring
Monitoring the temperature of outgoing cables/busbars along their entire length
03
Microprocessor-based protection, monitoring and management system
Accident protection, operation history archive (event waveform) and remote control capability
04
The possibility of transitioning from scheduled maintenance to maintenance based on the actual condition.
Reducing maintenance costs and eliminating the human factor
Each function as a separate solution

All functions are independent. You can choose one, several, or none.

Each of them solves a specific task of diagnostics, protection or monitoring.

A Comprehensive Approach: From Concept to Launch

As experience shows, when purchasing equipment abroad, Russian customers face issues in monitoring fabrication processes, lead times, and logistics.

In order to solve these issues, we have created Selectric — a Russian-Chinese joint venture manufacturing.
