Annual Maintenance Contract Services

In many industries the productivity loss and down-time occurs due to improper routine maintenance of the electrical system. This can be prevented by the routine preventive maintenance to evaluate the failure rate of the electrical system and their components periodically. Our AMC features increases the system reliability, assures the plant load factor, enhancing productivity and decreases the down time.

Our Features

  • As per latest IEC/ISS Standards,
  • Inspection of existing systems
  • Testing & Calibration of existing electrical equipments and components
  • Update of all drawings / settings that reflect the changes
  • Record submission with scope of activities, document of all repair and/or replaced components retrofitting of existing Schemes, reengineering work, drawing discussions and approval etc.
