AMC Coverage
Transformer is the most expensive & the most critical asset in the electrical system. It becomes very important to get the Transformer Routinely Serviced by the Specialists. For a Trouble-Free Operation & Uninterrupted Power Supply, We Recommend the user for the AMC services.
The AMC plans are Tailor-Made after Identifying & Accessing the User's need. Monthly, Quarterly, Bi-Annual, Annual Service Visits are planned to Identify all the Weak Areas and Rectify them before the problem becomes a Catastrophic Failure Resulting in Heavy Losses.
With over Two & A Half Decades of experience in O&M of Transformers. The user can stay assured that our recommendations are reliable and our services are unmatched.
Benefits Of AMC For Transformers :
- Increases the life of your Transformer
- Better Returns on Investment. (The AMC Cost comes out to be less than 1% of the Transformer's cost).
- Cost-effective In case there's damage, repairing cost will be very less than the cost of new Transformer Regular maintenance of Equipment will ensure no major damage occurs for a longer period.
- Healthy life of your Sub Station. Your Electrical Substation is a major and costly part of any Electrical transmission & distribution system. A healthy transformer can assure a healthy electrical system.
- Optimum performance by your Electrical equipment.
