检查，检查 |
| We intricately check the condition of equipment，identity parts where rust，corrosion，and other deterioration is occurring，and check the progress of the deterioration。 |
We discuss work details based on the results of the equipment check and survey，and offer the details to the customer。 |
Our specialists carry out the work following the agreed upon plan。 |
Once completed，we check to ensure the work was completed according to the plan and verify conditions before delivery。 |
We offer leaked oil prevention that does not require equipment to be shut down or taken apart。

Seam Coat is a coating film that prevents oil leakage，developed by Midas Safety Co.，Ltd。
Examples
水保护凸缘上的Gas Insulated Switchgear（Caulking）
When rainwater and other moisture gets in through the flange joints of gas insulated switchgears，internal rusting progresses and this can lead to gas leakage.Defets have also been reported where the water retained inside can freeze， adding excess stress to insulation spacers and causing cracks to occur.We caulk flanges with the appropriate procedures to prevent these kinds of defects。
核心部件的修复
Some repairment can not be done easily，as severing the control wiring laid inside wire ducts can have a major impact on equipment operations.We can make these repairment without severing the control wires，according to the construction of the wire duct and the state of rust and corrosion。
