1 Before equipment installation, please first refer to the following materials carefully: this manual, nameplate and overall dimensional drawings, thus to get familiar with the product’s total weight and installation methods and prepare corresponding lifting facility and special tools.
2 The transformer should be kept at least 300mm away from walls and other equipment during installation. Transformers installed side by side should have at least 300mm clearance.
3 The minimum safe distance between conductors and ground should conform to IEC76-3-1 POWER TRANSFORMERS-INSULATION LEVELS AND DIELECTRIC TEST-EXTERNAL CLEARANCES IN AIR.
4 The minimum safe distance between the HV coil and ground is listed as follows:
|Net distance (mm)||40||60||90||120||160||250|
5 Usually, the transformer can be placed directly onto the service site and then be put into operation after installation and inspection. If the transformer must be fastened in place for shock-proof purpose or if there are other special requirements, bolts should be embedded into the foundation. The position of the bolts should be in line with the installation holes of the transformer according to outline drawings. To secure the transformer, remove the wheels and bolt the transformer to the foundation.
6 The connections between live parts must be secure. The torque to be applied is listed as below:
