Installation Instructions:
1. Installation Form:
The installation of 20kV oil-immersed transformers can be executed in various styles including pole-mounted, outdoor, or indoor settings.
For outdoor installations, secure the transformer on a reinforced concrete foundation. For indoor placements, ensure the transformer body aligns perfectly with the cabinet front, creating a seamless attachment to the distribution panel, without any gaps.
2. Installation Steps:
When positioning the transformer, utilize the designated force points specific to the product, and employ anti-slip precautions.
Maintain a controlled inclination of the transformer during transit and installation: no more than 15° along the long axis and 10° along the short axis.
During setup, ensure appropriate spacing between components to prevent excessive tightness or looseness.
For terminal installation, choose insulation disks that match the operational requirements and ensure proper wiring.
3. Attachment Installation:
While installing accessories such as gas relays, pressure relief devices, moisture absorbers, and bushings, adhere strictly to relevant standards and manufacturer guidelines.
