Installation Instructions:
1. Installation form:
The installation of 20kV oil-immersed transformers is versatile, accommodating various methods such as pole-mounted installations, outdoor setups, and indoor transformer installations. Each method is designed to optimize performance and ensure seamless integration into your power system.
For outdoor installations, it is imperative to secure the transformer on a reinforced concrete foundation, providing stability and durability. Indoor installations require the transformer body to be perfectly aligned with the front of the cabinet, ensuring it adheres closely to the distribution panel for optimal performance.
2. Installation steps:
When positioning the transformer, utilize designated special force points for maximum safety and effectiveness. Implement anti-slip measures to secure the transformer firmly in place during the installation process.
Maintain controlled inclination during transportation and installation, with a maximum tilt of 15° along the long axis and 10° along the short axis, ensuring structural integrity and operational efficiency.
During installation, ensure proper spacing between components to avoid any excessive tightness or looseness, thereby maintaining the transformer's efficacy and durability.
When installing terminals, select appropriate insulation disks based on actual conditions, ensuring correct wiring for optimal electrical performance and safety.
3. Attachment installation:
Install additional components like gas relays, pressure relief devices, moisture absorbers, and sleeves in strict accordance with relevant standards and manufacturer guidelines, ensuring each part enhances the transformer's functionality and safety.
