This manual serves as a guide for the assembly and energizing of ABB 1ZCL000001EG power transformers. It outlines the necessary procedures for installation, including transportation, handling, and storage recommendations to ensure the equipment arrives in good condition. The document emphasizes the need for qualified personnel and appropriate tools to perform these tasks safely and effectively.
The guide details the specific order of assembly, starting with preliminary checks upon arrival, followed by storage requirements if immediate installation is not possible. It covers critical steps such as preliminary and final oil filling under vacuum, the assembly of radiators and expansion tanks, and various field tests including insulation resistance, polarity, and dielectric breakdown tests. Safety procedures and necessary tools are also addressed.
Each cable must offer a minimal resistance to traction of 15 tons.
There should not be any slopes greater than 25° longitudinal during transportation.
The tank is filled with dried nitrogen gas at approximately 0.2 kg/cm² to 20°C to check for leaks.
