Frequently Asked Questions (FAQ)
Q:What are the criteria for determining when to replace an old transformer?
A:The load rate has consistently exceeded 80% and there have been frequent overloads; the losses under no-load and at full load are more than 20% above the standard; insulation has aged (with excessive dielectric loss values and deteriorated oil quality); serious faults have occurred (such as winding deformation and multiple-point grounding of the core); the energy efficiency grade is lower than level 3 and energy-saving renovations are not economically viable; it has reached the design service life (generally 20–30 years).
Q:What services do you provide?
A:We provide comprehensive end-to-end solutions and services, covering the entire process from electrical and mechanical design, quality control, material selection, core processing, winding, assembly, insulation, and testing to packaging.
Q:What are the reasons for excessive noise when the transformer is operating? How can the noise be reduced?
A:Reasons: Loosening of core, deformation of windings, resonance of components, failure of cooling system, influence of grid harmonics. Measures: Tighten the core clamps; Correct the position of windings; Adjust the shock absorption devices of cooling fans / oil pumps; Install soundproof covers; Address grid harmonics.
Q:What issues should be noted when connecting the transformer to the distribution cabinet?
A:Use copper busbars or cables for connection, with the conductor cross-section meeting the current-carrying requirements; the connection points need to be treated with tin plating or silver plating to reduce contact resistance; install lightning arresters and disconnect switches on the high-voltage side to facilitate maintenance; add insulating covers for the busbars on the low-voltage side and mark the phase sequence; after connection, check the insulation and phase sequence to ensure there are no errors.
