Frequently Asked Questions (FAQ)
Q:What is your delivery time?
A:It is usually one month. The exact delivery time will be affected by the product and the location of use.
Q:How to clean the dust on the surface of the windings of a dry-type transformer?
A:After power outage, use dry compressed air (pressure ≤ 0.3 MPa) for blowing; stubborn dust can be gently brushed off with a brush; water or chemical cleaners must not be used; after cleaning, measure the insulation resistance again.
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 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.
