Frequently Asked Questions (FAQ)
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 manifestations of insulation aging of the windings in dry-type transformers?
A:The insulation layer of the windings has changed color, cracked and fallen off; the insulation resistance and polarization index have significantly decreased; there is local overheating and peculiar smell during operation; abnormal discharge sounds occur.
Q:Why does the transformer oil turn black? And how should it be dealt with?
A:Reason: The oil quality has severely deteriorated, and the internal temperature has risen, causing the oil to carbonize; faults in the windings or the core have generated arcs, leading to the decomposition and carbonization of the oil. Treatment: Replace all the qualified transformer oil; remove the core and conduct an inspection to eliminate internal overheating or discharge faults.
Q:What types of transformers do you produce?
A:Our product range includes oil-immersed transformers (S11, S13, SZ11, SZ13, SFZ11, SFZ13), dry-type transformers(SCB, SG), special transformers, prefabricated substations (ZGS, YBM, XBF), amorphous alloy transformers (SBH), transformers for new energy applications, high and low-voltage switchgear and complete sets (XGW, DFP, MNS, GGD), and various transformer accessories.
