Frequently Asked Questions (FAQ)
Q:Is it more appropriate to choose a transformer or a distribution box for the power distribution in the community?
A:The box-type transformer is suitable for urban residential communities. It has a high degree of integration, occupies a small area, has a clean appearance and low operating noise. It can be directly placed in the green belts or power distribution rooms of the community. The pole-mounted transformer (tower-type transformer) is suitable for suburban or rural communities. It has a low cost and is easy to install. It is erected on utility poles and is suitable for scenarios with dispersed loads.
Q:What Does Your Product Portfolio Cover?
A:Our product portfolio 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), new energy transformers, high and low-voltage switchgear (XGW, DFP, MNS, GGD), and various accessories.
Q:What are the special selection requirements for transformers that are matched ？
A:It features low loss and low noise; the short-circuit impedance needs to match the inverter; it has strong resistance to voltage fluctuations and harmonic impacts; the transformer for photovoltaic power stations needs to adapt to significant changes in load throughout the day and night; the transformer for wind power needs to be able to withstand outdoor high-altitude and low-temperature environments, with a protection level of no less than IP54.
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.
