Frequently Asked Questions (FAQ)
Q:Which type of transformer is more suitable 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 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 the three-phase voltage imbalance in the transformer?
A:The positions of the transfer switch are inconsistent; there is a short circuit between the windings (in a certain phase); the three-phase load is severely unbalanced; the system voltage is unbalanced across the three phases.
