AI-Powered supplier vetting

SummarySDKC Shandong Kaichuan Electric Equipment Co., Ltd. is described as a high-tech enterprise integrating R&D, manufacturing, trade, and service, with products including electrical control cabinets, motors, frequency converters, electrical components, and high- and low-voltage switchgear. It reports broad customization and ODM capabilities, new products within the past year, and OEM service for well-known brands. Its finished-product inspection instructions are reportedly uniformly followed, while service procedures exist for supplier assessment, corrective actions, and complaints; however, written records are absent for the latter two mechanisms. The supplier reports no overseas warehouse, showroom, agent or branch, or offline trade-show participation, and lists zero overseas service countries. Financial credibility cannot be confirmed because the provided financial fields report zero operating revenue, costs, profits, margins, and ratios for the stated periods, without enough context to validate the...

Supplier typeThe supplier is described as a high-tech enterprise integrating R&D, manufacturing, trade, and service. Its stated business scope centers on producing, processing, and selling electrical control cabinets, motors, frequency converters, switchgear bodies, transformers, and related electrical equipment.

After-Sales capabilityThe supplier has written procedures and records for assessing effective service capability, and reports lead times within 15 workdays in both peak and off-season periods. However, corrective and preventive action and customer-complaint procedures have no written records, while overseas service coverage is limited: zero countries and no overseas warehouse, showroom, agent, or branch.

Financial creditThe supplier reports registered capital and describes itself as a large-scale enterprise, but the financial-capacity slices report zero operating revenue, costs, profits, margins, and current ratios for the stated periods. These figures provide no positive evidence of financial strength and raise a material credibility concern, although the supplied data does not explain whether the zeros reflect actual results or incomplete reporting.

R&D capabilityThe supplier reports R&D capability, at least one new product during the past year, and ODM services. Its company description also identifies R&D as part of its integrated operation, but no usable SDK is available.

Production capacityThe supplier states that it operates manufacturing facilities and equipment including copper-bar processing machinery and an assembly line. Its described production scope covers electrical control cabinets, motors, frequency converters, switchgear, transformers, and related equipment, while finished-product inspection instructions are reportedly available and uniformly followed.

Customization capabilityBoth relevant slices explicitly list customization from samples, designs, full customization, minor customization, and flexible customization. The supplier also reports ODM availability, supporting broad product-development and customization coverage.

Product Q&A

Q:What are the common faults and handling methods of the Frequency Converter For Fans And Pumps?

1. Overcurrent tripping of the frequency converter: The cause may be sudden changes in the load of the frequency converter or motor stalling. The solution is that you can check for mechanical jamming and extend the acceleration time. 2. Motor abnormal noise: This may be caused by harmonic interference or bearing wear. It is recommended that you install an output reactor and replace the motor bearing. 3. Overheating of the frequency converter: It is caused by poor heat dissipation of the frequenc

Q:How to choose the appropriate power of the frequency converter?

Choose according to the rated power of the motor, and it is recommended to reserve 10%-20% redundancy. If the load includes impact equipment, it should be selected according to 1.5 times the rated current of the motor. For example, a 110kW water pump should choose a 132kW frequency converter.

Q:How to maximize the energy-saving effect of the frequency converter?

Enable the 'automatic energy-saving operation' function, and the frequency converter will automatically adjust the V/F curve to the optimal efficiency point. Adopt the combination of variable frequency pump and power frequency pump, and dynamically distribute the load through PID adjustment to avoid long-term high-load operation of a single pump.

Q:What is the warranty period for this product?
