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 is the function of the residual current circuit breaker?

The residual current circuit breaker is mainly used to detect the leakage situation (current leakage) in the circuit and quickly cut off the power supply when leakage occurs to prevent electric shock accidents or electrical fires. It can also provide overload and short - circuit protection.

Q:What are the payment terms?

T/T payment method is supported to provide customers with convenient payment options.

Q:What is the difference between a molded case residual current circuit breaker and an ordinary circuit breaker?

On the basis of having the overcurrent protection function of an ordinary circuit breaker, the molded case residual current circuit breaker additionally adds the residual current protection function. It can detect the leakage current in the circuit and quickly cut off the circuit when the leakage current reaches the set value, thus effectively preventing the occurrence of electric shock accidents. It can be said that the molded case residual current circuit breaker provides more comprehensive po

Q:What are the installation requirements for the residual current circuit breaker?

1.It should be installed by professional electricians to ensure compliance with electrical specifications. 2.Install it in the distribution box to ensure correct wiring and correct connection of live wire, neutral wire and ground wire. 3.After installation, tests should be carried out to ensure that the residual current protection function is normal.

Q:How to test whether the residual current circuit breaker is working properly?

Press the test button on the residual current circuit breaker every month, and the circuit breaker should trip. If the circuit breaker does not trip after pressing the test button, it indicates that the residual current protection function is invalid and needs to be replaced.
