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 difference between 3P molded case circuit breakers and 4P ones?

3P molded case circuit breakers are mainly used in three-phase three-wire circuits and can control three live wires (L1, L2, L3) at the same time, suitable for balanced loads such as three-phase motors and three-phase heating equipment. 4P, on the basis of 3P, adds a neutral wire, which is suitable for three-phase four-wire circuits and can cut off the three-phase power supply and neutral wire at the same time. It is often used in power distribution systems with neutral wires or scenarios where

Q:What are the precautions for wiring 3P molded case circuit breakers?

When wiring 3P molded case circuit breakers, attention should be paid to: 1. Phase sequence connection: Strictly connect the three-phase live wires according to the marks (L1, L2, L3) to ensure the correct phase sequence, otherwise it may cause the three-phase motor to reverse. 2. Wiring method: Copper wires or copper bars can be used for connection. The cross-sectional area of the wires must match the rated current to ensure good contact and avoid heating caused by excessive contact resistance.

Q:What are the reasons for inconsistent tripping of the three phases of the 3P molded case circuit breaker?

Common reasons are: 1. Tripping mechanism failure: Parts such as the tripping spring and lock of one pole are worn or stuck, resulting in delayed or no action. It is necessary to check and replace the damaged parts. 2. Poor contact of contacts: Oxidation, ablation or loose wiring of contacts in a certain phase causes abnormal current in that phase, leading to inconsistent protection actions. It is necessary to clean the contacts, tighten the wiring or replace the contacts.

Q:What product tests do you conduct on molded case circuit breakers before leaving the factory?

Electrical performance testing, mechanical performance testing, appearance inspection, temperature rise test, etc.

Q:How do you package the molded case circuit breakers?

We use carton packaging, cardboard box packaging, and wooden box packaging (all comply with international export standards).
