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 and 4P molded case circuit breakers?
A:
3P breakers control three live wires (L1, L2, L3) for three-phase three-wire circuits and balanced loads. 4P breakers add a neutral wire, suitable for three-phase four-wire systems, allowing simultaneous cutoff of phase and neutral wires to prevent abnormal neutral current.
Q:What are the precautions for wiring 3P molded case circuit breakers?
A:
1. Strictly connect three-phase live wires according to L1, L2, L3 marks to ensure correct phase sequence and prevent motor reversal. 2. Use copper wires or bars with cross-sectional areas matching the rated current to ensure good contact and avoid heating from excessive resistance.
Q:What are the reasons for inconsistent tripping of the three phases?
A:
Common reasons include: 1. Tripping mechanism failure (worn/stuck springs or locks). 2. Poor contact of contacts due to oxidation, ablation, or loose wiring. Solutions involve checking/replacing parts, cleaning contacts, or tightening wiring.
Q:What product tests are conducted before leaving the factory?
A:
We conduct comprehensive tests including electrical performance testing, mechanical performance testing, appearance inspection, and temperature rise tests to ensure product quality meets standards.
Q:How are the molded case circuit breakers packaged?
A:
We use carton, cardboard box, and wooden box packaging, all complying with international export standards, to ensure products are not damaged during transportation.
