AI-Powered supplier vetting

SummaryChongqing Blue Jay Technology Co., Ltd. is identified as a Chinese limited company and manufacturer/factory, although another record describes the business as a trading company. It reports ISO 9001 certification and references CE, RoHS, and after-sales quality control. The supplier states that it provides OEM and ODM services, has launched new products within the past year, and supports extensive customization. Production-related evidence includes two factories and more than 20,000 m² of area, while in-stock fulfillment, overseas warehouses, overseas showrooms, and overseas agents or branches are explicitly unavailable. The supplier has an export license and serves Vietnam and Malaysia, with participation in the Canton Fair. Financial information is insufficient to assess credibility, and raw-material traceability is unknown. OEM service for well-known brands is reported, but no specific customer names or cases are provided.

CertificationsThe company description explicitly states that Blue Jay is ISO 9001-certified and references CE and RoHS in its quality-control approach. The provided information does not clarify the scope, issuing bodies, or validity dates of these certifications.

After-Sales capabilityThe company description explicitly mentions after-sales in its quality-control coverage. However, no detailed service process, response standard, warranty terms, or support organization is provided, so the overall capability cannot be fully assessed.

R&D capabilityThe supplier reports new products during the past year, ODM service, design optimization support, and multiple customization modes. It has no available SDK, so software-development support is explicitly absent, but the product and design evidence supports innovation capability in hardware or product development.

Production capacityThe supplier describes two factories with more than 20,000 m² of area and is identified as a manufacturer/factory. It also explicitly lacks in-stock capacity, overseas warehouses, and overseas showrooms, while contract status for manufacturing capacity is unknown.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and states that it can help optimize designs. These records provide direct evidence of broad customization capability.

Product Q&A

Q:What detection technologies does the PDS3 use?

The PDS3 integrates ultrasonic, TEV (Transient Earth Voltage), and UHF (Ultra High Frequency) technologies to detect partial discharges.

Q:How does the system handle environmental interference?

The UHF method effectively avoids corona interference below 300MHz. For high TEV interference, ultrasonic measurement is recommended as it is less affected by radio frequency sources.

Q:What are the power supply options for the remote sensor?

The remote sensor supports 12Vdc external power or a built-in 2000mAh battery. Static power consumption is less than 10mW.

Q:What is the wireless transmission range of the sensor?

The signal transmission distance is up to 80 meters (260 feet) using 433MHz or 2.4GHz optional wireless bands.

Q:Which equipment can be monitored with this system?

It is suitable for monitoring transformers, high-voltage switchgear, and cable joints, particularly at HV cable terminations.
