AI-Powered supplier vetting

SummaryNanjing Rays Optoelectronic Technology Co., Ltd. is identified as a China-based trading company established in 2025, focused on online marketing of special cables and related electrical products. Its export sales share is stated as 51%–70%, and Nanjing is listed as the nearest port. The materials also describe Jiangsu Yuhang Special Cable Co., Ltd., the manufacturing company on which the trading business is based, as having more than 300 employees, over 10 production lines, two production bases, and an annual supply capacity of 10 million meters. The evidence indicates access to substantial manufacturing resources and product customization through non-standard special cables, but it does not clearly establish that all manufacturing capabilities belong directly to Nanjing Rays. No explicit certification, after-sales process, customer case, or quality-control staffing evidence is provided. Financial figures are omitted.

Supplier typeNanjing Rays Optoelectronic Technology Co., Ltd. is explicitly classified as a trading company. Its business description states that it specializes in online marketing of special cables and was established on the basis of Jiangsu Yuhang Special Cable Co., Ltd., indicating a trading and sourcing role rather than clearly documented direct manufacturing by the target entity.

R&D capabilityThe manufacturing company associated with the supplier is described as specializing in research and development and as developing various non-standard special cables for users. Its products are also described as offering multiple specialized performance characteristics, providing explicit evidence of product-development capability, although the extent to which this capability is directly held by Nanjing Rays is not fully specified.

Production capacityThe associated manufacturer is described as having more than 300 employees, two production bases, six workshops, more than 10 production lines, and an annual supply capacity of 10 million meters. Nanjing Rays itself is identified as a trading company with a listed plant area of 103.74 m², so the evidence supports access to substantial affiliated or source-manufacturer capacity but does not establish equivalent direct production ownership by the target entity.

Customization capabilityThe associated company is explicitly described as developing various non-standard special cables for users and providing technical solutions for transmission systems. This directly supports the availability of customized or application-specific cable solutions, though the responsible entity and implementation process are not fully detailed.

Product Q&A

Q:What is a mica cable?

Mica is a natural mineral with excellent insulating properties. It can resist extreme heat and does not catch fire easily. Mica insulated cables are built to endure temperatures as high as 1000C. They consist of mica tape wrapped around conductors to prevent electrical failures.

Q:What is mica in electrical?

Mica as an Insulation Material. The merits of mica as an insulation material in electrical engineering are a high dielectric strength as well as the stability of the dielectric strength at all electro technical occurring, relevant, temperatures.

Q:Is mica resistant to high-voltage?

Mica can withstand up to 2000 kilovolts per mm of material before breaking down. It can also withstand incredibly high temperatures (which obviously come hand-in-hand with high voltages). Pure mica can withstand up to 900C, and when reinforced and laminated with other materials can tolerate up to 1600C.
