What safety precautions are required for installation?

The assembly must be used in series with an isolation link or current-limiting fuse to prevent high current faults close-in, even after the fuse link has been replaced.

AI-Powered supplier vetting

SummaryThe supplier is identified as Starrysky Industrial (Shanghai) Co., Ltd., a China-based limited company described as both a trading company and manufacturer/factory. The available evidence shows OEM and ODM capability, full customization, 3D design services, recent new-product activity, raw-material traceability, and 100% finished-product inspection. It offers overseas service through agents or branches and provides debugging and maintenance services in India, but has no overseas warehouse or showroom and no recorded offline trade-show participation. Service procedures exist for supplier assessment, corrective actions, and complaints, yet written records are absent. Financial information is limited to year labels rather than performance figures, so financial credibility cannot be assessed. No certification information is provided. Customer references are limited to a separate company description stating service to more than 200 worldwide customers, and the relationship to the named supplier is not...

Product Q&A

Q:What are the available voltage ratings?

The assemblies are available in two sizes: one suitable for 8.3-23 kV applications and another for 23-38 kV applications.

Q:How does the flapper valve enhance safety?

The optional flapper valve closes when the fuse holder is removed, minimizing oil spillage, reducing environmental concerns, and protecting line personnel during fuse changeouts.

Q:Can these assemblies be used for loadbreak operations?

Yes, when typical safety practices are followed, the assemblies can be loadbreak operated for working on the transformer secondary, changing distribution voltage, or disconnecting the apparatus.

Q:What type of transformers are these compatible with?

They are designed for use in pad-mounted or subsurface distribution transformers filled with Envirotemp FR3 fluid, transformer oil, or approved equivalents.

Q:Are silver-plated options available?

Yes, Silver-Plated Flapper Bay-O-Net assemblies are available and recommended for use with high ampere overload Bay-O-Net links to handle larger kVA transformers.
