Auto Recloser Controllerelectrical drawing

Document description

This is an installation drawing for the RWK-35/65 Auto Recloser Controller.

ROCKWILL RWK-35/65 Auto Recloser Controller is an outdoor intelligent protection and control unit specially developed to match medium voltage pole-mounted vacuum auto reclosers. The electrical drawing defines the complete internal wiring, signal loop, auxiliary power circuit, backup battery circuit, switching actuation output and communication terminal layout of the controller. It integrates high-precision voltage and current signal sampling, phase overcurrent and earth fault protection, multi-shot programmable auto-reclose sequence, fault waveform recording, local HMI parameter setting and remote data transmission functions. The product complies with IEC 60255-1:2018, IEC 60255-26:2020 and IEC 62271-111:2019 standards. Relevant documents include Type Test Certificate No. TT-2025-04192, Witness Test Report No. WT-2025-09125, Routine Factory Test Report No. FT-2025 series, Raw Material Mill Certificates, all issued by CNAS accredited independent test laboratory and available for tender submission, utility review and project site acceptance. Adopting stainless steel IP65 tropicalised anti-corrosion and UV resistant enclosure, it supports dual power supply with external auxiliary power and built-in backup battery, suitable for long-term pole-mounted outdoor operation.
