Document description

This is an installation drawing for the RWK-38 Line Sectionalizing Load Break Switch Controller.

ROCKWILL RWK-38 Line Sectionalizing Load Break Switch Controller is an outdoor intelligent sectionalizer control unit, designed for matching 38kV pole-mounted load break switches on overhead distribution feeders. The electrical drawing defines the complete internal wiring, signal loop, auxiliary power circuit, battery backup circuit, actuation output and communication terminal layout of the controller. It adopts loss-of-voltage and no-current sectionalizing logic, integrates high-precision voltage and current signal acquisition, fault counting, event 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-2025-04188, Witness Test Report No. WT-2025-09121, 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. With stainless steel IP65 tropicalised anti-corrosion and UV-proof enclosure, it adopts dual power supply design of external AC220V auxiliary power and built-in backup battery, suitable for long-term pole-mounted outdoor operation.

Frequently asked questions

What does the electrical drawing of the RWK-38 Line Sectionalizing Load Break Switch Controller cover?
