13.8‑36 kV pole‑mounted smart line sectionalizer, 400A rated continuous current, adjustable fault‑count 1‑3, vacuum/SF6 interrupting, IP65 RTU, multi‑protocol communication & cyber‑security functions for 60 Hz overhead distribution‑network.
This PDF is SEC’s utility‑grade technical specification for pole‑mounted smart line sectionalizer, for EPCs, bidders and design institutes for tender submission, gap analysis and pre‑award review. It follows IEC 62271‑103, ANSI C37.63, IEC 60870‑5, IEC 61850 and SEC requirements.
Ratings: 13.8‑36 kV, 400A continuous current, 10kA‑3s short‑time withstand; adjustable 16‑640A phase‑fault, 3.5‑320A earth‑fault, 1‑3 configurable trip counts. Equipped with vacuum/SF6 interruption, sealed stainless‑steel tank, anti‑bird polymer bushings and IP65 tropical‑rated RTU.
The RTU supports local HMI, laptop setup and SCADA remote control with multi‑protocols, diverse transmission media and full cyber‑security features. Integrated dry‑type VT/CT; maintenance‑free backup battery provides ≥10‑hour operation and 8 switch cycles during AC power loss.
This spec covers bilingual weather‑proof marking, type/routine/sample tests, 5‑year warranty, spare‑parts, on‑site training and tender deliverables. Parameter tuning, accessory adaptation and project‑specific FAT are available for hot‑climate overhead distribution projects. Contact us for compliance templates and complete qualification documents.
