Description

The RPS series outdoor pole-mounted SF6 load break switch is a fully gas-insulated AC high-voltage switching device specially developed for 40.5kV overhead power distribution networks. Rated at 630A, 50/60Hz, this product strictly complies with IEC and ANSI international standards, integrating compact mechanical design, superior insulation performance, intelligent secondary monitoring system and flexible customized manufacturing capability. It is applicable to pole-mounted outdoor deployment as well as substation indoor installation, delivering reliable, safe and low-maintenance switching solutions for medium-high voltage distribution systems.

Product Core Advantages

Ultra-Compact Mechanical Structure, Minimal Installation Footprint：The whole switch body adopts integrated sealed tank structure, with optimized layout of internal contact and operating mechanism. Compared with traditional air-type pole-mounted switches, it greatly reduces overall volume and occupied space. It adapts to narrow pole installation space and compact substation cabinet layout, lowering civil engineering and installation cost for customers.
Premium High-Grade Insulation & Stable SF6 Gas Insulation System：Fully sealed stainless steel tank filled with SF6 insulating gas, matched with high-performance outdoor composite polymer bushings. The product achieves high insulation withstand level, excellent anti-pollution, anti-condensation and anti-corrosion capacity, stable dielectric performance under harsh outdoor environments (heavy fog, salt mist, dust). Fully sealed gas chamber eliminates gas leakage risk in long-term operation, no regular gas refilling required.
Integrated Intelligent Secondary Control & Real-Time Monitoring Function：Equipped with complete intelligent secondary control module, supporting remote opening/closing control, real-time data collection including gas pressure monitoring, switch position status (ON/OFF mechanical indicator visible on front panel), fault signal feedback and communication linkage. It realizes unattended operation of distribution networks, compatible with mainstream distribution automation DTU/FTU systems.
