Description：
As a pioneering original equipment manufacturer (OEM) in China’s recloser industry, we have accumulated decades of R&D expertise, taken the lead in establishing the original industry standards, built a fully independent end-to-end production system, and delivered reliable product solutions for power grid construction.
The RCW series automatic circuit reclosers can use on overhead distribution lines as well as distribution substation applications for all voltage classes at 50/60Hz power system. and it’s rated current can reach 1250A.The RCW series automatic circuit reclosers integrates the functions ofcontrol, protection, measurement, communication, fault detection, on-linemonitoring of closing or opening.The RCW series vacuum recloser is mainly combined with integration terminal, current transformer, permanent magnetic actuator and it’s recloser controller.
Features：
Automatic Fault Isolation: Accurately identifies and isolates permanent faults within milliseconds, reducing outage scope by over 85%.
Automatic Service Restoration: Restores power to non-faulted sections within 2 seconds via intelligent topology reconfiguration, ensuring continuous operation of critical loads.
Fault Detection and Protection: Employs high-frequency transient recording and AI diagnostics to accurately identify 32 types of fault characteristics, enabling adaptive protection.
Sectionalizing Protection: Supports four-level grading coordination and virtual segmentation with ±10ms timing accuracy, eliminating the need for additional physical switches.
High Reliability and Durability: Core components are validated for 100,000 mechanical operations, featuring wide-temperature operation (-40°C to 75°C) and IP68 protection rating.
Environmentally Friendly: Utilizes vacuum arc-extinguishing technology with zero SF6 gas usage,
