Our IEC61850 switches, integrating the IEEE1588v2 standard, Sync-E, full gigabit and both Layer 2 and Layer 3 availability, are specifically designed to operate reliably in power utility substations and climatically demanding industrial environments. They comply with IEC61850 and IEEE1613 standards. It supports many Layer 2 software features such as port, VLAN, multicast, QoS, fast redundant ring and Layer 3 features such as VRRP, RIP, OSFP, IGMP and PIM. At present, the product is widely used in intelligent substation and many other industrial communication systems.
