Product Description
Product Description
iSafering SF6 insulated Ring Main Unit
Gas Insulated Ring Main Unit
iSafeRing is a SF6 insulated ring main unit for the secondary distribution network. iSafeRing can be supplied in 10 different configurations suitable for most switching applications in 12/24/36 kV distribution networks. As an option, iSafeRing can be delivered as extendable ring main unit.
Together, iSafeRing represent a complete solution for 12/24/36 kV secondary distribution networks.
Modularity and external busbar
All modules except the metering module and circuit-breaker module are only 325 mm wide.
Transformer protection
iSafering offers a choice between a switch fuse combination and circuit breaker with relay for transformer protection. The switch fuse combination offers optimal protection against short-circuits, while the circuit breaker with relay option offers better protection against low overcurrents. Circuit breaker with relay is always recommended for larger transformers.
Normal operation conditions
The rated characteristics of the switchgear are valid under the following ambient conditions:
minimum ambient temperature: - 25 °C
maximum ambient temperature: + 40 °C
For different temperature ranges, please contact your UNISUN sales representative.
Standards
iSafeRing/iSafePlus is tested according to following
IEC-standards:
IEC 62271-1/IEC 62271-100/IEC 62271-102/IEC 62271-103/IEC 62271-105/IEC 62271-200/IEC 60529:
