What are the characteristics of ABB-SafeRing switchgear?

SafeRing and SafePlus switchgear for secondary distribution were developed by ABB in Skien and introduced to the markets in 2000, replacing the previous SF6-insulated products RGC and CTC.    The installed base of SafeRing/SafePlus is more    than 150,000 switchgears in more than 100 countries all over the world.

The switchgear portfolio is constantly under development to adjust to new market requirements and customers’ needs.

SafeRing is available in standard configurations based on a high-volume production. These

standardized RMUs, which are the most required configurations within a distribution network, can be extendable upon request.

Customer benefits

•  A widerange of functionalunits, easy to extend and upgrade
•  Up tofivemodules in one common gas tank
• Nolive parts exposed
• Fullysealed for lifetime
•  Climaticallyindependent
•  Designedandtested according to IEC
• Highreliability and safety
•  Compactdimensions
•  Safe and easy for operators inbothmaintenance and operating conditions
•  Alloperations are carriedout from the front of the switchgear
• Maintenance free

SafePlus is the switchgear version of SafeRing with flexibility, modularity and higher ratings.

Applicable standards

SafeRing/SafePlus is tested according to following IEC-standards:

•  IEC62271–1:Specifications High-voltage switchgear
• IEC62271-100: Alternating-current circuit-breakers
•  IEC 62271-102: Alternating current disconnectorsearthing switches
•  IEC62271-103:High-voltage switches
•  IEC62271-105:Switch-fuse co-operation
•  IEC62271-200: Arcfault and switchgear
•  IEC60529:Degrees of protection provided by enclosures

SafeRing/SafePlus is also tested together with  CSS according to IEC 62271-202 standard. Tests have been performed on CSS from various manufacturers.

Normal operation conditions

The rated characteristics of the switchgear are valid under the following ambient conditions:

•  minimumambient temperature:   –25°C
•  maximum ambient temperature:+40°C

For different temperature ranges, please contact your ABB sales representative.

Ambient humidity:

•  maximum 24h averageof relative humidity 95%
•  maximum 24h average of water vapourpressure 2.2 kPa
•  maximummonthly averageof relative humidity 90% RH
•  maximummonthly averageof water vapour pressure 1.8 kPa

The normal operational altitude is up to 1,500 m above sea level. For higher altitude applications, please contact your ABB sales representative.

The switchgear is designed for operation in normal, non-corrosive and uncontaminated atmosphere.
