45
Rapier GX Load Break Switch- Benefits
• Field proven LBS performance• Low capital and lifetime costs• Virtually maintenance free• Designed for maximum operator safety• Capable of live line installation• Integrated solution for distribution automation
46
Rapier Overhead Range
Rapier RX - based on air break technology
• RX-M (manual down pole or hook-stick operation)
• RX-RC (local/ remote control via Gemini-RTU)
• RX-FS or Fuse Switch
47
Problems Associated withOlder Air Break Designs
• Mechanisms would seize up over time due to stiff bearings and corroded main contacts
• Load Break Heads seized up due to complex design
• Braided flexes and joints suffered corrosion
• Significant maintenance over the switches’ lifecycle
48
New Features in RX Design
• Low friction, corrosion resistant bearing leading to low maintenance and improved reliability
• Laminated flexes with no corrosive effects. (Tested for 2,000 operations before single lamination broke)
• New simpler design of Arc Chute device for rapid arc extinction when load breaking
• New tungsten tipped contacts so that Fault Make Heads can be fitted as an option
• All key components now stainless steel for corrosion resistance

Modular Design Approach
Switches can be specified with:
• FMH, LBH or EB• Current ratings of 400, 630 or 800A• Short circuit ratings up to 25kA for 3 seconds• Choice of insulators - traditional ceramic or
polymeric options such as EPDM and Silicone Rubber
• Manual or motorised mechanism• Remotely controlled with RTU and integral
motorised actuator
53
Patented Fault Passage Indicator
FPI
54
Why consider an RX switch as part of your DA?
• Much improved design so that the RX can be relied upon to be remotely controlled
• Significant price differential with SF6 enclosed switches e.g. £1,000 - £1,500
• No monitoring of SF6 gas pressure
• RX switch considered as a Point of Isolation
• Environmentally friendly “AIR BREAK TECHNOLOGY”
55

Gemini-RTU (host port) DNP3• Communications
Low power radio or GSM predominately
NB• Gemini-DC will reside mainly in primary substations
adjacent to primary RTU• Intermediate node acts as a Store/ Forward of
messages to other RTUs. This provides greater transmission coverage
