Busbar system with ERIP-insulation for low voltage for very high degree of protection
The ISOBUS LR system provides a value added solution for low voltage projects 3.6kV and 7000A per phase. It is an ERIP, fully insulated busbar system which provides a very high degree of protection.
The basic design, materials and components, manufacture, testing and delivery are the same as for ISOBUS MR. There is only one difference between both systems: ISOBUS LR has no capacitive grading embedded through the insulation layer. It is safe, compact, space and weight saving, virtually maintenance free with a very long lifespan.
< 3,6 kV AC, -7000 A
Degree of protection
IP30-IP54 inndoor, IP 54-IP67 outdoor, No. of phases: 2,3,4,5
Single phase segregated
Low Voltage Application
Harsh aggressive environmental conditions, e.g. power projects situated in extreme ambient temperature conditions, desert, arctic, tropical or underground
Offshore and Marine
Offshore wind-park substations
Up to IP 68 degree of protection available and type tested
Low voltage projects where space is limited
Low voltage projects where weight saving is necessary
Safety and Reliability
Touch safe under operational conditions due to embedded concentric earth layer.
Partial discharge free according to IEC 60 137 due to void free manufacture and routine testing of each section prior to delivery.
No phase to phase short circuit due to complete encapsulation and insulation of each phase.
Insulation withstand is E-120
High peak current withstand
Easily withstands ambient temperatures from below -50°C to above + 55°C
No halogens. If a fire occurs, no toxic gases develop and the insulation is self-extinguishing
Space and Time Saving Installation
Value added solution supplied. Both ISOBUS LR & its fixing system are designed, manufactured, tested and delivered as a low voltage distribution kit, complete with all components and installation documents
Modular system components allow made-to-measure distribution solutions within low voltage applications. Any three dimensional shape is possible
Compact outer dimensions, extremely small bending radii, and close phase to phase distance allow maximum power in minimum space
1 busbar per phase up to 7000A
Light weight system
Minimum impact in the surrounding building
Surrounding space can be dimensioned smaller
Busbar – Busbar connections
Same as ISOBUS MR, except that the connecting cylinders are air insulated metal.
Electro –Technical Equipment –ISOBUS LR Connections
As with ISOBUS MR, it is very easy to connect the ISOBUS LR system with all makes and types of electro - technical equipment available in today’s market:
Cnnections to flat terminals according to DIN 42206 or customer specifications
Plug-in connections to transformers or other equipment
Connections to every type of switchgear available on the market
