 Insulated Busbar Systems

An alternative to parallel-connected cables, the busbar product group comprises a program of fully insulated bus systems of up to 245 kV and 8 kA.

The
DURESCA process is also considered to be a pioneer accomplishment in the field of solid insulation and is the product of 40 years of experience. Over the years, DURESCA has been adapted to the needs of modern energy technology. DURESCA solves space problems and is regarded as being especially safe and reliable. In 1990, the GASLINK SF6 bus system was developed by MGC in collaboration with a major customer to meet market demands and was approved for the market as an auxiliary product to the proven DURESCA
busbars. MGC offers extensive consultation for both systems, modern engineering and works testing. Assembly and start up, performed by MGC experts, is recommended. Products are manufactured by MGC Moser-Glaser (Switzerland) and sold by Global Power Partners LLC.  Products and their applications include: 

Duresca - 12kV to 170kV, and up to 8000A applications, insulated bus bar meant for switch-gear and transformer applications both indoor and outdoor. Ideally suited for climate challenged applications (marine or coastal systems, humid conditions, cold climates or contaminated conditions). With full insulation and ground protection surface, the reliability and safety of the bus bar format is improved, along with the ability to decrease size of the installations. Also allows the high voltage bus to be taken through walls and other barriers where fully insulated bus would provide advantages-thus reducing installation expense by eliminating the expense of wall bushings or insulators.  Many uses of the design found in the following  applications - Generating Stations, Medium and High Voltage Substations, On Board Ship Electrical Systems. 

Features: 

  • Solid, separately isolated phase bus, fully grounded for personal safety
  • Safe service connections, even in high ambient humidity
  • Partial discharge free operation
  • Compact dimensions, tight bend radii
  • Link between SF6 insulated and oil insulated equipment
  • Suitable for complete outdoor installation
  • Custom engineered for each individual installation
  • Operation by ambient temperature down to -40 degrees C (-50 degrees upon request)
  • No gas over pressure in the outdoor silicone rubber eliminates explosion danger
  • Ability to match with all types of GIS equipment
  • Factory tested
  • Easy installation

Tiresca - 15kV to 34.5kV with rated currents from 400A to 8500A, for substation bus connections for transformers to switchgear, and switchgear to switchgear. Intended for bus-bar connections in distribution substations or generation stations for partially insulated bus-bar applications.

Features:


  • Absolute safety against short circuits caused by small animals, branches, or metal part
  • Minimizing the distance betwen phase to phase and phase to earth
  • Adaptable system for all new and existing power plant installations
  • All busbars are insulated and tested in the factory
  • The system is UV radiation resistant and ensures constant protection against rough ambient conditions
  • The 2-part covering cap allows to check all electrical connections and joints
  • High leakage current and aging reistant by the corrugated synthetic protection tube
  • Expected lifetime >30 years  

 

Gas Link - Medium voltage applications to 40.5kV with up to 3150 Amperes with SF6 Gas to Air format allows easy  interfacing with GIS applications and indoor air portions of application. Medium voltage applications for GIS switchgear and substations.

Features:  

  • Protected against electrical shock hazards
  • Self-recombinating gas insulation
  • Additional fire protection not required
  • Simple fixation devices
  • Any connection to SF6, oil or air insulated, indoor or outdoor equipment possible
  • Nearly maintenance-free, long service intervals
  • Recycling of gas while dismounting
  • Short delivery periods due to the standardized elements
  • No deterioration, extremely short repair time in the event of fault
  • Suitable for operation under extreme service conditions
  • SF6 insulation test can be made without interrupting operation
  • Easy and quick assembly and erection due to pre-manufactured and pre-tested standard elements
  • Subsequent changes or extension of existing installation without difficulties
