GENERAL FEATURES SKEMA HAS BEEN AT THE FORE- FRONT OF INNOVATIVE LOW VOLTAGE SWITCHGEAR SYSTEMS FOR OVER 40 YEARS. THROUGH OUR COMMIT- MENT TO THE HIGHEST STANDARDS OF PRODUCT DEVELOPMENT, MAN- UFACTURING, TESTING AND AFTER- SALES SUPPORT, OUR CUSTOMERS HAVE FOUND THAT PARTNERING WITH SKEMA PROVIDES THEM WITH UNRI- VALLED SERVICE, RELIABILITY AND PEACE OF MIND. Skema s IN-CHARGE switchgear is a flexible modular system offering both fixed and withdrawable configurations for powering, controlling and protecting low voltage feeders and motors. It is particularly suited to applications that demand high levels of performance and reliability, and thanks to its versatility, it can easily be adapted to suit any plant configuration, electrical layout or onsite installation requirement. The wide range of sections and the availability of different versions (affording both front and rear access, top or bottom cable entry) allow Skema s IN-CHARGE switchgear to offer solutions with a view to satisfying any set of requirements in terms of installation and space. Switching operations, as well as access and routine maintenance, can be carried out without compromising the safety of personnel and without any danger of accidental contact with live parts. APPLICATIONS Thanks to its versatility and integrity, Skema s IN-CHARGE switchgear can be utilized in any Oil & Gas/petrochemical application including onshore, offshore platforms, FPSO, FLNG, power generation plants or industrial plants, or wherever the following characteristics are essential: > > Personnel safety > > Flexibility and continuity of service > > Reliability > > Low level of maintenance > > Easy installation and connection > > Possibility for extensions and modifications > > Integration with upstream control and monitoring systems CERTIFICATES AND TESTS > > Main standards: IEC 61439, IEC 61641, IEC 60529, IEC 60255 > > Designed for safety, fully verified assemblies to IEC 61439 > > Internal Arc Containment (IAC) tested to IEC 61641 > > Tested for seismic load to IEC 60068-3-3 > > Vibration tested to IEC 60068-2-6 FEATURES AND BENEFITS > > Modular and compact, space-saving design, easy assembly and safe onsite cubicle reconfiguration without de-energising the busbar > > Suitable for all Power Distribution and Motor Control applications > > Seamless integration with upstream control and monitoring systems > > Quick and easy installation > > Focus on quality, safety and reliability > > Flexibility during the design phase and high level of versatility 06 07 > > Compliant with the most stringent Oil & Gas standards (Shell DEP)

BUSBAR SYSTEM MAIN BUSBARS > > Standard design ensures low probability of internal arc faults through the use of high-performance busbar supports and oversized creepage/clearance distances. Optional arc propagation barriers can be installed between cubicles to limit the spread of arcs in the unlikely event of an internal arc fault. Busbar systems have been arc fault containment tested in accordance with IEC 61641 > > Available in ratings up to 5000 A, 100 ka RMS fault withstand capability and 220 ka peak withstand capability > > All busbar are made from HDHC copper and can be finished in plain copper, tin-plated, silver-plated, nickel-plated or fully insulated 10 11 MCC RISER BUSBARS > > HDHC copper riser bars are round in cross section for high through fault withstand capability and are tin-plated for low contact resistance plus high mechanical endurance at the connection point of withdrawable chassis > > An IP2X insulated barrier segregates the riser bar from the MCC equipment bay and allows connection to the riser bar at 76 mm intervals > > Optional IP4X lockable automatic shutters can be fitted for enhanced segregation and safety > > Standard riser bars have been arc fault containment tested in accordance with IEC 61641 and are designated as an arc proof zone
