UNRI- VALLED SERVICE, RELIABILITY AND PEACE OF MIND.

4 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 > > Designed for safety, fully verified assemblies to IEC > > Internal Arc Containment (IAC) tested to IEC > > Tested for seismic load to IEC > > Vibration tested to IEC 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 > > Compliant with the most stringent Oil & Gas standards (Shell DEP)
