    3 – Mechanical synoptic state of circuit breaker 5. SF6 SYSTEM The ISF switches and SF isolators, of insulation in SF6, used in the NORMAFIX cells are devices that are watertight and sealed for life (according to IEC 62271). The tightness of this equipment is guaranteed by routine tests performed. The expected life of this equipment is 30 years.

  • Page 14: Dispatch

    6. DISPATCH The NORMAFIX cells are shipped with the switch open and the earthing switch closed. The NORMAFIX cells are shipped individually on a wooden pallet (fixed by four screws and covered with transparent plastic film). Accessories for mounting and wiring of the cells are supplied separately.

  • Page 15: Installation

    NORMAFIX The panels should be stored with its original packaging, to avoid dust, splashing water and chemicals, in a well ventilated and dry area, at a temperature between -25°C and +40°C. 8. INSTALLATION 8.1 Preparing the floor The floor maximum admissible unevenness is of 2 mm/m in order to allow an easy mounting and a good final appearance of the panels set.
