3 Presentation Overview KJA0072 Pole mounted switch disconnectors for demanding outdoor environment General description We believe that flexible solutions and competent support are key elements for your continued success. Schneider Electric develops and supplies solutions finely tuned to user requirements and standards. The pole mounted FLUSARC family is the right solution in operation everywhere in Medium Voltage Networks. Example of FLUSARC P-LA installation Features The pole-mounted FLUSARC are switch-disconnectors insulated in SF6, reliable for outdoor use. They can be connected to aerial lines. Welding of components is carried out through the method called TIG, which consists in melting the edges to be joined without weld material. The external operating mechanism is very simple and reliable, since it is of the type with independent operation on exceeding dead center; the contact operating shaft rotates on bearings housed in a stainless steel box, which guarantees long endurance. Indication of the contact position (open/closed) and SF6 gas pressure are visible at the foot of the pole through two inspection windows located under the operating mechanism protection. The operating mechanism cover is steel made, properly worked and painted in order to withstand atmospheric agents. Main advantages Advanced insulation materials; Stainless steel tank containing all the live parts and switching functions; Improved safety for both operating personnel and the public. Customer benefits Uneffected by any climatic condition; Ideal for all pole type; Maximum service reliability; Easy inspection and maintenance; Easy installation and connection. 3

6 Product description General KJA0051 FLUSARC P-LA Aerial line connection insulator 2. Inox AISI 304 stainless steel enclosure 3. Operating mechanism cover 4. Safety valve located in the rear side of the enclosure 5. Contacts position inspection windows 6. Open/close operating lever 7. External cone disconnectable socket The pole-mounted FLUSARC P-LA enclosure is made of stainless steel AISI 304. It has an IP67 protection degree. The operating mechanism protection frame is also made with stainless steel with IP54 protection degree. The SF6 gas pressure inside the enclosure is 0.3 bar relative at 20 C. The pole-mounted FLUSARC are manufactured with horizontal translation contacts with selfblasting operation which enable electric arc extinction. The bushing insulator connections are of silverplated copper. The contacts support and bushing insulators are of epoxy resin, filled with quartz so they are resistant to ultraviolet solar rays. The FLUSARC P-LA switchdisconnectors are constructed with non-toxic material and are completely retrievable; for this reason it is possible to recycle 80% of the material used at the end of their working life. KJA0058 Connections The electrical connections to the main circuit are achieved by external cone disconnectable sockets (connections which are in accordance with EN type C interface standards). 2 1 Installation The pole-mounted FLUSARC P-LA switches can be horizontally assembled at different height from ground and can be operated in full safety either on poles or on towers with operating rods or hot sticks. The pole (2) assembly is performed by means of an horizontal switch support (1) and a strip (3). KJA Pressure gauge On request it is possible to apply a pressure gauge to check SF6 pressure outside the switchboard, protected by a hood. The rated pressure is 130 kpa absolute at 20 C. 6

11 KJA0303 General Ecological considerations The switch disconnector satisfies to a high degree the ecological requirements in respect of environmental protection thanks to optimization of material and energy consumption during manufacture compliance with all ecological requirements during its service life the use of recyclable materials for efficient disposal at the end of its service life. Our design directive regarding environmentally compatible design specifies the use of materials which can be dismantled and are easily recyclable. The metals which form approximately 90% of the switch disconnector are easily recyclable. They can be 100% recycled as new metal components at the end of their service life. Disposal valve Plastics can also be recycled. The thermosetting plastics can be fragmented and reused as fillers in other plastic components; the thermoplastic materials can be recycled in new plastic components. This means that the material is recovered, processed and reused in the manufacture of new parts. To ensure efficient and environmentally friendly dismantling and sorting of materials by responsible disposal experts, all plastic components are identified accordingly. Moreover, material and utilization data sheets are available to provide the customer with an overview about the materials used, and the disposal company with important information regarding the recycling process. Thus, the materials used for our products can be 100% recycled. This provides a vital contribution to savings in global primary energy and material resources. All materials were selected and developed so that, for example, switch disconnector affected by a fire in a building would have a minimal effect on the fire load (heat development and pollutants in the emissions). Another important ecological aspect is the longevity of our products (approx. 30 years), which is an extremely long service life compared to other capital goods. Also, the FLUSARC P-LA switch disconnector units have been designed to require little maintenance, giving further energy and material savings, and to enable straightforward replacement of component parts, e.g. if new controllers have been developed (upgrading). The high-voltage conducting parts of our gas-insulated switch disconnector units are hermetically sealed in an insulating inert gas (sulphur hexafluoride SF6 which is neither reactive nor toxic). Thus, all environmental influences which could reduce the service life are kept outside. The particular characteristic of the insulating gas also enables the overall size to be decreased by approximately 30% compared to switch disconnector without insulating gas designed with equivalent technical characteristics. This again saves on material and saves on the energy required to produce the material. The amount of insulating gas used in FLUSARC P-LA is approx. 0.5% of the total weight of the switch disconnector. Once the switch disconnector s service life has ended, the gas can be completely extracted via the disposal valve provided in each gas-filled compartment, and then recycled. To this end, the gas suppliers have developed an efficient recycling method. In normal operation, the gas need never be replenished during the entire service life. The switch disconnector has been designed as a hermetically sealed pressure system according to IEC and EN

16 Shipping FLUSARC P-LA Packing Strictly observe the symbols and the instructions indicated on the packing. The FLUSARC P-LA switch disconnectors are usually packed either inside a cardboard box or in a wooden case and firmly fastened at the base of a wooden pallet, but they can also be packed with other methods, according with the shipment and storing requirements and complying with the Customer requests. The apparatuses are protected by polystyrene foam panels and wrapped in a waterproof plastic housing, in order to prevent any water infiltrations during the loading and unloading phases and to protect them from the dust during storage. Leave the equipment in its original packaging during storage. If units or parts are unpacked for checking, they must be repacked for continued storage, using the original packaging. Avoid condensation. Transport The motor vehicle used for the transport must be equipped with the loading platform realized in an anti-slip material with a high friction coefficient. The switch disconnector must be positioned on the loading platform transversally back to back, by interposing materials fit for absorbing the compressions and for eliminating any possible direct contact of the surfaces of the different apparatuses. On the loading platform, purposed longitudinal members must be disposed, in order to space every switch disconnector and to prevent both its longitudinal and its transversal shifting. The different switch disconnector must be anchored to the motor vehicle structure by means of ropes, in order not to provoke deformations and to prevent their possible turnover on curves or in case of a sudden braking. Besides, the motor vehicle used for the transport must be equipped with a covering sheet. LOA4400 Handling During the switch disconnector handling, it is recommended not to stress the possible cables connection bushings placed outside.
