Mobile elevating working platform (MEWP) for live working on VHV sub-stations (Sub-station LW MEWP)

Abstract

France and more particularly RTE (Réseau Transport Electricité) is a pioneer in carrying out LW work in very high voltage sub-stations (225 kV and 400 kV). In the 1980s, SERECT, the RTE centre of expertise for live working, developed an Insulating Positioning Tower (IPT) to be able to carry out bare-hand live working in these sub-stations. Although the IPT was a revolution in its day, today it no longer meets the company's needs completely: neither in terms of ergonomics (climbing, access), nor in terms of design (tedious assembly), nor in terms of technology (silicone treatment, restricted use in a damp environment). With the benefit of these observations, SERECT has worked with France Elévateur to develop a Mobile Elevating Work Platforms for live working in very high voltage sub-stations (Sub-station LW MEWP). This MEWP uses the latest technologies. Ergonomics of the workstation are improved. It can be moved and positioned more rapidly and more precisely. The machinery is equipped with an insulating boom with fins, ready to be used; no assembly, no drying and no silicone treatment before starting work.
