Medium-voltage disconnector FTr 27.5-2000-1B

single-poleACfor railway applications

These Driescher outdoor switches are specially designed for railway applications. They meet the specifications according to the EN 50152-2. The 1-pole and 2-pole switches are designed for a rated voltage range from 15 kV to 29 kV and a rated current range of 630 A and 2000 A. Design The live parts are in silver-plated copper with galvanization according QTL 0200. All steel parts are hot galvanized. Upon special request an additional coating of paint (RAL 7033) is available. There is increased resistance against corrosion through the use of non-rusting materials and surface protective coating. Each switchgear is fitted with an earth connector screw. Optionally a fixed earthing switch can be mounted. Design of switch The types of outdoor switch-disconnector and outdoor disconnecting switch mostly differ through the application of different cast-resin insulators (length and height of creepage path) as well as in the baseframes (U-profile and sheet-metal frame). Optionally its possible to equip the switches with, silicon combined insulators.
