Abstract:
An electric multiple unit car-roof antifouling flash composite insulator comprising a support body (21) and several sets of sheds (22) provided around the sidewall of the support body (21) and arranged in parallel in the axial direction. The sheds (22) protrude in the radial direction from the sidewall of the support body (21). An upper metal fitting (23) is arranged at the upper extremity of the uppermost shed (22). A lower metal fitting (24) is arranged at the lower extremity of the lowermost shed (22). The creepage distance of the sheds between the upper fitting (23) and the lower fitting (24) is 1085 mm to 1095 mm. The arc-flash distance between the upper metal fitting (23) and the lower metal fitting (24) is 245 mm to 255 mm. The insulator employs a long creepage distance in terms of structural design, thus providing great antifouling flash capability, under same pollution conditions, provides great antifouling flash capability that is twice as great as that of a ceramic insulator having a same creepage distance, and is particularly suitable for use in areas having above-average pollutions.

Abstract:
The invention relates to an arrangement (3; 103) for drying air, particularly for a compressed air installation (4; 104) of a rail vehicle (1; 101), comprising an air dryer (12; 112) designed to be suitable for receiving air that is to be dried, via an air dryer inlet (17; 117). In order to optimise this arrangement with regard to external conditions prevailing in the region of a rail bound transportation route to be travelled, an air conditioning installation (5; 105) is provided that supplies air to an air conditioning installation outlet (8; 108), said air dryer inlet (17; 117) being connected, by means of an air channel (6; 106) particularly designed as an air conduit (6a, 6b; 106a, 106b), to the air conditioning installation outlet (8; 108) such that at least one portion of the air supplied from the air conditioning installation (5; 105) forms the air that is to be dried. The invention also relates to a rail vehicle (1; 101) that comprises such an arrangement, and to a method for drying air.
