Over the years, Sécheron has developed an impressive portfolio of components and platforms for high voltage solutions. These cover most of the needs for AC rail vehicles, regardless of where these components are installed, on the roof, under the vehicle’s frame or inside the vehicle.
Today, Sécheron delivers the most complete range of roof-installed high voltage individual components and integrated solutions. These cover the requirements and constraints of almost all vehicles.
The AC MODFRAME is an integrated solution developed for AC and AC/DC Electrical Multiple Units (EMU). It integrates most of the high voltage roof components required for the operation and protection of AC rail vehicles on a single outdoor frame. The main components installed are from Sécheron’s range, supplemented by other devices from leading third party suppliers.
All components installed on the MODFRAME are connected together with busbars, cables and braids, offering the car builder a simple and easy interface for high voltage connections between the MODFRAME and the vehicle. Low voltage cables are directly connected to the individual components through easily accessible outdoor type low voltage connectors. The installation of the MODFRAME on the roof does not require any roof cut-out except if the manual operation is selected for the earthing device.
The frame is made of painted structural steel, designed and manufactured according to EN 15085 standards in our highly certified welding factor. It is designed according to EN 12663 standards for for the structural requirements of railway vehicles. The customizable frame allows adaptation of the MODFRAME to different types of roof architecture and fixation.
The AC MODFRAME perfectly complements the AC MODBOX range where the same type of high voltage components can be integrated horizontally in a compact aluminium enclosure for installation on high speed trains and rail vehicles with a restricted roof gauge, or vehicles operated in harsh environmental conditions.
