Home / Steel cable trays for nuclear power plants
In case of horizontal cable trays, the trays are supported by cantilevers clamped to standard struits with e. Nova, a product and service brand of Curtiss-Wright Nuclear, supplies safety-related cable tray systems that are manufactured to current NEMA VE1 specifications to the nuclear industry and other power generation industries. The cable tray structure comprises a support column (5), a flexible cable arrangement device (6), a cable connecting plate (8), a cable tray (9), a guide rail structure (10), a tray moving limit.
In a nuclear power plant cables supported on the cable trays may be related to safety functions, control systems, power input etc. Such cable trays must be capable of withstanding
