KES cable entry systems Over the course of its life, a building frequently undergoes renovation or refurbishment. In most cases, however, these activities only take place in the parts of the building located above ground level. Nonetheless, the requirements for the cable infrastructure in a building can also change significantly over time. This is where it is recommended during construction of a building to provide for spare openings and lay a robust, durable empty conduit route via which lines can be replaced or new lines laid without having to dig up the entire conduit route every time. For this purpose, Hauff-Technik offers the KES150 pressure-tight cable entry system, which is compatible with the Hateflex14150 and Hauff-Flex 150 spiral hoses, as well as various options for cable sealing. This system can be relied upon to provide optimum protection for the cables that are being laid. The main areas of application for pressure-tight cable entry systems are building entries, substations, converter stations or cable shafts
