PUK cable ladders can conduct cables with medium to large diameters safely along ceilings and walls. They are not only used in industrial plants and production halls but also in the construction of tunnels, power stations and plants. The large selection of materials and surface finishes means they can be used in a variety of ways, both indoors and outdoors. Cable ladders are an integrated, highly flexible cable support system when used in combination with the matching support structures, covers and system-specific accessories. They also allow a high level of air circulation, so that power cables can easily dissipate heat to the environment and heat build-up is avoided.
