CFS-T cable transit system

One system – a host of advantages

Designed as a modular system, the Hilti Cable Transit System solves three problems simultaneously. These versatile sets consisting of the fire-resistant, gas- and watertight basic module, module adapter and core module not only seal around cables quickly and reliably, they’re also re-usable. That saves time, cuts costs and helps keep your inventory to a minimum.

Cable Module

Basic module
The basic module for sealing around cables to a tolerance of 2-3 mm (without use of an adapter). The modules are supplied in a joined-together state but can be easily separated for individual use. Available in 7 different module sizes (15, 20, 30, 40, 60, 90 and 120mm).

Adapter module
Adapter modules in black or gray for sealing around cables to a tolerance of 3-5 mm.

Core module
The core module is used as a filler where space is reserved for future cable installations.

Filler Module

Space reserved for future cable installations can be filled with the filler modules in the sizes 5, 10, 15, 20 and 30mm. The filler modules are supplied in a joined together state (filler module blocks) but can be easily separated for individual use.

Wedge compression kit

The CFS-T WD 120 wedge compression kit is used to allow quick and easy compression of modules and filler blocks for an effective seal. The sealing wedge can be placed anywhere within the frame and there is only one central bolt to be tightened. Available with bolt and counter-plate made from galvanized steel or A4 stainless steel material 1.4571 (AISI 316Ti). The CFS-T WD 120 wedge compression kit is supplied complete with 4 anchor plates, one fixing anchor plate and lubricant (30 g).

Anchor plate

The anchor plate facilitates assembly of the cable modules and filler modules, secures these within the frame and increases tightness of the seal against static and dynamic pressure. The anchor plate is available in galvanized steel, stainless steel material 1.4301 (AISI 304) or in aluminium. Use one anchor plate between each row of modules and also to secure the CFS-T WD 120 wedge.

Fixing anchor plate

The fixing anchor plate is used in conjunction with the module squeezer. After precompression of the modules, the fixing anchor plate can be secured by tightening the screws against the frame. It thus holds the rows of modules in their precompressed position. This facilitates insertion of the last module and the wedge seal. Use of the fixing anchor plate is recommended in situations where a large number of cables pass through the transit frame.

Module squeezer

The module squeezer uses the screw jack principle to achieve easy precompression of the modules before insertion of the row, or last two rows, and thus facilitates further assembly of the cable modules and insertion of the wedge seal.

Wedge puller

The wedge puller is used as a disassembly tool to aid removal of the CFS-T WD 120 wedge seal without damage to allow subsequent retrofitting of additional cables.
