The universal sealing system for cable ducts, cable service entries with
extended range of temperature -30°C to +45°C (short-term +70°C/4h).
Predestined in the field of power cables.
For duct ID Ø 40 - 300 mm.
For installations in running or standing water and
4 x usable.
ZKAK/V sealing elements with a valve are reusable seals (Fibre Optics CT patent, registered under EP 17972224.3) with a cellular rubber coating, equivalent to the coating with swelling material (QAK/V-L), which has had undiminished success for many years on the market.
Application-specific requirements, such as installation under running or standing water, created the need for the new technology with cellular rubber.
The sealing element (valve) fulfils the requirements of the T-Com TS 0307/96
(Approval No. Wolf 2005-08-11 ADE 100 (valve)).
Wolf sealing elements provide the user with a durable, reliable seal in a temperature range
-30 °C to +45 °C (+70 °C for a short period of 4h).
Sealing cushion materials:
The flat tube cushion is made of a five-layered aluminium laminate.
The high quality of both material and processing guarantees a very low diffusion/leak rate of ~ 0.73 mbarl / year and ensures a long service life.
The filling unit:
In order to be able to fill the sealing cushion several times (4 times), a patented metal air valve with a plastic-coated valve extension is connected to the sealing cushion by means of a heat-seal welding process.
The pressure is filled via a pressure hose, which is plugged onto the sealing cushion to fill the car valve. After the pressure has been filled, the valve is sealed pressure-tight with the valve cap.
Tight against gas diffusion, dust, water (5 m water column) and chemical mixtures
