HAWKE LUBRICANT TRANSIT SYSTEM
The 967 Silicone Lubricant is use to aid the installation of blocks which are tightly fitted.
The silicone remains soft a low temperatures and will not dry out over long periods of time ensuring that future modifications to the transit will not be impeded.
Hawke recommends 1 our Lubricant Ref.967 for each 3 apertures.
Lubricants are to be used in all installations to assure the proper sealing performance. Lubricant is a kind of animal grease, which is natural and non-corrosive. It is applied to the surface of modules，Clamping device, internal walls of frames, and separating boards, to not only lubricate the surface but improve insulation performance of transits as well..
Hawke Transit System – HTS is a manufacturer of cable and pipe modular sealing systems.
The company has over 30 years experience in product development, system design, supply and installation and has supplied major projects in a variety of industries around the world.
The Hawke Transit System was first developed over 25 years ago to meet the harsh and hazardous demands of the North Sea Oil Industry. It has since developed for use in many diverse industries.
As a fire barrier it is a means to maintain the integrity of a firewall, bulkhead or deck through which cables, pipes and other services pass. It will also seal against and exhibit resistance to: water, gas, smoke, vermin, radiation,chemicals, explosion, UV Light, EMC and it also exhibits noise attenuation properties.
The Hawke Transit System is the most user friendly modular sealing device on the market. It also boasts the best system compression.
It does not need any on-site modifications. The cable blocks incorporate a colour coding system to minimize incorrect installation.
The cable blocks have five sealing faces so that the best possible grip is achieved.
The cable range is also marked on the blocks to aid with on-site inspect-ability.
Fireproof and watertight transit system HAWKE International
HAWKE transit system was developed for applications with great emphasis on security and protection of cables and is capable of resisting these influences and environments:
The most common HAWKE transit system in telecommunications, military industry, construction of tunnels, construction of shopping centres, nuclear power plants, hydro power plants, chemical industry, pharmaceutical industry and the marine industry.
Round transit frame, which is supplied in
types 30,40,50,70,100,150 and 200mm.
It is suitable for usage in round holes,
where sealing is done by tightening nuts
around the perimeter of the head plate.
The metallic head and rear plates at the
same time pull and push the middle black
rubber ring, thus sealing the assembly
hole in the wall. At the same time, the
cable modules are pushed to the centre of
the passage and thus to overall sealing of
the entire cable passage.
| Type: HMX
The steel ring of the cable passage for the version for welding to the wall or
passage. This type of frame is suitable for applications such as containers,
steel constructions, marine industry, tanks, etc. Assembly is done by installation
of the largest cable sizes and appropriate modules, such that we start from the
lower modules upwards. Between each module layer, a spacing plate is
installed to facilitate error-free installation during the pushing process. Naturally,
each layer must be fitted with the same outer module diameter so that
assembly can be done. At the end, the compression wedge that seals the
passage is fitted.
| Type: HCX
This type of frame is intended for wall up or bolting. These passages are the
most common and are intended mainly for the building industry and
telecommunications. The standard design is steel; upon request stainless
steel frames are supplied. The assembly procedure for the interior is the same
as applies to type HMX; the frame as such can be walled up or bolted. In the
case of this frame, it is necessary to apply intumescent mastic between the
wall and the frame so that we eliminate eventual unevenness between the two
surfaces and prevent eventual penetration of water or humidity.
| This type of frame is suitable for installation of new cables or ducts.
This type of divided frame can be used for already existing cable installations, or
ducts for additional sealing of the passages without any necessity to remove
already installed cables.
For installation of more demanding cable passages with a larger number of
cables, or necessity to separate certain cable bunches, it is possible to use
| For the inner space of the frame and cable
installations, typical module series are
used whereby each module offers a range
of 3mm for the cable size. Both halves of
the module are colour-coded for better
If in the design of cable passages and, eventually, reserves for planned future
cables, you need to fill a place in the passage, we use sealing modules, which
are in the same type series as the cable modules. Again, it must have the same
outer dimensions as the cable modules.
| For installation of type HMX A HCX frames, we need a compression system. The
compression system can be collapsed into 3 components, such that it is easy
to insert two outer parts of the compression system into the compressed
installed module with an compression tool, after which the compression tool is
released and the third, middle part of the compression system is inserted. After
this, the 3 nuts on the compression system are tightened and perfectly press all
the installed modules, thus sealing the cable transit.
| For error-free assembly of the transit, it is essential before installation of the
modules to slide out the last layer of the frame with the pressure plate of the
compression system, install the rest of the modules (at this stage, the limiting
plate is no longer used) and the assembly wedge is fitted at the centre, which
upon tightening acts as a jack. We compress the modules of the frame in such
a way that it is possible to insert the two side parts of the compression system
along the sides of the assembly wedge.
| In case of dismounting of the HMX and HCX frame, it is necessary to use a
pulling element, which acts as a puller. Without this puller, it is not possible to
remove the centre piece of the compression system, even when you loosen the
nuts. It is only after removing the centre piece of the compression system using
this puller, that you can slide the compression tool into the created gap, you
press the modules in such a way that it is possible to also remove both side
pieces of the compression system and then release the compression tool and
remove it from the frame. After this, you can easily make adjustments without
The stayplate is inserted between each module layer, excluding the top layer.
The function of the plate is important, because it ensures proper pushing of the
modules over the entire width of the layer and the transit is thus perfectly sealed.
Lubrication gel is an important and essential component of the cable.transit. it is
necessary to lubricate all the inner parts of the frame and modules used in
assembly because this guarantees faultless positioning of all assembly
components of the passage and hence perfect sealing of all the transiting
cables or ducts.
| Intumescent mastic is used in the assembly of the HCX. frame The caused is
applied between the wall and the border of the frame, thus leading to sealing of
any eventual gaps (caused by wall surface unevenness) between the frame and
the wall and thus prevents eventual penetration of water or humidity into the
