On each of the two exposed block faces minimum and maximum diameters are clearly marked. This indicates the specific sealing range of the block size.
Each individual block has a colour coded face, this ensures that each size and pair of tolerant block halves is always correctly matched to the cable diameter. Hawke´s unique inspectable colour coded blocks ensure that the top and bottom half of each block has been correctly matched for size.
Hawke cable/pipe tolerant blocks have been designed with a degree of flexibility in order to accommodate variances in cable diameters. Additionally this flexibility enables each Hawke block size to accept a range of cable or pipe diameters.
Available in seven block sizes accomodating service diameters from 3 mm to 100 mm, Hawke Blocks are marked with minimum and maximum cable diameters e.g. block size to accept cable diameters from 18 mm up to maximum of 21 mm.
In practise this means that a small number of blocks can accomodate the full range of standard cable sizes. There is less inventory to manage and the installation procedure is much faster and simpler than competing systems.
Hawke Blank Filler Blocks
Filler blocks are available in the same materials as the tolerant Blocks. They are used to fill spaces within the frame which are not required for services, thus allowing spare capacity for future requirements.
Hawke Standard Tolerant Blocks
This enables a wide range of cable or pipe diameters to be accommodated by a compact range of tolerant block sizes.
Hawke tolerant blocks have five sealing faces that are displaced by the sealing process. This results in a tolerance of up to 4 mm for cable diameters.
Hawke Trefoil Insert Blocks
These blocks allow three single phase power cables to be sealed inside of the same cable block.
*Available in 90mm and 120 mm size*
Hawke Special Insert Blocks
Hawke manufacture a range of blocks to suit the most popular waveguide sizes
(For services that are shaped anything other than circular e.g. busbars, earthstraps, etc).
Hawke Design Software calculates the best frame and all the possible options. It let you modify the input data and recalculate again automatically, saving many time. The layout preview facilitates the installation showing the colour coded blocks.
ISO Certified and Testing Facilities
Hawke Transit System-HTS is credited by Lloyd's Register LRQA according to UNE-EN-ISO 9001:2000 and complies with the European Directive of Marine Equipment MED 96/98/EC, for the production of the sealing blocks under the modules B+D.QA SYSTEM
