The core of Habia Cable’s business is the design and manufacture of high specification, custom designed cables for demanding applications. Habia Cable’s ability to take many and varied components and combine them into a working, composite cable that is fit for function both electrically and mechanically is one of the best in the industry. Composite or multicore cables offer a key benefit in umbilical and reeling cables as a single composite cable can do the work of a strain cable, electrical cable, power cable and even a number of hydraulic hoses.
With a wide variety of sizes and impedances available, Habia Cable are able to combine any of the RG Style, Multibend, Speedflex or Speedfoam coaxes can be included within the design (Flexiform is not recommended for inclusion within composite cables due to its limited flex-life). Habia Cable is also frequently called upon to design customised coaxials for use within composite cables and these can be modified to feature varied impedances, additional screening or alternative sheaths and colours (including unsheathed coaxials).
As with the coaxial cables, data and ethernet pairs are available in a range of sizes and impedances. Perhaps the most common are 90 Ohms (USB) and 100 Ohms (Cat 5) however 77 Ohms, 120 Ohms and 125 Ohms are also often requested. Depending on the performance requirements of the cable, Habia Cable can make these components using either PE, PTFE or FEP dielectrics.
Power cores can be varied in size and colour coding. They can also be electrically isolated from the rest of the cable if required.
Probably the main component of any composite cable, signal wires can also be electrically isolated from the rest of the cable and are often specified as screened twisted pairs, triples and quads. Either colour coded or numbered (depending on size and cost) for ease of termination, Habia Cable can manufacture cables with hundreds of signal cores if required.
Can be applied as either a single, central strain cores or and overall braid (multiple strain wires throughout the cable are occasionally requested, but these are inadvisable as they often move within the cable when placed under strain, damaging the other components of cable as they do so). The level of load that can be supported varies from cable to cable, but Habia Cable have had experience with cables that can take loads of several tonnes.
Vent tubes are incorporated within cables for a variety of purposes as they are able to provide air in the cable for cooling, they can aid the buoyancy of a cable and they can carry high pressure air or oil for pneumatic and hydraulic use.
Once arranged in a suitable lay-up that can be produced by machine, the cable will be cabled together with back-twist and alternating layer directions to ensure the best possible construction. Over braids of copper and stainless steel wire or kevlar strands can be applied and (depending on the performance of the materials within the cable) one of a wide variety of inner and outer sheaths can be applied over the top of the whole construction. These sheaths can be marked with either Habia Cable's standard printing, designed to simply identify the cable for future reference, or with the customer's requested printing.
