InnerCore is an independent Construction Company and Electrical Wholesaler, providing a wide range of internationally recognized products, which include: Lumber, Power & Instrumentation Cables, Overhead Line Equipment & Conductors, and General Electrical Contracting Equipment.

Composite or Multicore Cables

The core of our business model is provide the design that matches your high specification. Custom designed cables for demanding applications is one of our strengths. InnerCore’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. 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. Components can include (but are by no means limited to):

Lumber Products

We have long-standing roots in our community. With the same focus today as when we began, inner-core is dedicated to delivering high quality, sustainable products at competitive prices. This along with our valued relationships with our customers and vendors has allowed us to grow to where we are today.

Inner-core is a proud Canadian company. With some of our client relationships going back over 10 years, we know it's our dedication to exceptional service that keeps our customers coming back year after year. We're large enough to serve you efficiently, but small enough to serve you personally.

Data pairs

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

Power cores

Power cores can be varied in size and colour coding. They can also be electrically isolated from the rest of the cable if required.

Signal cores

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.

Strain wires

These 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 we have had experience with cables that can take loads of several tonnes.

Tubes

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.

Cabling or Twisting

Cabling (also known as twisting) is the process where cores are wrapped around one another, enabling the cable to be flexed. Without this rotation the core/s on the inside of the bend would be placed under compression and the core/s on the outside of the bend would be placed under tension, causing deformation of the cable, damage to the other cores in the centre of the cable and also breakages within the connectors.

Direction

Most cables will be manufactured with alternating left-hand (S) and right-hand (Z) layers. This is done to make the cable evenly balanced which can prevent it from twisting up in a single direction under dynamic use. Each core will also have back-twist applied to further prevent this twisting process and to ensure that the cable is as ‘dead’ as possible. It is most common to have the final layer as a left-hand layer, an example of which is a typical 19 core cable that would have:

• - Centre - 1x core laid straight.
• - First layer - 6x cores laid around the centre core with a right-hand lay.
• - Second layer - 12x cores laid around the first layer with a left-hand lay.
