Trunking and Cable Management

Cable Management in Kenya

Cable management refers to the management of electrical or optical cable in a cabinet or an installation. These Cables can easily become tangled, making them difficult to work with, sometimes resulting in devices accidentally becoming unplugged as one attempts to move a cable. “Cable spaghetti”, and any kind of problem diagnosis and future updates to such enclosures could be very difficult.

Hubtech limited Cable management both supports and contains cables during installation, and makes subsequent maintenance or changes to the cable system easier. Products such as cable trays, cable ladders, and cable baskets support a cable through cabling routes.

 

Cable selection

The choice of cables is also important. For instance, ribbon cables used to connect Parallel ATA drives to the motherboard can disrupt the airflow inside of computers. This makes case fans less effective.

Most SATA cables are more compact and therefore do not have this problem.

The Cable labeling

Color-coding of cables is sometimes used to keep track of which is which. For instance, the wires coming out of ATX power supplies are color-coded by voltage. Documenting and labeling cable runs, tying related cables together by cable ties, cable lacing, and rubber bands keep cable organized.

Also running them through cable guides, and clipping or stapling them to walls are other common methods of keeping them organized. Above drop ceilings, hooks or trays organize cables and protect them from electrical interference.

Planning is especially crucial for cables such as Thicknet that do not bend around corners easily. Also fiber optic which is very difficult to splice once cut.

Cable strain relief

Cable strain relief is mechanical protection for flexible electrical cables, wires, conduits, and pneumatic hoses.

With a strain relief component, the connection between a flexible electrical line and its connection port protects against mechanical stress. Usually, the lines clamp into single cable clamps made of plastic or metal. Another possibility is to use so-called cord grips which consist of weaved wire strands that put a grip around the cables.

A more cable-friendly alternative is attaching the lines to special strain relief plates using common cable ties. In the case of industrial applications, these strain relief plates are also cost-effective and are normally designed for holding one single line.

Furthermore, most of the available cable clamps are not very flexible when it comes to routing lines with varying diameters. That causes higher acquisition and storage costs. The installation of the single cable clamps can take a lot of mounting time, depending on the laying length of the lines. Strain relief plates are therefore a more flexible solution that allows a parallel routing of several lines with varying diameters.

The strain relief is often required for terminated electrical lines to plug into sockets or ports to prevent unplugging or accidentally ripping out of the connector. This is the point at which the lines have to be strain relieved depending on the application.

Components are also used in applications where cables, conduits, and hoses expose to constant dynamic stress (cable carriers/drag chains).

Hubtech limited Computer Cable Management, structured cabling, LAN cabling

Generally, one end of a cable terminates in the data cabinet. The other end of a cable ends at the desk. The cable management needs at either end are different.

Buildings and office furniture are often designed with cable management in mind. For instance, desks sometimes have holes to pass cables, and dropped ceilings, raised floors, and in-floor cellular raceway systems provide easy access. Some cables have requirements for minimum bending radius or proximity to other cables, particularly power cables, to avoid crosstalk or interference. Power cables are separately grouped and suitably apart from data cables and only cross at right angles which minimizes electromagnetic interference.

The organized routing of cables inside the computer case allows for optimal airflow and cooling. Good cable management also makes working inside a computer much easier by providing safer hardware installation, repair, or removal. Some PC mod enthusiasts showcase the internal components of their systems with a window mod. This displays the aesthetics of internal cabling as well as the skills and wealth of the Modder.

Software, such as data center infrastructure management (DCIM), is sometimes used to manage cabling for large infrastructures.

Cable planning

Large companies often encompass vast networks of cables. All of these need servicing, removed, added, and so on throughout an installation lifecycle — cable planning is a necessity.

Hubtech limited employs Different methods of cable planning, depending upon the level of detail required for proper management using Spreadsheet software. There is often however, a need to visually organize information. For proper visualization of cabling, companies may opt to use a cable management software package.

Hospital Use

In hospital situations, cable management can be critical to preventing medical mistakes.

Cabling in healthcare facilities grounds, shields, and routed by life safety codes to minimize interference with medical equipment.

Office Use

Hubtech limited manages cables by five methods in commercial buildings:

Concrete trenching – a trench is dug into the building’s concrete. Install Cabling and floor and the concrete seals the trench.

Floor decking – Install cables on the ceiling of the floor below. Drill Holes through the floor and install outlets on top of the floor.

Overhead cabling – Install cables on the ceiling. Cable drop downs give users access to outlets.

Access flooring – Install cables below a raised floor.

In Floor Cellular Raceway Systems – utilize enclosed steel raceways located within a concrete floor slab to distribute power, data, and telecom cabling throughout a space to any.

Cord concealers (also called cord protectors) are commonly used in offices to prevent accidents while protecting the cord and the appliance it’s attached to. Office furniture can sometimes have built-in cable management solutions.

When moving equipment

Cable management is particularly important in powered equipment which must move large distances while tethered to a power source and control cabling. There are several common methods of cable management.

With a suspended sliding coil, the cables coils like a spring, with each loop of the coil attached to a sliding shoe on a track. As the cabling paid out, the shoes slide individually along the track and the coils expand. When sliding in the other direction, the coils fold back together into a compact spiral. This is also referred to as a festoon.

Folded linear cable uses either a flexible backbone shell or a flat cable folded into an arc along its long axis. This style of cabling is very common in computer printers to connect the printhead to the circuitry. It is also used in very large linear moving gantries. The cables flex only in a small region in a tight radius and so need to be very flexible.

Types of Hubtech limited Cable Management Trunking

Metal Trunking

Metal cable conduit trunking and rigid metal conduit are among the most heavy-duty and robust options you can buy. It comes in a range of options for carrying various cables in conduit arrangements. It includes a wide variety of diameters and cross-sectional areas for different types of cables and sizes of cable (diameters).

Galvanized steel conduit is often preferred for outdoor and underground cable runs. It is also preferred in any other places where there’s likely to be a degree of exposure to moisture. Stainless steel trunking is sometimes preferred for aesthetics where a cabling run will be in full view. An aluminum conduit is a great choice for many lightweight applications, such as when wiring needs to run across ceilings.

As with plastic trunking and conduit, metal versions can be either round, square, or slim/flat in profile. It may be fully enclosed or slotted to allow for better thermals through rapid heat dissipation. This also enables easier access and visual identification of wires.

Plastic Trunking

Plastic cable trunking is a popular choice for a relatively simple and cheap conduit option that’s robust enough to withstand everyday hazards (dirt and moisture). Bought in both rigid and flexible lengths, depending on whether you need to focus on physical protection or routing convenience.

Common types of plastic conduit include PVC and UPVC trunking, halogen-free ABS conduit, polyamide, and polypropylene. A flat PVC cable conduit is often used around skirting or in dado installations. White or black plastic trunking is a common sight in various workplaces, particularly offices.

Plastic trunking sizes vary widely – widths can range from 3mm to over 300mm, while depths go from under 10mm to over 100mm. Standard lengths fit the space you’re working in, particularly if you’re choosing PVC trunking or similar. The best combination of lengths and thicknesses will depend on the routing and cable management you need. It also depends on the amount and type of wiring (single-core cables, multi-core cables, earth cable, etc) you’re putting through.

PVC Plastic Trunking

PVC electric cable trunking is the most popular and affordable material. PVC cable trunking is specifically designed for use in industrial environments and where cable ventilation is a requirement. It also ensures tidy wiring systems and protects the cables from damage. Our PVC cable trunking range consists of mini cable trunking and maxi cable trunking which is very easy to install and refurbish. You can also have the option of self-adhesive electrical trunking wiring systems to secure surfaces without the need to nail, protecting your property from damage.

EMC Trunking

For some types of installation, ensuring you have fully electromagnetic compatibility (EMC) between your conduit cable and trunking enclosures will be vital. Dedicated EMC cable, glands, and EMC shielding provide a screening effect for conductors. This provides better earthing, helps to minimize interference, and lowers the risk of shorting or electromagnetic radiation.

Always be sure to search for products listed specifically as ‘electrical cable conduit’ or ‘electrical trunking systems. If you’re installing this type, particularly for cabling runs with a high current carrying capacity.

PVC FLEX and Conduits

Flexible PVC conduits can act as electrical cable insulation and a rubber alternative. It has various uses in construction and plumbing thus providing a lightweight, cost-effective, and durable material to use.

  • Liquid Tight Conduit Resists Corrosion, Oil and Water, Smooth Inside for Easier Wire Pulling.
  • Resists Crushing and Stretching, Outdoor Sunlight Resistant.
  • Integral Rigid and Flexible PVC Construction, UL Rating 140 degrees F.
  • Conduit is Flexible – Can be specifically used in extremely Tight Quarters, Light Weight – Lower Installed Costs.

How to Install Cable Management Trunking

In all cases of electrical installation, if you’re unsure about any aspect of working with live trunking cable, you should always seek guidance from us. Installing the cable trunking itself isn’t strictly an electrical task, however, and it’s relatively easy to DIY in most cases.

Unfortunately, there’s no single rule for how to install it correctly. Knowing how to install cable trunking and mini trunking is about understanding the product you’re buying, and what you need it to do.

Some types of conduits and cable protection are precisely designed to be quick and easy to install, including self-adhesive trunking. Other types may snap-fit together around the cable you’re routing or require the cable to run through beforehand. Heavier cables and more robust installations, such as full galvanized steel trunking with rigid corner joints, will be a more complicated and demanding process.

Also

Depending on the trunking type, cable conduit size, cross-sectional area, amounts of cable, and install location, you need several additional tools to complete installation. These can range from screwdrivers and drills to saws, putties and sealants, stud finders (wall scanners), and various others besides.

Bear in mind that installing outdoor cable trunking for waterproof cabling runs will require a different set of checks requirements. This is more than most basic indoor applications and unburied cables, such as fixing trunking to an office wall for network cables (Ethernet cables). You may also need to know how to cut cable trunking neatly for the materials you’re using. There is also need to know how to plaster over wires, or how to make trunking bends at a more precise angle. These sorts of instructions include the manufacturer specifications for specific products and conduit brands.
