How to Select Power Cables to Meet Your Needs?

    All applications that require power or lighting have electrical and mains power cables. Additional information is required when choosing a cable system to ensure seamless operations. The service conditions, construction, kind of load served, mode of operation, maintenance, and other aspects of the cable system are included in this knowledge.

    How do I choose a power cable?

    Here are the essential things to consider when choosing the best fire cable for your application, no matter what industry you're in.

    Installation of Fire Rated Flexible Cable

    Depending on the load served and the distribution system, power cables in Singapore can be utilised for interior or outdoor installations. To guarantee that the cable systems run correctly, a thorough awareness of local conditions, installation professionals, and maintenance crews is required. When pulling tensions are applied incorrectly, cable insulation is frequently degraded or destroyed during installation. You can reduce network downtime and the likelihood of connectivity issues if you have a professional installation and maintenance crew.

    Construction of fire rated cable

    The type of cable structure required for a particular installation has an impact on the power cable you choose. Meanwhile, conductors, cable arrangement, insulation, and finish covering are all part of cable construction.

    Conductors — Conductive materials like aluminium and copper are utilised because of their workmanship, the environment they will be exposed to, and their ease of maintenance.


    Cable configuration — Conductors can be organised in single-conductor or three-conductor cable configurations. Single conductors are easier to install and splice than several conductors. They can also be used to connect several cable circuits together. Three-conductor cables, on the other hand, have ground wires that give the lowest impedance path.

    Insulation and a final coat of paint— This is usually determined by the type of installation, service conditions, ambient operating temperature, and load type served. Unusual conditions, such as a corrosive atmosphere, the presence of oil and solvents, insect and rodent risks, severe temperatures, and the presence of ozone, may exist in some installations.

    Operation of the Fire Rated Flexible Cable

    The insulation on the cable must be able to withstand the voltage strains encountered under diverse operation situations. The suitable phase-to-phase voltage is used to determine cable insulation, and the general system category is determined.

    How you decide what size of electrical wire do you need?

    Current carrying capacity, short circuit rating, and voltage control are all considerations to consider when choosing a cable size.

    The cable's current carrying capability is determined by the cable's thermal heating.

    Short circuit rating – the cable's capacity to withstand short circuits and heat damage is tested.

    Voltage regulation is examined to ensure that the load voltage is correct.

    Shielding of Fire Rated Cable

    Shielded power cables provide more protection than unshielded power wires. The electric field is partly in the insulating system and partly in the air in power systems with no metallic or shield covering.

    Surface discharges will occur if the electric field is powerful, as in the case of medium and high voltage, causing air particle ionisation. Shielding in power lines reduces the risk of major safety issues while also increasing the circuit's reliability.
