Mardia Cables adheres to the strictest manufacturing standards, utilizing premium-quality materials to guarantee exceptional strength and efficiency in our cables.
At Mardia Cables, our conductors are carefully manufactured using high conductivity copper and H2/H4 grade aluminum. We provide a variety of options, including solid, stranded, circular, and shaped conductors, available in different sizes. Be assured that all our conductors strictly conform to both national and international standards, including IS 8130, IEC 60228, and BS 6360.

At Mardia Cables, we utilize a standardized color scheme to designate colors to the different cores present within the cable, specifically focusing on control cables. The identification of colors plays a crucial role in facilitating easy recognition and simplifying the wiring process. Our color scheme is outlined as follows:
Single Core: Red, Yellow, Blue, Black, Grey, White, etc.
2-Core: Red and Black.
3-Core: Red, Yellow, and Blue.
4-Core: Red, Yellow, Blue, and Black.
5-Core: Red, Yellow, Blue, Black, and Grey.
In instances where cables have more than five cores, adjacent cores (counting the core and directional) in each layer are rendered in blue and yellow, while the remaining cores in the layer adopt a light grey hue. Furthermore, core identificati on within control cables can be provided using numbers to enhance convenience.
The laying-up process is employed to form the core bundle after insulating the conductors.
During production, all cores within the cables undergo comprehensive testing and are laid up following the specified color code. Our utilization of advanced lay-up machines guarantees a consistently uniform circularity of the cable.
Every one of our multicore cables is equipped with a shared covering called the inner sheath. This protective layer is applied using an extrusion process over the laid-up cores. The primary purpose of the sheath is to guarantee the circularity of the cores.Mechanical protection is provided by applying armouring on the outer layer of the inner sheath of the cables. For single core cables utilized in AC systems, non-magnetic material is used for armoring to reduce losses resulting from magnetic hysteresis.
In cases where the diameter of the inner sheath is up to 13 mm, G.I. wires are employed for armouring, while for diameters exceeding 13 mm, G.I. strips are used. These armoring materials adhere to the standards set by IS 3975.
A durable outer sheath made of high-grade PVC is applied over the armoring of armoured cables and the inner sheath of unarmored cables. Typically, a black outer sheath is utilized as it provides optimal resistance to outdoor exposure, although any color can be accommodated if specified.The cable's name and size are inscribed on the outer sheath. Furthermore, the voltage grade, manufacturing year, and the word 'ELECTRIC' are printed on the outer sheath at regular intervals.
