Connecting people and places, transferring huge amounts of data at extremely high speeds makes the world go around. Telecommunications cables provide the vital infrastructure to support these networks, from island interconnects to regional festoons, river and harbor crossings to inland routes. Working closely with our customers we have a flexible approach to system design and an exceptional track record of delivery.

Submarine cable systems are laid underwater for communication and electric transmission. These cables carry signals over long distances and are primarily used to connect the mainland with large islands. The growing need to interconnect grids for optimum utilization of renewable energy, for example, offshore wind energy is among the major factors boosting the demand for submarine power cables. Further, the increasing requirement to generate electricity from offshore oil and gas facilities is another factor that propels the growth of the submarine power cable market. Submarine cables or submarine fiber-optic cables are laid on the ocean beds with the goal to connect various regions and continents across the world for the communication purpose.

Applications in communication and power sectors to drive growth of submarine cable system market

Communication Cables

Telecom carriers, mobile operators, multinational corporations, governments, content providers, and research institutions, among others, across the world rely on submarine communication cables to send and receive data. According to Tele Geography, as of 2018, there are over 1.2 million km of submarine communication cables in service all over the world. There are 2 categories of measuring a cable’s capacity—potential capacity and lit capacity. Potential capacity is the maximum capacity of a submarine cable if the cable owner installed all available equipment at the ends of the cable. Lit capacity tracks the capacity available for use on a submarine cable, i.e., the actual traffic-carrying capability of the system.

Power Cables

Submarine power cables are widely used to link shore-based power grids across bays, rivers, straits, etc. Nowadays, submarine cables carry power between countries and for offshore installations, e.g., oil/gas platforms and ocean science observatories. These cables also transfer power from offshore renewable energy schemes to shores, e.g., wind, wave, and tidal systems. A few more applications of these cables include power transfer from energy sources, including offshore renewable energy schemes, to consumers, interconnecting different regional electrical transmission networks to facilitate global energy trading and supply to remote areas. There are 2 types of submarine cables: high-voltage alternating current (HVAC), which is limited by transmission distance, normally less than 80 km; and high-voltage direct current (HVDC), used for longer distances and for system interconnection. For transmission, AC is converted to DC through cables, and back to AC at the other end. Diameters of these cables can go up to 300 mm, depending on the current-carrying capacity and degree of armour protection. Submarine oil/gas pipes can go up to a diameter of 1,500 mm, while submarine telecommunications cables can go up to a diameter of 17–50 mm, depending on armour.

Our cables are made to resist external aggression and provide the highest protection against water ingress, ensuring the maximum design life for your subsea system.

WATER TREATMENT CABLES

Our comprehensive range of water treatment cables provides to the various applications specific to industrial-scale water treatment plants and reservoirs both for drinking and for the safe processing and return of contaminated water to the environment. This includes power supply cables for pumps, drainage and treatment systems.

Our water treatment cables are built to withstand extreme weather conditions, mechanical stress and the chemicals used in water purification. Importantly, we offer submersible cables suitable for contact with potable water, the water treatment cable is submersible to a depth of 800 meters.

In addition to specialist water treatment cables, we supply a wide range of power, data, control and instrumentation cables for applications found in buildings adjacent to the water treatment operations. Our water treatment cables are used globally in desalinization plants. Our water treatment cable solutions cover the full spectrum, from expert technical support with cable selection, design and testing, to logistical support ensuring the timely delivery of our cables according to the strictest schedule.
