HVDC CablesRenewable energy is generated from renewable energy sources. These renewable energy resources consist of producing energy from solar, wind, geothermal, hydropower, biomass and biofuel. The transmission of voltage and current over a direct current (DC) transmission line is different contrary to the alternating current (AC) transmission line. DC electricity does not consist of an alternating flow of electrons from an area of negative charge to an area of positive charge.

In order to deliver the renewable energy, the generation will be done using AC generators. The energy will then be transmitted using collector cables. These collecting cables transfer the electrical energy to a common voltage from where the AC power is converted to DC using a process called rectification. After that, the power is transmitted through several miles’ distance high-voltage direct current (HVDC cables) and then converted back to AC by a HVDC Cables 02process known as inversion. The HVDC Cables provides the interconnection between the grid and the local user.

Some of these HVDC Cables application are as follows:

     1) Solar Energy Distribution

In solar energy distribution systems, HVDC cables play a very vital role. HVDC cables have the ability to transmit that DC signal having fewer power losses relative to HVAC Cables. The transmission from the solar panels to the solar system is done using appropriate solar cables. 

     2) Wind Energy DistributionHVDC Cables 03

In wind energy distribution systems, the HVDC cables should be more oil-resistant because of the exposure of hydraulic oil. Hard insulation makes the wire harder and more prone to expose the conductors with sufficient wear. Special consideration of insulation on these wires is taken while installation of this type of renewable energy source. 

     3) Energy distribution to submarine

Mass-impregnated high-voltage direct current (HVDC) cables have the ability to deliver high power over long distances. Especially when it comes to developing a link between submarines, the longest submarine cable link established between a distance of 580 km. It was between Norway to Netherlands.
