In this case It is 400kV HVAC interconnector

This is related with the Subsea 400kV Power Cable crossing number of subsea FO cables at almost 90 degree . The concern is EMF from subsea AC power cable could impact the FO cable's performance as it could affect the copper conductor of the FO cable that powers the repeaters. If the repeater(s)...

I believe the rating will also depend upon if it is a 3 core cable or single core cable . I too get 10% difference in rating with single core cable but with 3 core cable the difference is very less

Do you expect providing the shunt reactor at receiving end will compensate the charging current and overall current in cable will be less?

Since it’s a subsea installation , installation cost will be very high with multiple cable circuits.Also there is limitation on available cable corridor width . So use of 3C 400sq mm cable seem to be most cost effective solution

HVAC is found to be most cost effective and feasible solution

Thanks for your response . If I have understood rightly , providing the shunt reactor at sending end will not have any impact on total current flow in the cable ;rather it would be only useful if shunt reactor will be connected at receiving end which may reduce the current in cable as well as...

we are working on cable ampacity calculations for 400kv 40km length HVAC subsea cable connecting offshore PV generation plant to the grid . Due to space restriction it will be possible to provide shunt reactor at the sending end only (generation end) . In this regard I would like to know if...

we have been calculating ampacity of subsea 400kV 3 core 2500 sq.mm and 2000 sq.mm Cu cables using CYMCAP software . But we noticed that there is only marginal increase (Les than 10A) in the current carrying capacity of 2500 sq.mm cable over 2000sq.mm. Where as there has been significant...

for the purpose of 400kv subsea cable sizing connecting generation plant to grid, I was trying to understand to what extent Providing the Shunt reactor only at the sending end of the subsea cable circuit may help in reducing the overall current flow in the cable and if we still need to consider...

How effective is drying the power cable with nitrogen purging? Can it confirm life of the cable Same as new cable after this process of drying ? How many years it may take to form form electrical tree and breakdown the insulation if moisture is retained within the insulation?

In one of my 10km long , 400kV Lead sheathed XLPE insulated Power Cable installation project, contractor had completed few cable joints up to copper casing but he could not provide final water proofing compound and coffin box since supply of the same was awaited. During this stage there was...
