Remember to keep electric appliances and cables out of reach for small children. It’s also a good idea to plug any wall sockets you’re not using at the moment. These safety plugs are easy to install and remove with the enclosed tool and you can use them both in earthed and unearthed sockets. See the ...
EHV/HV Cable Sheath Earthing Introduction - ResearchGate
WebEarthed and unearthed systems. All the voltages given above are for cables operating on an “earthed” system Uo/U. However there are some systems that are “unearthed” that is to say U/U the voltage between the conductor and “earth” is the same as the voltage between phase conductors for example – 10/10 kV. WebSo if we used earthed cable in unearthed System, It may be chances of insulation puncture. So unearthed cable are used. Such type of cable is used in 6.6 KV systems where resistance type earthing is used. Nomenclature In simple logic the 11 KV earthed cable is suitable for use in 6.6 KV unearthed system. in-car out-car
