DNO cable

Hi just a quick question I used to know this but now can't remember if the old PILC cable joined to a PVC covered cable as a replacement for a faulted section  how do they keep the earth impedance down? Especially if the PILC length is now a lot less than it was supply's in properties along the road are a mix of TNS and CNE  Thanks
