The detailed specification of the RTU's and FRTU's look to be missing in both the documents. Please provide the same.

Corrugated Aluminium sheath shall be extruded.

As per IS:7098 (P-2),No corrugated aluminiumsheath details are mentioned. As per IS:7098(P-3)applicable for 66 kV grade and above cables ,corrugated aluminium sheath is recommended.As per amendment-1 of IS:7098(P-3) ,the aluminium sheath shall be smooth or corrugated.No process of aluminium sheath is specified in the IS specification.As per IEEE:635,specifications for aluminium sheath recommends for both type of sheath i.e seamwelded and seamless.So we request to amend the clause as seamless/seamwelded Corrugated Aluminium Sheath.

Corrugated Aluminium sheath need not be extruded.

Sr.No. 12 © Of Standard Technical

Particular for 1C33kV CU XLPE Cable Poly aluminium sheath is required for

the radial moisture barrier

Since as per Sr. No. 12 (a) ,Corrugated aluminium sheath is required to allow short circuit current.Corrugated aluminium sheath will carry the earth fault current and also will act as radial moisture barrier.So Poly Aluminium sheath is not required.Hence Sr. No. c. from the existing Sr. no. 12 may please be deleted.
