Oil Filled Cable and Paper Insulated Lead Cable

As many HT cable on site are been installed since back in the 60s or 70s, a lot of TNB cable found underground are usually this two types, that is

1. Oil Filled Cable
2. Paper Insulated Lead Sheathed Cable - PILC

These two cables been heavily in used for utilities back in the 1970s as before armored cable or even XLPE cable being use.

And when diversion needed for this cable, usually many steps and precautions actually needed for that.

I have include some information on transition joint for the diversion works which is written by cable jointer manufacturer. Raychem.
