If we talk about the most unique cable then Polythene Jelly filled cable (PIJF) is an underground cable that has polythene as insulation on conductors and the inter-spaces between the conductors is fully filled with petroleum jelly. In the wire technology system petroleum jelly prevents ingress of moisture and water inside the core in the event of any damages to the cable. The cable is circular throughout its length and is free from any physical defects.

Polythene Sheathed Jelly Filled Cable with Ploy-Al moisture barrier is used for providing telephone connections to the subscribers.

It is said that the Jelly filled quad cable is used for special purposes like control circuits, Axle counters etc. in RE and Non-RE areas.
