From the begining of 20th Century Paper insulted Oil impregnated lead sheathed Power Cables were the unanimous choice of Power Engineers for underground transmission and distribution due to their excellent electrical and thermal properties.The cables which were laid in 1950 in our country are still in operation.
These cables were heavy due to lead sheath for vertical runs as in that case the oil got accumulated in the lower portion of the cables.Any punture in the lead sheath lead to cable failure as the electrical properties of Manila paper weakens in the presence of moisture . The jointing of the cables also required a special skill.Cables up to 132 kv were made with paper insulation and they are still the service.
Polymer technology made a rapid stride during and after second world war and we witnessed a Plastic revoltuion.Various plastic like PVC,POLYETHYELENE,NYLON,POLYESTER etc. were invented and put to commercial use during this period.
