Detailed promotional film showing the processes involved in making Electric Power Cables.
Reel 3. Mobile oil treating equipment is shown. Man opens the door of a large van. Inside the van is testing and treating equipment. Oil pressure in the cable is checked. C/U of gauge being used to test the pressure. Various shots of men working to check the cables. Several men stand in a narrow trench hauling the cable along. The cable is fed along the trench by hand. The cable is pulled around a bend. Looks like very hard, labour intensive work. Interesting overhead shot of two men pulling the cable through the trench. Looks a bit rude!
Cable passes under the railway. M/S of a train passing over a bridge - camera tilts down to show the men tugging on the cable. At the end of the pull, men stand on the grass pulling the cable - almost like a tug of war team. Various shots of the cable being pulled into place. C/U of man tying a piece of string around the cable. Jointing an oil-filled cable in the trench, stripping, serving and baring the joint are all demonstrated. Testing the oil pressure before cutting is also demonstrated. C/U of gauge being used to test pressure. C/U of man sawing through a piece of pipe with a small hacksaw. The ends are inserted in ferrule. Two workers join two pieces of cable with a small attachment. The ferrule is clamped with a hydraulic press. The cable is insulated with paper. The metal sleeve is fixed and wiped joints are made. C/U of heat being applied to the cable.
