The laying of the cable carrying the record underground voltage of 55,000 ¥., in Holland in cennexion With the pumping for the reclamation of the Zuyder Zee, presents many difficulties. The cable was laid in 1992 and hes been in satisfactory operation since. Each drum weighs 64 tons.
The handling of a cable of some *4-in, in diameter and drawing 6} tons along the ground, passing all obstacles including small creeks, requires great care to prevent internal damage to the insulation. The methods adopted for negotiating these difficulties will be of particular interest as they reproduce conditions which obtain in many parts of China.
In order that the cable may be carried across the canal, two lighters ayo placed across the waterway and the cable laid on bridge picces between the two lighters. When the cable is in position, the bridge pieces are removed and the cable allowed to sink into the bed of the canal.
The panoramic view of the operations displayed gave a good illustration of how the work was carried out and the labour distributed over the work. The lay-"ing of this cable was of sufficient interest to warrant a visit of inspection of a deputation of prominent British engineers, amongst them being Sir Tom Callender and his son. Sir Tom Callender is one of the greatest engineers of this age and chairman of the firm which hears the name of his grandfather and which is one of the leading cable manufacturing firms in Great Britain.
