Installing Electric Cables in Market Square Stafford

Description:This photograph showing a large trench the high street was taken during the period that the additional cables were being added to cope with the decision to double voltage. If you look carefully at the photograph taken in the main street you can see at the bottom of the trench in the foreground the five cables running along the trench, but at the far end of the trench you can see that the two outermost cables leave the trench one on each side of the trench. The inner three cables (original cables) are still in the trench disappearing into the soil at the end of the trench. The reason for the trench being opened is to add two extra cables to the original three cables changing the original Hopkinson three wire installation into a Hopkinson five wire system the two newly installed outer cables would carry the 210V positive and 210V negative cables.
