摘要

A single column pantograph isolator has arms which fasten at their ends onto cables or rods for electric connection to high voltage. The arms are copper tubes, flattened at their ends (10) and contact clamps (13) are used as the above means by which they are fastened to the flattened ends by a screw. The clamping element (15) is used for connection to cables or rods (18). This clamping element is a split block with a hole through it for the rod. Screws are fitted for clamping it onto the rod.
