Installation of heating-elements
To allow fixing of the heating elements with the special fixing elements at the rail, you need free space of 65mm below the bottom of the rail. If you have a ballast bed remove some ballast under the rail and place it back after mounting the heating elements. The connecting head fasteners have to be fixed very carefully with a torque of 65 Nm!
It is not allowed to use own additional mounting material like toothed locked washers or something else!
Stock rail heating ( rail heating )
At this form of point heating the tubular heating-elements, with 180° bent off connecting head, are fitted with special clamps at the stock rail, two clamps in each space between the sleepers – and with one connecting head fastener for each heating-element.
At the tip of the switch ( point ) the heating element should be between 200 – 600 mm longer at the stock rail than the switch blade.
