Self Regulating Switchpoint Rail Heaters
Introduction
Many railway switchpoint suffer during the winter months, from snow and ice blocking the moving rails and point mechanisms, causing failures and disruption to traffic.
A number of systems have been used in the past in an attempt to keep the points clear but they are generally inefficient in their use of power, and expensive to maintain.
The increasing use of the self-regulating, energy efficient GrayBar system overcomes these deficiencies and, using the latest technology from Raychem for the heater elements, results in a highly reliable and efficient system.
Design
The GrayBar system is supplied as a kit, containing all the components to install a complete switchpoint heating system. The strip heater is positioned in the web of the stock and moving rails and applies heat effectively to the areas most prone to the effects of snow and ice. The points mechanism can also be protected and the flexibility of the heater allows it to be fed through chairblock slots and other obstructions on the rail. The special GrayBar fixing clip design results in a smooth profile and long service life.
Installation
The GrayBar system can be installed with the minimum of effort and avoids the need for expensive and time consuming track possessions. No heavy equipment is required and the work can be carried out by a small team of personnel. All the components required to complete each switchpoint heating system are included in a compact handy box. To connect the "cold leads" to the power supply cables, suitable joints are available together with 4-way rubber moulded blocks if required.
