Varmekabelteknik - Electrical Heating Systems and Equipment

Switchpoint Heating AB supply electrical heating systems and accessories for railways, industry applications and building sites. We deliver complete custom made heating systems for railway, industry and buildings including installation details and control systems.

Railway switch-point heating

Railway switch-point heating is installed in order to maintain the function of the point mechanism without the need for manual clearing. The installation involves positioning flexible heating elements that can be made up to 25 meters along the foot of the stock and switch rails.

In extreme cases, double elements will be installed in the section of the point blade with the most movement, in order to quickly melt any snow or ice falling off passing trains as a result of vibration.

The point rod pit may also be provided with heating by means of our point rod heaters, which are connected up to extension terminals on the heaters positioned on the stock-rail. The heating elements are covered with stainless-steel protective channels fixed to the rail using spring steel clips.

The channels are supplied in lengths of 1m and are available in rigid and flexible designs. Clips are available in several different types fitting most rail profiles found in the switch-points that exist today.

The VELOX switch-point heating system can be used with most existing control systems providing 230VAC to the point heating system. The heating elements are of a self-limiting type, which means they are energy efficient as they decrease the heat output when the temperature rises.

The elements are double-insulated and lack protective earthing in order to avoid causing signalling faults if damaged. Heaters are powered by a waterproof IP68, quick-connect system simplifying maintenance.

VELOX rail-point regulator

We manufacture custom-designed automatic-control cabinets containing thyristor control devices and soft-start regulators, as well as equipment for remote control and logging of energy consumption and temperature, amongst other data.

The parameters of the Velox rail-point regulator can be checked and adjusted from a remote computer connectedto the internet, and logged temperature and current values may, in the same way, be read or downloaded for further analyses. Communication are possible by a fixed telephone connection or a 3G modem.
