MI Heater Cable Mineral Insulated Heating Cable Strip for Railway Snow Melting

MI Heater Cable Mineral Insulated Heating Cable Strip for Railway Snow Melting

Product Introductions:

For a long time, the railway system in the work of cleaning snow entirely rely on manual to complete. With the substantial speed railway operations, the new way to enhance and improve the level of automation of railway passenger safety requirements of punctuality, the railway system currently used can not meet the requirements.

So, the Railway Snow Melting MI Heater Cable is designed.

Railway turnouts snowmelt system is one of the auxiliary equipment railway turnout switching equipment, the use of the basic rail of the turnout at the waist, rail slope and tow point at fixed clamp flat ribbon straight, U-shaped and L-shaped electric heating strip tight solid mounted, and supporting control device, through the acquisition of rail temperature, air temperature and snowfall information, automatic control turnout heating circuit work, and remote monitoring, dynamic monitoring of the ambient temperature, the rail temperature, snowfall state, the heating time, heating circuit status parameters.

Product Features:

    (1) electric heating strip is a nickel-chromium stainless steel shell heat transfer body, built to optimize nickel-chromium resistance wire as the heat source, is filled with a dense mineral magnesium oxide thermal insulation layer between the electric wire and housing;
    (2) The mineral insulated heating cable proprietary sealing technology; ensure the electrical performance of snowmelt heating strip does not exceed 20% decline in a decade; suitable for railway track turnout and basic heating requirements, the pressure can be up to 2500V, without breakdown phenomenon;
    (3) Article snowmelt heating resistant to vibration, impact resistance, corrosion-resistant features. End of the wire cable in order to increase the wear resistance of polyurethane sheath strong resistance, tear and chemical resistance, as well as oil, grease, gasoline, water, ozone, UV radiation, hydrolysis and microbes.
    (4) The system is in the process of installing and using the full implementation of the provisions of the railway system of national standards, the turnout at the installation of high efficiency electric part shall not destroy the original turnout of any parts, components, ensure rail mechanical strength unaffected. Quick and easy installation, does not substantially affect the rail operation.
    (5) The system has a reliable safety and security system equipment, and railway signaling systems and other electrical systems without any interference, without affecting its normal work

Main Technical Parameters:

(1) Power supply voltage: 380V / 220V 50Hz or customized according to user requirements
(2) at ambient temperature T = -40 ℃, wind speed = 10m / s, the system can maintain the temperature of the heating surface switch> 2 ℃.
(3) at ambient temperature T = -30 ℃, the snow melting capacity of 10mm / 12h, that is able to maintain with the melting snow with the drop, leaving snow and ice;

(4) separated electrically heated snow bar at the rated voltage, when the ambient temperature is 35 ℃, maximum surface temperature <400 ℃, in the course of actual snowmelt surface temperature <180 ℃.
(5) Insulation resistance ≥500MΩ.
(6) The compressive strength> 2500V. Protection: IP65
