Railway tracks can experience frost heave during severe winter weather, posing a threat to the safety of railway travel. Especially in cold zone railways located at high latitudes, the huge changes in temperature have a huge impact on their roadbed and steel rails. Due to the huge temperature difference between winter and summer, these areas are most prone to roadbed frost heave. To solve this problem, MI armored heating cables can be used, which have excellent insulation and heat tracing effects.
What are the advantages of installing MI armored heating cables on railway tracks to prevent freezing? The MI heating cable is an all metal integrated structure with seamless technology and one-time molding. The internal magnesium chloride becomes a good insulation material, which is explosion-proof, fireproof, waterproof, and does not produce toxic gases. This can also effectively avoid the invasion of snow water and cold air on the MI heating cable, and has effective anti-corrosion ability, ensuring that this electric tracing cable has a service life of up to 10 years under normal circumstances.
The MI armored heating cable used in railway tracks has good mechanical performance due to its sturdy structure, which can withstand twisting, squeezing, bending, pulling, friction, and general heavy handling. The magnesium oxide of the insulation layer of the MI armored heating cable is an inorganic substance, and the core and outer sheath are made of metal, so the aging problem is fundamentally solved and the service life of the tracing band is greatly extended. Due to the reliable metal sealing tube and good grounding of the electric heating strip, it is particularly suitable for various explosion-proof locations; Low temperature resistance, non brittle during construction at low temperatures, easy to construct and maintain in winter.
The installation of railway tracks using MI armored heating cables can directly solve the problem of track frost heave in the simplest way, and is currently one of the most widely used track maintenance methods in the world. MI armored heating cables have become heating and antifreeze products due to their numerous advantages and significant effects.
