Mechanical performance.Existing rail traffic vehicles cable is generally hindered using thermosetting property low smoke and zero halogen of the tensile strength not less than 10MPa
The less toxic polyolefine material of combustion, the flame retardant property excellent to meet cable, the material is generally using magnalium flame-retardant system, but due to gold
Belong to a large amount of additions of minerals, improve the moisture pick-up properties of cable, during cable is electrified for a long time, after cable makes moist, there is table
The hidden danger of electricity is climbed in face.The cable is in laid processes simultaneously, and for generally use webmaster bed course as protection, webmaster bed course is polyester material
Material, generally using nitrogen phosphorus flame-retardant system, and nitrogen phosphorus fire retardant has the characteristics of meeting water migration, will after moving to webmaster mat surface
It reacts with the magnesium hydroxide in magnalium flame-retardant system cable, generates magnesium monohydrogen phosphate, cable surface is caused to generate spot, influence
The flame retardant property of cable longtime running.Therefore the characteristics of a kind of realization is small, light-weight is designed, avoids vehicle longtime running
In, the hidden danger of sheath cracking, the hidden danger that fire protecting performance reduces, additionally it is possible to the physical mechanical property of cable is improved, prevents from making moist, it is resistance to
The cable of high temperature is necessary, and is connected between each cable convenient and practical.
