Rail transit cables

All cables used for power traction and signal transmission in subway and station construction can be supplied. The cables have the properties of low smoke, halogen-free, flame retardant, waterproof, rat and ant resistant, and UV resistant. It is especially suitable for the wet and watery laying environment of the subway, with long cable life cycle, high electrical strength and system reliability.

Rail transit cable is a new special wire and cable product born with the development of urban transportation. It can be widely used in power transmission and distribution networks of intercity rail transit, including various types of intercity railway (track) lines and intercity trains in operation, namely high-speed railway.

Rail transit cable is a new type of special wire and cable product with the development of urban transportation. There are DC and AC cables for rail transit. Rail transit cables for DC traction are generally single core 1500V, 750V and 300V, with armored and unarmoured types; The voltage grade of AC type rail transit cable is 3.6/6kV-26/35kV, generally single core and three core.

Through reasonable structural design and selection of raw materials, rail transit cables have many functions such as low smoke, halogen-free, flame retardant, waterproof, insect bite resistant, UV resistant, etc., meeting special requirements for cable cleaning, environmental protection, flame retardant, etc. in crowded places and important facilities. Compared with similar technologies at home and abroad, it has the following characteristics: copper core conductor, low resistivity, good conductivity, and excellent mechanical and physical properties; Cross linked polyethylene insulation, with excellent electrical properties and mechanical and physical properties; The comprehensive waterproof layer structure is adopted, namely, winding waterproof tape, longitudinally wrapped aluminum plastic composite tape and extruded polyethylene inner protective layer, which has excellent waterproof performance; It is wrapped with high flame retardant tape, copper tape or steel tape for armouring, with good flame retardant and rat resistant functions; The weather resistant low smoke halogen-free flame retardant polyolefin material is used as the outer sheath of the cable, which has the properties of anti ultraviolet, flame retardant, non-toxic and low smoke.
