Railway circuit signal cable service condition

1,cable using ambient temperature -20 ~ +70 ℃.
2,Cable conductor long time allowable working temperature should not exceed 70 ℃.
3,The ambient temperature should not be lower than -10 ℃.
4,shielded cable can be used to set the shield electrified track circuit section.
5,aluminum-sheathed cable with good shielding effect can be used for trunk segments of electrified track circuit or strong electrical interference region.
6,cable bending radius: non-armored cable should be not less than 10 times the cable diameter; armored cable should be not less than 15 times the cable diameter.

Railway circuit signal cable Technical performance

1)soft round copper wire nominal diameter of 1.4mm,complies with GB3953 .
2) the use of halogen-free polyethylene plastic insulated and made of red, green , white, blue four colors.
3) the above line group of four different colors insulated cores twisted star quads , four-wire stranding pitch different groups around the sparse ribbons of different colors to distinguish between non-hygroscopic .
4) cable core
a) In addition to the four core cable , the cable core stranding other specifications are the right direction to the adjacent layers twisted in the opposite .
b) A cable end line group compliance Q/321023KLA65-2001 sort of .
c) compliance with GB/13849.3 cable core wrapped with water blocking provisions of polyester fibers , then coated with flame-retardant glass ribbon.
d) within the cable core used in flame retardant glass filler wire rope .
5) the use of longitudinally shielded longitudinally with copper layer thickness of 0.1mm copper plastic composite with different performance requirements according to the cable , the aluminum layer with a thickness of 0.2mm aluminum composite or aluminum sheath.
PE inner sheath - low smoke , halogen-free , flame retardant PE material
Armor - used in line with the provisions of GB4175 galvanized steel with a nominal thickness of 0.3mm

PE outer sheath - low smoke , halogen-free , flame-retardant PE sheathing
