Description :
Quotation for Railway Signal Cable PZYA-28 * 1.0
This product is suitable for transmitting railway signals, audio signals or automatic signal devices with rated voltage of AC 500V or DC 1000V and below
Control circuits, among which railway signal cables with comprehensive sheath and aluminum sheath have certain shielding performance, suitable for electrified sections or other strong
Laying in areas with electrical interference.
1. Usage characteristics
The operating temperature range for the cable is -40 ℃ to+60 ℃.
1.2 The long-term operating temperature of cable conductors should not exceed+70 ℃.
1.3 Environmental temperature for cable laying: PVC outer sheath cables should not be lower than 0 ℃; Polyethylene sheathed cables should not be lower than -20 ℃.
1.4 Allowable bending radius of cables: Non armored cables should not be less than 10 times the outer diameter of the cable; Armored cables should not be less than 15 times the outer diameter of the cable.
The ideal shielding coefficient of 1.5 comprehensive sheathed railway signal cables is ≤ 0.8; The ideal shielding coefficient of aluminum sheathed railway signal cables is ≤ 0.3
