First, the implementation of standards: reference to 1.TICW06-2009 computer and instrumentation cables, 2.GB/T19666-2005 flame-retardant and fire-resistant wires and cables general standard production.
Usage: Intrinsically safe cable has low capacitance and low inductance and has good shielding performance and anti-interference performance, so the explosion-proof performance is better than general computer cable and control cable. It is suitable for use in the circuits of centralized distribution system and automated detection and control system with explosion-proof requirements as propagation line.
Third, the use of characteristics and technical parameters:
1. Rated voltage Uo / U: 300/500V
2. Maximum working temperature: 70℃, 90℃, 105℃, 120℃, 180℃, 200℃, 260℃ (according to customer requirements)
3.Minimum ambient temperature: -42.5℃, -40℃, -25℃, -20℃, -15℃ (according to customer requirements)
4. Fire resistance: NH, steel belt armored: 22, steel wire armored: 32
5. Flame retardant grade: ZA (Class A flame retardant), ZB (Class B flame retardant), ZC (Class C flame retardant), ZR (flame retardant).
6. Shielding options: P copper wire, P1 tinned, P2 copper tape, P3 aluminum foil
7. Minimum bending radius: the cable without armored layer should be not less than 6 times the outer diameter of the cable.
8.Cable with armored layer should be not less than 12 times of the outer diameter of the cable.
9. PE insulation, PVC insulation, F insulation, G insulation (according to customer's requirements).
