Type: cable for fire signaling, with aluminum foil shielding, with flame propagation delay and without halogen release.
International symbol: JB (St) H Bd (VDE 0815).
Rated voltage: 450 / 750V.
Field of use: indoors, for connecting devices used in fire signaling. In places with fire risk, the insulation having a resistance to flame propagation of at least 180 minutes and the operation of the system for 30 minutes.
construction:
Conductor: solid copper, protection on mineral bundles.
Insulation: on each bundle, without release of halogen (HI2); halogen-free foil; aluminum foil cased with special materials; spare wires.
Sheath: red with flame retardant and no halogen release (HM2; no release of toxic or corrosive gases), the bundles are twisted into four threads and they are twisted together.
Ambient temperature: posed: -30 ° C to + 70 ° C, moving: -5 ° C to +50 ° C.
Electrical properties at 20 ° C: conductor resistance: max. 73.2 Ohm / km, insulation resistance: min. 100 MOhm x km, maximum construction capacity: max. 120 nF / km, flattening the conductor at 800 Hz: kb. 1.2 dB / km, coupling capacity: max. 200 pF / 100 m.
