Mine communication cable representation
Mine communication cable models, specifications, said. Such as:
a) have 30 pairs of stranded core for use in mines polyethylene insulated aluminum polyethylene bonded sheath steel wire armored, PVC sheathed mine communication cable is expressed as: MHYA32 30 × 2
b) has a core of stars stranded coal mine polyethylene insulated PVC sheathed mine communication cable, is expressed as: MHYV 1 × 4
Mining the main technical performance indicators of the communication cable
Conductor DC resistance Ω, 20 ° C / km 7/0.28 ≤ 45 7/0.28 (3 Steel 4 Cu) ≤ 73 1/0.8 ≤ 36.7
Intrinsic attenuation (800 1000HZ) dB / km ≤ 1.1 ≤ 1.3 ≤ 0.95
20 ° C core insulation of the cable insulation to resistance MΩ.km ≥ 3000
Line capacitor (800 ~ 1000HZ) uF / km ≤ 0.06
Near-end crosstalk attenuation (800 ~ 1000HZ) dB/500m ≥ 70
Inductance (800 1000HZ)-uH / km ≤ 800
AC power frequency resistance voltage 1.5KV/1min by
DC resistance difference of 2% of ≤ loop resistance
The use of features
The conductor of the long-term allowable working temperature -40 to +50 ° C;
The average maximum relative humidity ≤ 95% (+25 ° C)
Allow attached and installed the temperature should not exceed -10 ° C
