The CPEV-S series flame-retardant communication cables are multi-pair braided cables designed specifically for industrial control and signal transmission. The specifications of 3×2×0.5 and 10×2×0.5 offer the following features:


I. Structural Design
Conductor: Utilizes annealed bare copper wire with a diameter of 0.5mm, ensuring low resistance and high conductivity.
Insulation: High-density polyethylene (HDPE) or polypropylene material, full-spectrum marking for easy wire pair differentiation
Twisted Pair Technique: Pairs of twisted wires are twisted at different pitches to reduce crosstalk. "3×2×0.5" indicates 3 sets of twisted pairs, while "10×2×0.5" denotes 10 sets of twisted pairs.
Shielding and Sleeves
Aluminum foil/copper braid composite shield layer, excellent electromagnetic interference resistance
Flame-retardant PVC sheath, oxygen index ≥ 32%, meets the MT818.14 mining standard
II. Performance Parameters
Temperature Range: -40℃ to 50℃ (operational), -10℃ (installation)
Bend Radius: ≥ 12 times the cable outer diameter
Transmission Capability: Supports 2048kbit/s digital signal and 150kHz analog signal
Flame Retardancy Grade: Passed GB/T18380.3 vertical flame test
Typical Applications
Coal Mine System: Underground Communication, Gas Monitoring, and Personnel Tracking
Industrial Control: PLC Signal Transmission, DCS System Wiring
Traffic Facilities: Highway Emergency Phones, Railway Signal Transmission
Four: Selection Recommendations
3×2×0.5: Suitable for short-distance, low-logarithmic demand scenarios, such as internal connections of equipment
10×2×0.5: Ideal for trunk lines or multi-channel transmission, such as mine dispatching systems
Customized Services: Some manufacturers offer armored (such as HYAT53 type) or double sheath options.
