HYAC solid copper conductor polyolefin moisture barrier polyethylene sheathed steel tape armored polyethylene sheathing City communications cables, copper and center structure through the insulated conductors twisted into a line, the line twisted into cable core. Aluminum-plastic composite tape Long tide with polyethylene tide barrier Sets, and steel stranded wire is integrated into a figure 8 PE sheathed cable, mainly for the transmission of audio, 150kHZ and below the analog signal and 2048kbit / s and below the digital signal. Under certain conditions, it can also be used to transmit digital signals over 2048kbit / s.

● wire: annealed bare copper wire, copper wire diameter0.40,0.50,0.60,0.70,0.80,0.90mm. 
● Insulation material: HDPE, the color of insulated wire conforms to the standard of international spectrum.
● Insulated wire pairs: pairs of single insulated wires are twisted in pairs at different pitches and the specified color combinations are used to identify pairs. Reduce crosstalk interference between pairs, low power consumption. 
● sheath: polyethylene PE sheath.
Self-supporting wire: suspension wire is of 7 strands galvanized steel strand, coated with thermoplastic to prevent corrosion of steel wire.

● DC Resistance: 20 ℃, 0.4 ≤ 148Ω / km 0.5 ≤ 95.0Ω / km 0.6 ≤ 65.8Ω / km 0.8 ≤ 36.6Ω / km. 
● Insulation electrical strength: conductor between 1min 1kv not breakdown. conductor and shield 1min 3kv not breakdown. 
● Insulation resistance: Each core wire and the remaining core connecting to ground, air filled cable is greater than 10000MΩ.km, filled type cable is more than 3000 m Ω. Km.
● Working capacitance: average 52 ± 2nF / km. 
● far-end crosstalk defense: 150kHZ specified combination of average power greater than 69dB / km.

Used in metropolitan area communication network construction, the city and suburban and regional communication overhead laying, no need of supporting wire, construction is convenient.
