HYAC Self-supporting Communication Cable

HYAC Self-supporting Communication Cable
Item : HYAC
Brand : ATTRAISE
HYAC is 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 diameter 0.40, 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.
Insulation 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.
Self-supporting wire: Suspension wire is of 7 strands galvanized steel strand, coated with thermoplastic to prevent corrosion of steel wire.
Sheath material: Polyethylene PE sheath
Operating Temperature: -30℃～+60℃.
