HYAT53 is a copper core solid polyolefin insulation filled tide polyethylene sheath steel tape armored polyethylene sheathing City communications cables, the structure of the double sheath structure, the first layer of aluminum-plastic composite tape Zhanmo block Tide polyethylene sheath, the second layer is coated with steel armor plus polyethylene sheath cable, filled with petroleum paste. Mainly used to transmit 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 full-color chromatography. 
● 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. 
● mechanical protective layer: 0.15mm double-sided coated embossed steel strip, wrapped or wrapped around the basic cable on the cable surface is specially treated to prevent corrosion and water intrusion. 
● Shield: 0.2mm thick double-sided aluminum coated with corrugated (or not corrugated) longitudinal package in the core package tape, lap joints. 
● sheath: polyethylene PE sheath.

● 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 1min 1kv breakdown between conductor and shield 1min 3kv not breakdown. 
● Insulation resistance: each core and the remaining core ground, filled cable is greater than 3000MΩ.km. 
●. Working capacitance: the average 52 ± 2nF / km. 
● far-end crosstalk defense: 150kHZ specified combination of average power greater than 69dB / km.

This product is mainly used for local telecom network urban and rural telecom lines, but also for access to private networks dedicated network lines; 53 armored mechanical protective layer can increase the mechanical strength of the cable to improve anti-erosion ability is susceptible Mechanical damage and vulnerable areas designed telephone cable; can be used pipelines, overhead laying. More suitable for direct burial.
