• Conductor: Solid annealed bare copper conductor, copper diameter 0.40, 0.50, 0.60, 0.70, 0.80, 0.90mm
• Insulation material: High Density polyethylene, color coded in accordance with international standard telephone industry code
• Insulation wire pair: the single insulated wire twisted pair according to the different pitch and with specified color combinations to identify the line. To reduce the mutual interference of crosstalk between line pair, small power loss
• Mechanical protection layer:0.15mmcorrugated steel tape is longitudinally applied to the inner sheath. The special handling steel tape prevents the entrance and migration of water and provides corrosion protection.
• Shielding: 2.0mm thickness of corrugated (or non-corrugated) aluminum polyethylene laminate tape is longitudinally applied around the cable core.
• Sheath material: Polyethylene PE sheath

Electrical Performance

• DC Resistance:20℃, 0.4 ≤148Ω/km 0.5 ≤95.0Ω/km 0.6 ≤65.8Ω/km 0.8 ≤36.6 Ω/km
• DielectricStrengthDC: Between conductor and conductor1min 1kv; Between Shield and conductor 1min 3kv
• Insulation Resistance: Pair to Ground, gas-filled communication cable is above 10000MΩ.km
• Mutual capacitance average: average value 52±2nF/km
• The signal to far-end crosstalk radio (150kHZ): the specified average power is above 69dB/km
• Operating Temperature: -30℃～+60℃

• Apply to the local telecommunication network of city and township, access public network. Type 53 armored layer can increase the mechanical strength of the cable and improve the anti-erosion ability. It is designed for the area which is susceptible to mechanical damage and erosion. The cable can be used for aerial, duct installation, but more suitable for direct buried.
