HYA Applications

HYA Application

Solid-core insulated non-filled cables are suitable for urban and rural telecommunication lines in local telecommunications networks, as well as for dedicated network lines connecting to the public network. They require suspension line support during overhead installation. Under environmental conditions of -30℃ to +60℃, the cables maintain their mechanical and electrical properties unchanged.

Primary Electrical Performance

DC Resistance: At 20℃, 0.4 ≤ 148Ω/km, 0.5 ≤ 95.0Ω/km, 0.6 ≤ 65.8Ω/km, 0.8 ≤ 36.6 Ω/km. Insulation Electrical Strength: Not punctured by 1kV within 1min between conductors, and not punctured by 3kV within 1min between conductors and shielding.

Insulation Resistance: Each core wire is grounded to the rest, with充气电缆exceeding 10,000 MΩ.km and filled cables exceeding 3,000 MΩ.km.

Working Capacitance: Average 52±2nF/km

Remote Crosstalk Defense Level: At 150 kHz, it refers to the average power of the combination being greater than 69 dB/km.
