Coal dedicated communication cable prices HYA 1.1 Basics of copper conductors, solid polyolefin insulation moisture barrier polyethylene sheathed local telecommunication cables, mainly used for 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 transfer 2048kbit / s or more digital signals. Suitable for city, suburban and local area overhead or pipe laying lines, it can also be buried. 1.2 Description 1, product performance standards: reference MoC YD / T630-93 standard and march up to corporate standards 2, single annealed bare copper wire, diameter: 0.4mm 0.5mm 3, insulation material: high density polyethylene or polypropylene, marked in accordance with international chromatography insulated wire color 4, insulated in pairs: the single insulated wire twisted pairs according to different pitch and with specified color combinations to identify the first pair; reduces crosstalk interference between pairs , power consumption small 5, the sheath material: HYA Copper polyolefin insulated aluminum sheath for outdoor use local communication 1.3 HYA solid insulated non-filled application cables for telecommunications lines in the city and towns of local telecommunications networks, but also for private network line access to the public network. When an aerial installation needs support with hanging wire. At -30 ℃ ~ + 60 ℃ ambient conditions, mechanical and electrical properties of the cable remain unchanged. 1.4 The main electrical properties 1. DC Resistance: 20 ℃, 0.4 ≤148Ω / km 0.5 ≤95.0Ω / km 0.6 ≤65.8Ω / km 0.8 ≤36.6 Ω / km2 Insulation Electric Strength: 1min 1kv no breakdown between conductors and conductors Shielded not breakdown 1min 3kv 3. Insulation resistance: each core line with the rest of the core ground, inflatable cable than 10000MΩ.km, filled cable than 3000MΩ.km. 4. Capacitance: mean 52 ± 2nF / km 5. FEXT defense degree: the average value of 150kHZ combination of power greater than 69dB / km.
