HYA outdoor communication cable of large number 5020.4

Outdoor HYA communication cable | large of number 50 * 2 * 0.4 copper communication cable HYA Description: HYA communication cable, also known as large of number, solid insulation filled cables for urban and township telecommunications line local telecommunications networks, but also for private network line access to the public network. In the cable core and the inner and outer surfaces of the shield with petroleum jelly filling and pouring process, to prevent moisture intrusion. Under ambient conditions for a 30 ~ C a 60 ~ C, mechanical and electrical properties of the cable remain unchanged. Mainly used for transmission of audio, 150KHz and below the analog signal and 2048 Kbit / s and below the digital signal, under certain conditions, it can also be used to transfer 2048 Kbit / s or more digital signals. Mainly used for pipe laying.
