Product Use:
Model name Use
The HYA copper conductors, solid polyolefin insulation and bonded aluminum sheathed local communication cable audio, 150Hz and below the analog signal and 2048 kbit / s and the following digital signal, and pipeline laying of overhead installation when hanging wire
HYAC copper conductors, solid polyolefin insulated aluminum bonded sheath self-supporting local telecommunication cables transmit audio, 150Hz and below the analog signal and 2048 kbit / s and the following digital signal, and applies to overhead installation, no hanging wire
HYAT copper conductors, solid polyolefin insulation and moisture barrier polyethylene filled sheathed local communication cables transmit audio, 150Hz and below the analog signal and 2048 kbit / s and below the digital signal is mainly used for pipe laying, and antiseptic effect.
HYA53 copper conductors, solid polyolefin insulated aluminum and plastic composite sheathed single longitudinally corrugated steel tape armored and PE sheathed local telecommunication cables transmit audio, 150Hz and below the analog signal can be buried laying field.
HYA23 communication cables for the transmission of audio, 150kHz and below the analog signal and 2048 kbit / s and the following digital signals can be transferred under certain conditions, the 2048 kbit / s or more digital signal.
HYAT23 communication cables for the transmission of audio, 150kHz and below the analog signal and 2048 kbit / s and the following digital signal, under certain conditions, but also can be transmitted to the 2048 kbit / s or more of the digital signal.
HYAT53 copper conductors, solid polyolefin insulation filled moisture barrier polyethylene jacket single longitudinally corrugated steel tape armored cable installed polyethylene sets of communication cable in the city 553 mechanical protective layer can be added to any structure of the cable in order to increase mechanical strength, improve the anti-erosion ability, is vulnerable to mechanical damage and erosion-prone areas of the telephone cable. Can be used either way, laying more suitable for rock buried laying.
HYA53, HYA553 model cable is limited to exceptional circumstances, must be used for pressure maintenance.
The HYA553 copper conductor Solid polyolefin insulation and block moisture barrier polyethylene sheathed single longitudinally corrugated steel tape armored polyethylene sleeve City communication cables
HYAT553 copper conductors, solid polyolefin insulation filled moisture barrier of polyethylene sheath double vertical package corrugated steel tape armored and PE sets of local telecommunication cables
Structural characteristics of local telecommunication cables: of HYA local telecommunication cable full chromatography insulation, aluminum integrated sheath (ie, longitudinally of the cable, shielded ribbon with jacket bonded into one to form a seal protection layer), with excellent electrical performance , construction and convenient features.
Local telecommunication cables electrical properties:
(1) DC resistance: 20 ° C, 0.5mm copper, less than or equal to 95Ω/km.
1min between the two. Insulation electrical strength: conductor 1kv not breakdown the conductor and shielding breakdown in the 1min 3kv not
Insulation resistance: each wire to ground and the rest of the wire core of HYA cable greater than 10000MΩ.km HYAT cable greater than 3000MΩ.km.
(4) Capacitance: average of 52 ± 2nF/km
5 the degree of far-end crosstalk defense: the average 150kHz specified combination of power greater than 69dB/km
