Supply a new one to rectify the latest information of a branch of the Tianjin Cable Plant HYA communication cable factory direct phone 0316-5962803

I plant the production of various models of communication cables (of HYA, HYAT, HYA53, HYAT53 HYA23, HYAT23 WDZ --of HYA and other series) products have passed ISO9002 and CCC certification, the Beijing Ter quality certification.
Of HYA: copper conductors, solid polyolefin insulation and moisture barrier polyethylene sheathed local communication cable
HYA53: steel plastic moisture barrier polyethylene sheathed copper conductors, solid polyolefin insulation block with armored polyethylene sheathed local communication cable
HYAT53: steel-plastic polyolefin insulated copper conductors, solid fill moisture barrier polyethylene sheath with armored polyethylene sheathed local communication cable
HYA22: copper conductor Solid polyolefin insulation and moisture barrier polyethylene sheathed, PVC Sheathed Local Telephone Cable
HYA23: copper conductors, solid polyolefin insulation and block moisture barrier polyethylene sheathed PE sheathed local telecommunication cables
Implementation of standards: YD/T322-1996

Structural features: HYA local telecommunication cables using all chromatographic insulation, aluminum integrated sheath (ie, longitudinally of the cable, shielded ribbon with jacket bonded into one layer form a seal retainer), with excellent electrical performance, construction and convenient features.

Electrical properties:

(1) DC resistance: 20 ° C, 0.5mm copper, less than or equal to 95Ω/km.

Insulated electrical strength: between conductors 1min 1kv without breakdown conductors 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

The FEXT defense degree: 150kHz when the average power of the specified combination is greater than 69dB/km.

HYA local telecommunication cables (widely used in the communication network construction of metropolitan area network overhead and pipeline installation, the main audio signal transmission)
