This product is copper core polyethylene insulated communications cables in the city, produced according to YD / T322-2013 standards, mainly used for signal transmission between equipment, as well as rail transit, cableway and other projects, with complete specifications, the structure of diversified features. This series of products include filled and metal armor structure, with anti-aging, waterproof, anti-external stress and other characteristics, with a small attenuation, stable impedance, high shielding effect of electrical properties. It retains its excellent electrical and mechanical properties in a complex environment with more reliable performance than conventional cables.
HYA-type local telephone cable can be used for urban, suburban and factories and mines in the communication lines. Mainly used for pipe laying, overhead installation need to use hanging wire support HYAC. Buried in the outdoor use of the need to oil-filled waterproof moisture HYAT, buried directly use the need steel belt armor HYAT22. Structure – Henan Xin Bo Special Cable Co., Ltd.
