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.
HYAC copper core solid polyolefin insulated aluminum-plastic bond sheath non-filled city communications cables in accordance with the national standard and the Ministry of Posts and Telecommunications standard production.
HYAC type local telephone cable can be used in the towns, suburbs and factories and mines in the communication lines. Mainly used for pipe laying, overhead installation need to use hanging wire support. Buried in the outdoor use of oil-filled to be waterproof and moisture-resistant, direct use of buried steel belt armor.
