松套层绞式单细圆钢丝铠装光缆（gyta53+33）
strandedloose tube single-steel-wire armoredcable
产品描述 description
gyta53+33光缆的结构是将250µm光纤套入高模量材料制成的松套管中，松套管内填充防水化合物。缆芯的中心是一根金属加强芯，松套管（和填充绳）围绕中心加强芯绞合成紧凑和圆形的缆芯，缆芯内的缝隙充以阻水填充物。涂塑铝带（apl）纵包后挤一层聚乙烯内护套，双面涂塑钢带（psp）纵包后挤制聚乙烯外护套。再经单细圆钢丝铠装后，最终挤制聚乙烯外护层成缆。
the fibers, 250µm, are positioned in aloose tube made of a high modulus plastic. the tubes are filled with awater-resistant filling compound. a steel wire locates in the center of core as ametallic strength member. tubes (and fillers) are stranded around thestrength member into a compact and circular cable core. an aluminum polyethylenelaminate (apl) is applied around the cable core, which is filled with the fillingcompound to protect it from water ingress.then the cable core is covered with athin pe inner sheath. and a psp is longitudinally applied over the innersheath, the cable is covered with a peouter sheath. after the single-steelarmored, the cable is finally completed with an outersheath.
