? 中心加強件：玻璃纖維桿--FRP，可能會根據(jù)結(jié)構(gòu)設(shè)計外護(hù)一層PE。
? 松套管：以PBT為原材料，松套管內(nèi)含12芯（或以下）光纖、內(nèi)部填充阻水纖膏。
? 填充繩：PP材質(zhì)，用于填充纜芯結(jié)構(gòu)（有需要時）。
? 絞合方式：松套管和填充繩以SZ形式絞合于中心加強件上。
? 阻水方式：阻水帶縱包于纜芯，半干式阻水（油膏填充式阻水可選）。
? 撕裂繩：2根聚酯撕裂繩在每層護(hù)套內(nèi)。
? 外護(hù)套：黑色HDPE。
? 吊線部分：鍍鋅鋼絞線。
? Central Strength Member (CSM): Glass fiber reinforced plastic rod (GFRP), with PE sheath covering when needed.
? Loose Tube: PBT plastic material, containing 12 fibers and filled with a suitable water tightness jelly.
? Filler Elements: PP plastic rods, when needed.
? Stranding: Loose tube & filler SZ stranded around CSM.
? Longitudinal Water Tightness: Dry core with water swellable elements (Wet core is optional).
? Ripcord: 2 polyester ripcords under each sheath.
? Outer Sheath: Black HDPE.
? Messenger Wire: Stranded Galvanized Steel Wire.
重要 Important
由于8字纜的特殊性質(zhì)，不同芯數(shù)、結(jié)構(gòu)會導(dǎo)致產(chǎn)品規(guī)格不同。如下48芯設(shè)計僅針對單層護(hù)套、無鎧裝8字型架空光纜。
如有其它結(jié)構(gòu)要求，請與我們聯(lián)系，會協(xié)助提供符合您要求的設(shè)計。
Due to the particularity of aerial Fig-8 cable, different core and structure will lead to different designs. The following 48-core design is only for single PE sheath, no armor aerial Fig-8 cable.
If you have any other requirements, please contact us and we will provide the design that meets your requirements.
