Ø 中心加强件:玻璃纤维杆--FRP,可能会根据结构设计外护一层PE。

Ø 松套管:以PBT为原材料,松套管内含12芯(或以下)光纤、内部填充阻水纤膏。

Ø 填充绳:PP材质,用于填充缆芯结构(有需要时)。

Ø 绞合方式:松套管和填充绳以SZ形式绞合于中心加强件上。

Ø 阻水方式:阻水带纵包于缆芯,半干式阻水(油膏填充式阻水可选)。

Ø 撕裂绳:2根聚酯撕裂绳在每层护套内。

Ø 外护套:黑色LSZH。

 

Ø Central Strength Member (CSM): Glass fiber reinforced plastic rod (GFRP), with PE sheath covering when needed.

Ø Loose Tube: PBT plastic material, containing 12 fibers and filled with a suitable water tightness jelly.

Ø Filler Elements: PP plastic rods, when needed.

Ø Stranding: Loose tube & filler SZ stranded around CSM.

Ø Longitudinal Water Tightness: Dry core with water swellable elements (Wet core is optional).

Ø Ripcord: 2 polyester ripcords under each sheath.

Ø Outer Sheath: Black LSZH.

重要 Important

由于LSZH光缆的特殊性质,不同芯数、结构阻燃等级会导致产品规格不同如下48芯设计仅针对普通LSZH光缆

如有其它结构要求,请与我们联系会协助提供符合您要求的设计。

Due to the particularity of LSZH cable, different core、structure and flame retardant rating will lead to different designs. The following 48-core design is only for ordinary LSZH cable.

If you have any other requirements, please contact us and we will provide the design that meets your requirements.
