Product Description / PRODUCT

Layer stranded nylon sheathed microcable (24-288 core)

Product Description / PRODUCT

1. Colored fiber 2. Fibre paste 3. Groove 4. Cushion 5. Tear rope 6. Water blocking layer 7. FRP8. Filled rope 9. PA12 outer sheath

Product Description / PRODUCT

The Mini central tubular air-blown cable is used to place the colored 2-24-core fiber in the bundle tube, and the outer skin is extruded into a high-density polyethylene outer sheath.

Product Features / PRODUCT
