Application of LSZH GB31247 Flame Retardant Optical Cable

The new generation of CPRsupportTM LSZH series is highly flame retardant LSZH products developed by ATP for fiber optic cables, cables, and network cables, meeting the latest EU CPR building codes and GB31247 requirements. Compared to traditional LSZH products, CPRsupportTM has undergone more long-term research and development, more complete and rigorous comprehensive performance testing. It is a new upgraded version of the traditional lszh jacket material, fully improved in the selection of raw materials, flame retardant system innovation, lubrication system innovation, and production process control.

1. High flame-retardant performance:

Fully support the optical cable through the EN 50575:2014+A1:2016 B2ca, Cca, Dca level test (different product models meet different CPR level requirements);

Very effective total heat release and heat release rate peak control scheme. The carbonization efficiency is higher. When burning, the table surface can be quickly charred to form an effective fiber protective layer; the generation of smoke during combustion and the release of halogen acid gas are also in full compliance with the CPR regulations;

2. Safety and reliability:

Fully support the cable through environmental resistance test as follows;

Passed high temperature cracking test (YD/T1113 100°C, 96H, no crackle on the surface);

Pass the high-temperature aging test (100°C, 168H, tensile strength and elongation change rate ≤ 30%);

Pass the -25°C low-temperature shock test.

3. Good wear resistance:

Better wear and scratch resistance under same test conditions of polymer compound manufacturer;

4. easier processing:

Fully meet the high-speed extrusion of optical cables; the wire diameter is round and stable, less flow (less die deposit), good color stability, higher processing yield rate.

5. Stable performance and quality:

The product batch stability and uniformity are guaranteed.
