| XQT-2 high-powered flame-retardant fire&oxygen separated fiber glass wrap tape | |
| application | | | |
| technical parameter is as follows: | | | |
| no. | item | | typical value | |
| 1 | unit weight | g/m2 | 180-200 | |
| 2 | thickness | mm | 0.17±0.02 | |
| 3 | width | mm | according to the requirements | |
| 4 | longitudinal strength | N/25mm | ≥440 | |
| 5 | oxygen index | % | ≥50 | |
| | | | | |
| function of the fire separated layer in the flame-retardant cable: | |
| 1,when used as the insulated core,it can keep stabilization of the core structure. | |
| 2,it can ensure the tightening of the core and prevent from damaging of the insulation. | |
| 3,it can prevent bonding of the insulation,outer sheath and the inner coating layer,and will not affect mechanical,physcial and the electrical performance of the cable. |
| 4,when cable is burning,it can absorb a great deal of heat.the formed carbonization layer can separate the oxygen gas and protect the insulation in order to enlarge loss of the fire. |

| | | | | |
| requirements of fire separated wrap to the flame-retardant cable: | |
| 1,It could not absorb the moisture. | | | |
| 2,It can ensure the tightening of the core and prevent from damaging of the insulation. | |
| 3,It shall of good flexibility and easy to be wrapped. | |
| 4,It shall have same operation temperature with the cable. | |
| 5,It could not damage the environment and the human body in the wrapping process. | |
| 6,It should have good tensile strength and certain elongation rate. | |
| 7,It should have good carbonization performance while burning. | |
| | | | | |
| storage: | | | | |
| it shall be stored in the dry and clean warehouse and the shelf life is 6 months after the manufacturing date. |
