Application
It is suitable for the wrap tape and fire separated flame-retardant layer of the flame-retardant and fire-resistant cable .Serial high-powered flame-retardant ,oxygen and fire separated wrap is suggested used as the cabling wrap tape for the XLPE cable ,and use the inorganic paper rope as the filler ,thus it is possible to achieve flame-retardant for the cable and improve its flame-retardant grade.

Function of the fire separated layer in the flame-retardant cable
When used as the insulated core ,it can keep stabilization of the core structure.
It can ensure the tightening of the core and prevent from damaging of the insulation.
It can prevent bonding of the insulation ,outer sheath and the inner coating layer ,and will not affect mechanical ,physical and the electrical performance of the cable .
When cable is burning ,it can absorb a great deal of heat .The formed carbonization layer can separated to the oxygen gas and protect the insulation in order not to enlarge loss of the fire.
Requirements of fire separated wrap to the flame-retardant cable
It could not absorb the moisture.
It should have high oxygen index.
It should have good flexibility and easy to be wrapped .
It should have same operation temperature with the cable .
It could not damage the environment and the human body in the wrapping process.
It should have good tensile strength and certain elongation rate.
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.
