LOW HALOGEN AND HALOGEN-FREE LOW SMOKE RETARDANT POLYOLEFIN WIRES AND CABLES

DDZ-low halogen low smoke flame retardant WDZ-Halogen-free low smoke flame retardant

Low halogen and halogen-free low smoke flame retardant poly olefln wires and cables have the same electric properties as PVC insulated wires and cable. Its flame retardant properties complny to requitement of GB/T19666-2005(Identical to IEC 60332-3-25 bundle burning). Forlow halongen cable the quantity of the halongen acid is less than 100mg/g. For halogen-free low smoke flame retardant polyolefin wires and cables. The quantity of the halogen acid is less than 5mg/g, The smoke density complies to GB17651.2(Identical to IEC61034 burning chamber test method). Follow halogen cable the smoke densitny is larger than 30% For halogen-free low smoke cables the smoke density is larger than 60%. The cables have the same dimensions as PVC insulated cables. For low halonger cables the insulation should be halongen-free low smoke poly olelln or PE or XLPE. For low halogen cables the inner and outer sheath should be low smoke polyolefln sheath material. For halongen-free low somke cables the inner sheath should be low halongen low smoke or halongen-free low smoke polyolefln smoke polyolefln sheath materical .The outer sheath should behalohe-free low smoke polyoefln material. 

For anti-termite cables the sheath should be anti-termite halogen free low smoke sheath material
