　　Plastic fireproof cable (BBTRZ)
　　 This product is suitable for power transmission in power lines with a rated voltage of 0.6/1KV and below. Flame-retardant wires and cables are difficult to catch fire and have the ability to prevent or delay the spread of flames. They are used for laying in a variety of occasions where the cable has flame-retardant requirements, such as high-rise buildings, hotels, hospitals, subways, nuclear power plants, power plants, ore, and petroleum. , Chemical industry, etc.
Product implementation standard: GB/T127061-2002. GB/T183803-2008. GB/T17651 2-2002.GB/T1 76502-2002. GB/T1 921 6-2008
　　Instructions for plastic fireproof cable
　　Plastic fire-resistant cable is also called isolated fire-resistant cable. It is filled with a layer of odorless, non-toxic, halogen-free mineral compound material between the insulated core (outer diameter of the cable) and the outer sheath of the cable. When the cable is subjected to a fire, a large amount of crystal water is formed by filling and chromatography. When the flame temperature is lowered, the hydroxide is dehydrated into an infusible and non-combustible inorganic hard shell, which blocks the oxygen supply channel and achieves a high level of fire resistance. .　
　　Product structure
　　 plastic fireproof cable is composed of copper stranded wire, cross-linked polyethylene insulation, mineral compound filling and wrapping, and low-smoke halogen-free sheath.
　　 In addition to meeting the flame-retardant, low-smoke and halogen-free characteristics of low-smoke and halogen-free cables, 　　 plastic fire-resistant cables also meet the requirements of BS6387C, W, and Z laboratory standards.

　a, the name or trademark of the manufacturer i

　b, cable model and specification i

　c, length im

　d, manufacturing date year and month

　e, standard number i

　f, gross weight i kg.

　q, a symbol indicating the correct direction of rotation of the cable reel.

　3. Transportation and storage
