Environmentally friendly cable is mainly characterized by several aspects:
1. Does not contain halogen, lead, cadmium and other heavy metals, does not pollute the environment.
2. Safety, flame retardant, combustion of harmful gases produced by less, less smoke.
3. Renewable utilization, no harm to the environment when discarded, there will be no dioxin and other carcinogenic substances spread.
4. Does not change the physical properties of the product and the use of characteristics. Western developed countries in the R & D production, the establishment of environmental regulations in the forefront, in the last century did not Japan to replace the rapid rise of PVC with green materials, pay more attention to the development and production of environmentally friendly cables and standard-setting, have formulated seven environmentally friendly communication cable standards, an environmentally friendly alarm cable standards, an environmentally friendly power cable standards. According to the domestic and foreign attention to environmental protection and the degree of concern for the city's cable industry, the actual situation, with reference to foreign standard information in this regard, such as the United States US EPA, the European Union EN, etc., in 2005, Lin'an City, Wire and Cable Industry Association, together with the National Electrical Apparatus Industry Association, Wire and Cable Branch of the development of the Zhejiang Province, DB33/T609-2006, "cable television system 75Ω physical foam Polyethylene insulated eco-friendly coaxial cable" local standards, from the current situation, this is the first officially released the implementation of eco-friendly cable standards. The standard outlines and specifies the CATV eco-friendly performance, mechanical and environmental performance, combustion performance, test methods and other aspects. Its main eco-friendly, combustion performance, test methods are described below:
1. Eco-friendly performance (mg/kg)
① lead (Pb) <300
② caries (Cd) <100
③ Mercury (Hg) <100
③Mercury (Hg)<100 ④Chromium (Cr6+)<100
⑤Polybrominated biphenyls (PBB)+Polybrominated diphenyl ethers (PBDE)<1000
2. Combustion performance
①Flame retardant (single vertical combustion)<60S
② light transmission rate of 60% - min
③ Sheath material HCL5mg/g-max
④Sheath material combustion gas pH value 4.3min
⑤ Sheath material combustion gas conductivity of 10μs/mm-max
