gui chao cable news: environmental protection cable performance and technical requirements
from:guichao author:admin click: 519 addtime:2017-04-24 17:08:46
environmental protection cable has several characteristics:
1 does not contain halogen, no lead, cadmium and other heavy metals, do not pollute the environment.
2 safety, flame retardant, combustion of harmful gases, smoke less.
3 the use of renewable, abandoned when the environment does not harm,
dioxin and other carcinogenic substances will not spread.
4 do not change the physical properties and use characteristics of the product.
western developed countries in research and development, the establishment of environmental regulations in the forefront,
in the last century, japan did not replace the rapid rise of green materials pvc,
pay more attention to the development and production of environmental protection cables and standards,
7 environmental communication cable standards have been developed,
1 environmental protection alarm cable standards, 1 environmental power cable standards.
according to the domestic and international attention and attention to environmental protection,
according to the actual situation of the cable industry,
reference to foreign standards in this regard,
such as the united states us epa, the eu en,
ling'an wire and cable industry association, 2005
wire and cable branch
cooperative development of zhejiang province db33/t609-2006
"cable tv system 75 physical foaming polyethylene insulated and ecological coaxial cable" local standard,
judging from the current situation, this is the first official release of the implementation of eco cable standards.
the standard for catv ecological environmental performance, mechanical and environmental performance,
combustion performance, test methods and so on.
the main ecological environment, combustion performance, test methods are as follows:
1 eco environmental performance (mg / kg)
lead (pb) <300
caries (cd) <100
mercury (hg) <100
chromium (cr6 ) <100
polybrominated diphenyl ethers (pbb) and polybrominated diphenyl ethers (pbde) <1000
2 combustion performance
flame retardancy (single vertical combustion) <60s
transmittance 60%. min
sheath material hcl5mg/g & max
the ph value of the combustion gas 4.3min
the electrical conductivity of jacket material is 10 s/mm max
