PVC Electric Cable Environmental Performance Testing
- Oct 10, 2017 -

The use of environmentally-friendly cables is strictly prohibited in developed countries, and our country attaches great importance to this area. China's relevant laws and regulations expressly require that important buildings prohibit the use of polyvinyl chloride wire and cable, the need to use halogen-free and low smoke cross-linked PVC Electric Cable, in order to avoid fire when a large number of smoke, chlorine, causing casualties.

Environmental protection cable refers to not contain lead, cadmium, hexavalent chromium, mercury and other heavy metals, do not contain brominated flame retardants, SGS recognized testing institutions for environmental performance testing, in line with the EU environmental Directives (RoSH) and higher than its index requirements. Do not produce harmful halogen gas, do not produce corrosive gases, burning a small amount of fever, do not pollute the soil of the wire and cable.

Environmental protection Cable will drive the development of cable industry, enhance the competitiveness of cable production enterprises, and in the green practice and innovation, so that the cable industry on the road to sustainable development more stable. In recent years, China's cable enterprises gradually to environmental protection cable, low smoke halogen-free cable and other efforts, as far as possible do not contain lead, cadmium, mercury and other heavy metals, do not contain brominated flame retardants, do not produce harmful halogen gases, do not produce corrosive gases, burning less heat, do not pollute the soil and so on, environmental protection cable will be more favored by the market, Higher orders are easier to obtain in the bidding of grid companies.

It is well known that lead and certain heavy metals can adversely affect human health, while in PVC formulations, it is often necessary to mix additives such as lead, cadmium, barium and other heavy metal compounds. However, since the 90 's, some developed countries and big electric companies have enacted regulations, in the use of PVC Electric Cable, there are eight kinds of heavy metal content should not be greater than the provisions. These new rules both bring new business opportunities to wire and cable manufacturers and pose serious challenges to PVC cable manufacturers.

Good flame retardant performance is a very obvious advantage of PVC Electric Cable, however, the ordinary flame-retardant PVC cable in the fire burning, will release a thick black smoke and a large number of HCI gas, resulting in the fire after the "Two disasters", seriously affecting the evacuation of personnel and the development of Fire rescue work. Therefore, at the same time, in the case of flame-retardant wire and cable, the requirements of "low smoke" and "low HCI" will be further put forward in some use occasions.

For some of the electrical appliances that may be in contact with food, blood products, medical and health appliances and children's electric toys, they require no lead, no heavy metals, and no poison (or low toxicity). This means that all ingredients used in PVC formulations should be non-toxic. The cable material contains a large number of plasticizers, but the manufacture of non-toxic materials must choose Non-toxic plasticizer. Therefore,PVC Electric Cable this PVC material requirements than lead-free heavy metal material higher, the price is naturally more expensive.

As environmental issues become more and more important, many countries have already formulated various environmental protection policies,PVC Electric Cable so people prefer to use green environmental protection cable. Low Smoke halogen-free flame retardant cable material is one of the most popular environmental protection cables.
