As environmental issues are becoming more and more important, many countries have formulated a variety of environmental policies, so people are more inclined to use green cable. Low smoke halogen free flame retardant cable material is one of the more popular environmental protection cable. Although China’s market demand for green cable is growing, but compared with developed countries, China has a long way to go in the development of relevant policies and mandatory application, we expect that China should improve the environmental cable standards as soon as possible.
High-quality environmentally friendly cable has the following eight characteristics:
- Requirements for low content of lead and heavy metals
As we all know, lead and certain heavy metals can adversely affect human health, and in PVC formulations, usually need to be mixed with additives such as lead, cadmium, barium and other heavy metal compounds. However, since the 1990s, some developed countries and big
Electrical companies have formulated regulations, in the PVC wire and cable used, there are eight heavy metal content shall not be greater than the provisions. These new regulations both to the wire and cable manufacturers to bring new business opportunities, but also to the PVC cable manufacturers to bring serious challenges.
Heavy Metal Content Limits: Environmentally friendly wire and cable must be strictly controlled for heavy metals. Specifically, the content of heavy metals such as lead, cadmium, mercury and hexavalent chromium must be below the specified limits. For example, the content of lead is usually required to be less than 300mg/kg, cadmium less than 100mg/kg, mercury less than 100mg/kg, chromium (hexavalent) less than 100mg/kg. these limits are to ensure that wire and cable in the process of use and abandonment will not cause pollution to the environment.
- Requirements for low smoke and low hydrogen oxide
Good flame retardant properties is a very obvious advantage of PVC wires and cables, however, ordinary flame retardant PVC cables in the fire will release thick black smoke and a large number of HCI gases, resulting in a fire after the “second disaster”, seriously affecting the evacuation of people and fire rescue work.
The evacuation of people and fire rescue work. Therefore, in the wire and cable flame retardant requirements at the same time, in some cases will be further proposed “low smoke” and “low HCI” requirements.
Halogen content limit: environmentally friendly wire and cable should not contain halogen or halogen content is very low. Halogen in the combustion process will produce harmful gases, causing harm to humans and the environment. Therefore, environmentally friendly cables are usually required to contain no halogens, or halogen content is very low to ensure that no toxic gases will be released in the event of fire and other situations.
- Requirements for low or no toxicity
For certain household appliances that may come into contact with food and blood products, medical and health appliances, as well as children’s electric toys on the cable, in addition to the requirement of lead-free and heavy metal-free, but also non-toxic (or low-toxicity). This means that the PVC formulations used in
All component materials used in a PVC formulation should be non-toxic. Cable materials contain a large number of plasticizers, but the manufacture of non-toxic materials must be non-toxic plasticizers. Therefore, the requirements for this kind of PVC material are higher than those for lead-free and heavy metal-free materials, and the selling price is naturally more expensive.
- Excellent flame retardant properties
Environmentally friendly wire and cable should have good flame retardant properties. This is usually verified by the cable’s flame retardant test, such as single vertical combustion test. The flame retardant properties of the cable meet the requirements of GB/T 18380-2008 to ensure that the spread of fire can be slowed down in a fire.
- Smoke density and light transmission rate
During combustion, environmentally friendly wire and cable should produce less smoke and maintain good light transmission. This helps to maintain a clear line of sight in the fire, facilitating evacuation and rescue work. Specifically, the smoke density of the cable when burning should meet the standard requirements of GB/T 17651-1998, and the light transmission rate should be not less than 60%.
- Environmental certification
Environmentally friendly wire and cable should pass the relevant environmental certification, such as the EU RoHS Directive. These certifications ensure that the environmental performance of the cable meets international or regional environmental standards.
- High efficiency, long life, easy to recycle
High efficiency: qualified environmental protection wire and cable should not only meet the standards in environmental protection, but also to ensure good electrical properties, such as electrical conductivity, insulation, etc., to ensure that the cable in the use of the process of stability and reliability.
Long life: environmentally friendly cables should have a long service life, which reduces the frequency of replacement cables, but also reduces the consumption of resources and energy, thereby reducing the burden on the environment.
Easy to recycle: environmentally friendly wire and cable should also be considered in the design of its recyclability, in order to facilitate the recycling process after the cable is discarded, to achieve the reuse of resources.
8.Other prohibited items
Currently, the European Union is hearing the regulations, the following items are restricted to ensure that wire and cable can compound environmental requirements. For example: 1) asbestos; 2) poly by biphenyls and their ethers, polybrominated phenols; 3) polychlorinated biphenyls; 4) short-chain (C10 ~ C13) chlorinated paraffins. In addition, the cable insulation and sheath materials should also choose environmentally friendly materials, such as low-smoke halogen-free materials.
