Environmentally friendly electric wires are those whose materials are environmentally friendly. The materials include insulation, conductor materials, and shielding materials. Insulation such as polyvinyl chloride (PVC), irradiated cross-linked polyvinyl chloride (XL-PVC), irradiated cross-linked polyethylene (XL-PE), low smoke and halogen-free (Halogen-free), silicone rubber, fluorine plastic high-temperature wire and so on. The environmental protection of insulation materials, at present, is mainly the EU environmental protection directive and the EU environmental protection regulations on children's toys require the non-6P (Non-6P), that is, no phthalates. And now the most environmentally friendly is low smoke halogen-free, completely free of halogen elements.

  The most common conductor material is copper. Copper has a bare copper (called brass, red copper), tinned copper, silver-plated copper wire, etc., these types of essentially still copper, just the surface of other substances coated. Now on the market there are copper clad aluminum, copper clad just do the conductor. If the electrical performance requirements are high natural copper is the best. Conductor of environmental protection is mainly required to be free of heavy metals.

  Environmentally friendly cable means no lead, cadmium, hexavalent chromium, mercury and other heavy metals, no brominated flame retardants, by the SGS recognized testing agency on environmental performance testing, in line with the EU environmental directives and higher than its index requirements. It does not produce harmful halogen gas, does not produce corrosive gas, has less fever when burning, and does not pollute the soil silicone wire cable.

  Main technical indicators.

2, the highest long-term allowable working temperature of the cable conductor should not exceed 70, 90, 125 ℃ respectively.

3, the cable burning smoke density in line with GB/T17651-1998 (equivalent to IEC1043) standard requirements, light transmission rate ≥ 60%.

4, the cable halogen acid content test in line with GB/T17650-1998 (equivalent to IEC754-2) standard requirements.

(1) PH value ≥ 4.3

(2) conductivity ≤ 10μs/mm

5, led silicone cable cable flame retardant performance in line with the requirements of GB/T12666-1990

6, the toxicity index of the cable ≤ 3.
