Wire and cable companies consider eco-friendly cables to be free of heavy metals such as lead, cadmium and mercury. Free of brominated flame retardants. Environmental performance test approved by SGS, in line with EU Environmental Protection Directive (RoSH), higher than its index requirements. No harmful halogen gas, no corrosive gas, small calorific value during combustion, no soil pollution wire and cable. There is no hard and fast line between "wire" and "cable." Usually the products with less core, small diameter and simple structure are called wires, those without insulation are called bare wires, and others are called cables. Conductors with a large cross-sectional area (greater than 6 square millimeters) are called large conductors, conductors with a smaller area (less than or equal to 6 square millimeters) are called small conductors, and insulated conductors are also called distribution conductors.
1. Flame retardant and fire resistance. Wire and cable company believes that the flame retardant performance of environmental protection wire and cable fully meet the national fire standards, wire and cable in the event of electrical fire is not easy to burn. At the same time, in the case of continuous combustion, it can ensure the normal operation of the circuit system in a certain period of time, and reduce the spread of the flame after the burning of the wire and cable to a greater extent.
2. No pollution. Wire and cable companies believe that the insulation materials and sheathing materials used by environmental protection wires and cables are green and environmentally friendly materials, which not only ensure the stable electrical performance and physical and mechanical functions, but also ensure the safety performance of wires and cables, and avoid the "secondary pollution" caused by the incineration of discarded wires and cables.
3. The toxicity of wire and cable is low. Wire and cable company believes that due to the particularity of the raw materials used for environmental protection wire and cable, the insulation layer and outer sheath of wire and cable do not contain lead, cadmium and other harmful heavy metals, so as to ensure our own health and safety in use to a greater extent.
4. Wires and cables do not decompose corrosive gases. Wire and cable companies think that environmental protection wire and cable using new special materials without pollution, in the process of use will not produce a variety of toxic gases due to high temperature and other reasons, less harm to equipment and instruments, so it has environmental protection characteristics. Green materials with special molecular structure are adopted to ensure low water absorption. Special UV absorbent makes the product have good UV protection function. Ensure the safety of such products and extend the service life.
Wire and cable companies believe that with the growing concern about the environment and various environmental policies enacted in many countries, people are more inclined to use green cables. Low smoke halogen-free flame retardant cable material is one of the more popular environmental protection cables. Despite the increasing demand for green cables in the Chinese market, the country still has a long way to go in terms of relevant policy formulation and mandatory application compared with developed countries. China should raise the standard of green cable as soon as possible.
