Now, with the development of urbanization, there are many XLPE insulation cables, low smoke halogen free insulation cables. For example, nowadays solar cables are in great demand. Many high-quality solar cables will use XLPO/XLPE insulation and low smoke halogen free sheath. After receiving solar cables, many customers conduct a combustion test and find that the cables can be burned, and then ask us why low smoke halogen free cables will catch fire.
In fact, low-smoke and halogen-free does not mean that the cable will not catch fire, but the smoke emitted and the light transmittance will be better than traditional PVC. Traditional PVC as a sheath material will release a large amount of smoke after being heated or burned, and its light transmittance is below 10%, which will cause great damage after a fire accident. Therefore, solar cables generally use low-smoke halogen-free sheaths. Low smoke halogen free cables emit less smoke when burned, and their light transmittance is generally above 80%. At this time, the vision is clear, but ordinary PVC cables The amount of smoke is the largest, and its lowest light transmittance is about 10-20%, which is a state without vision.
Therefore, low smoke halogen free cables are not cables that cannot be burned, but safety cables that can reduce disasters to a minimum.
