Halogen-free (LSOH) cables are divided into radiation cross-linked XLPE and non-irradiated PE. PVC cables contain halogen. As environmental protection requirements become higher and higher, most manufacturers require halogen-free (LSOH) cables.

From the appearance point of view, the PVC cable feels soft and smooth, while the LSOH cable feels rough and hard due to the flame retardant compound inside. LSOH cables are more beautiful than PVC cables.

From the point of view of use, LSOH cable is environmentally friendly, has a long service life, is heat-resistant and flame-retardant, and its performance will not change even after long-term use or a high-temperature environment. Low-smoke halogen-free (LSOH) cables are mainly used in places where power plants, steel plants, subways, and substations have high requirements for cable power, as well as hospitals, schools, shopping malls and other densely populated places.

From the price point of view, LSOH cables are about 10% to 20% more expensive than PVC cables.
