Our special PVC (YA and YM) are used for insulation and sheathing purposes. PVC type YM sheath material has good mechanical characteristics and high flexibility. It provides both beginner-friendly explanations and advanced engineering insights to help professionals choose the correct cable. Several common cable outer sheath materials are PVC, PE, LSZH, AT and rodent-proof sheath materials. It has good performances, good chemical resistance and weathering resistance, low cost, low flammability, and can meet the. Both network cables and fiber optic cables have different cable jackets to choose from. Below, we will introduce several of the most common types of cable jacket material. LSZH (Low Smoke Zero Halogen) jacket is an outer sheath made of environmentally. Whether you are designing and manufacturing a new cable or simply choosing an existing one for data, power, fiber optics, or industrial automation, the outer sheath (jacket) is much more than just a speaking cover to the eye; it is, in fact, an important job holder in mechanical protection. What is a Cable Sheath? More Than Just a "Protective Layer" A cable sheath is the outermost component of the cable structure, primarily made of high-molecular polymers, wrapping around the insulation layer to form "double protection" for both the internal conductors and the insulation.
