Detailed description of LSZH cable components

Conductor: The conductor is the core of the cable and is typically made of copper or aluminum. It carries the electrical current and is usually insulated with a layer of thermoplastic or thermoset material.

Insulation: LSZH cables use insulation materials that are low smoke and zero halogen, hence the name “LSZH”. These materials are carefully chosen to minimize the release of hazardous smoke and toxic fumes during a fire. Thermoplastic materials, such as polyethylene (PE) and polypropylene (PP), or thermoset materials, such as cross-linked polyethylene (XLPE) or ethylene propylene rubber (EPR), are commonly used as insulation in LSZH cables. These materials have lower smoke emission and do not contain halogens, which are known to be harmful to human health and the environment.

Jacket: The jacket is the outer protective layer of the cable, and it is also made of LSZH materials. The jacket is responsible for providing mechanical protection, as well as resistance to environmental factors such as moisture, sunlight, and chemicals. LSZH jacket materials are typically made from thermoplastic or thermoset polymers that do not contain halogens, such as polyvinyl chloride (PVC) or low-smoke polyolefin (LSPO).
