Latest company news about The uses of LSZH orange cables.

LSZH orange wire typically refers to an orange insulated wire or cable made with Low Smoke Zero Halogen (LSZH) material. LSZH is an environmentally friendly sheathing material with flame-retardant, low-smoke, and halogen-free properties, suitable for applications requiring high safety standards.

Regarding color coding, in wires and cables, orange is not usually a standard insulation color (such as yellow-green for grounding), but it may be used to identify specific applications or manufacturer coding. For example:

In some cases, an orange sheath may be used to distinguish different types of cables, such as network cables or control cables.

The specific application needs to be considered in conjunction with the actual usage scenario, for example:
Network cabling: LSZH material is often used in Category 5e and Category 6 network cables, suitable for integrated wiring systems in smart buildings, data centers, and other locations, supporting high-speed data transmission (such as Gigabit Ethernet).

Safety environments: Because LSZH material produces less smoke and no toxic halogen gases when burned, it is suitable for enclosed spaces such as subways, hospitals, and schools.

Other applications: It may also be used for instrument wiring, automation equipment, or security systems, but the color itself does not change the basic properties of the LSZH material.
