Product Detail

Product Features

Weather resistance Low smoke zero halogen sheath cable material can withstand the effects of daily meteorological conditions, such as sunlight, rain and humidity, so it is suitable for indoor and outdoor applications.

High fire resistance Low smoke zero halogen sheath material usually have high fire resistance, which can protect the insulation material inside the cable in a fire and prevent the spread of fire.

Low smoke combustion Low smoke zero halogen sheath cable material produces less smoke in the event of a fire, which helps to improve the safety of personnel evacuation.

Low toxicity Low smoke zero halogen sheath cable material usually has low toxicity, even when burning, it produces less toxic gas, helping to reduce the risk of toxicity in fire.

Environmental protection The zero halogen composition makes this sheath material more environmentally friendly and reduces the damage to the atmospheric ozone layer.

Scope of Use

Cable and optical cable, coaxial cable, network cable, elevator cable, etc.
