Novel low-smoke, halogen-free and non-toxic environment-friendly electric wire optical cable

Abstract

The invention discloses a novel low-smoke, halogen-free and non-toxic environment-friendly electric wire optical cable. The optical cable comprises a protective sleeve, conductor cores, vibration damping devices and a clamp, wherein the conductor cores are uniformly mounted on an inner wall of the protective sleeve; a low-smoke halogen-free flame-retardant filler is uniformly filled between an interior of the protective sleeve and outer surfaces of the conductor cores; the vibration damping devices are uniformly mounted on an outer surface of the protective sleeve; a shell is mounted on the other ends of the vibration damping devices; the shell is disposed in an annular shape; the clamp is mounted on an outer surface of the shell; a circular ring fixing block is mounted at top ends of twosides of the clamp; an internal thread is horizontally disposed at a bottom end of an intermediate position inside the circular ring fixing block; and a fastening bolt is horizontally mounted at an interior of the internal thread. The novel low-smoke, halogen-free and non-toxic environment-friendly electric wire optical cable enables the electric wire cable to emit less smoke when the cable is burned, the acid gas is less released, and the flame-retardant effect is good, and the electric wire optical cable is unlikely to directly harm the human body.

Description

technical field [0001] The invention relates to the technical field of electric wire and optical cable, in particular to a novel low-smoke, halogen-free, non-toxic and environment-friendly electric wire and optical cable. Background technique [0002] With the continuous development of society and the continuous advancement of digital information, the demand for wires and cables is increasing. Therefore, there are many types of wires and cables on the market, which basically meet people's needs. [0003] Most wires and cables contain polyolefin polymer materials. When a fire occurs in the surrounding environment, the flame will quickly spread along the wires and cables to the entire line, resulting in the spread and expansion of the flame. Therefore, flame-retardant wires and cables containing flame retardants should be selected , Halogenated flame retardants are widely used because of their small addition amount and remarkable flame retardant effect. [0004] However, this...
