Description

Flame-retardant polyvinyl chloride insulating net wire

Technical Field

The utility model belongs to the technical field of the net twine production technique and specifically relates to fire-retardant type polyvinyl chloride insulation net twine.

Background

Mesh wires, typically made of metal or glass, may be used to transmit information within the network. There are three types of network cables in common use: twisted pair, coaxial cable, and fiber optic cable (optical fiber). Twisted pair is a data transmission line made up of many pairs of wires. It features low cost and wide application. Twisted pair wires are used to connect RJ45 crystal heads, and there are two types of STP and UTP, UTP being commonly used. The twisted pair is made up of four pairs of copper conductors twisted over each other with an insulating material and wrapped in an insulating sheath.

However, the existing network cable has the defects of poor sheath waterproof effect, poor flame retardant effect and single-layer insulating layer, and specifically comprises the following steps: (1) The waterproof performance is poor, the water is only prevented through the sheath on the surface of the network cable, and once the sheath is seeped or damaged, the line fault is easily caused; (2) The flame retardant effect is general, the flame retardant jacket is generally adopted for flame retardant in the prior art, however, the flame retardant jacket is adopted only for flame retardant, so that the flame retardant jacket cannot prevent a fire from fusing the flame retardant jacket, or the fusing time is extremely short, and further the user is influenced to seek help from the outside; (3) Generally, a single-layer insulation arrangement is adopted, and during the bending and bending use of the network cable, the inner insulation layer is likely to be broken, so that the mutual interference between the wires is caused.
