Background

The wire and cable industry is an important matching industry for economic construction and is widely applied to various fields of national economy. In recent years, with the continuous and rapid development of economy and the advance of urbanization, the wire and cable industry keeps a higher growth speed, and the requirements of wires and cables are continuously increased. At present, with the increase of electrical equipment, some wires and cables with small sections and small outer diameters are required to be used in some high-temperature equipment, and because the wires and cables have small sections, the wires and cables are not resistant to bending and have poor mechanical properties, the wires and cables are easy to break in places needing uninterrupted reciprocating motion, and the wires and cables have low bending resistance and tensile property, short service life and high cost. It is therefore desirable to improve the bend resistance of small-section wire cables.

The common small-section wire and cable adopts a plated copper conductor, fluoroplastic insulation, and a silicone rubber or fluoroplastic or polyvinyl chloride sheath. The conductor of the electric wire and cable has poor bending resistance, while the silicon rubber sheath has good flexibility, but the mechanical property is poor, the flame retardant and acid and alkali resistant properties are common, and the electric wire and cable cannot meet the places with higher requirements. When the fluoroplastic is used as a sheath, the fluoroplastic is not good in flexibility after being used as the sheath due to the fact that the fluoroplastic is hard, and is easy to break in a reciprocating place and poor in bending resistance. When the flexible polyvinyl chloride is used as the sheath, the use requirement of a high-temperature environment cannot be met due to the limitation of the material.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an aim at exactly to above-mentioned current small cross section wire and cable compliance, resistant bending property is relatively poor, can't satisfy high temperature environment's defect, provides a soft resistant high temperature wire and cable of buckling, and small cross section wire and cable compliance is good, and is resistant buckling, high temperature resistant, and the fire resistance is good, and acid and alkali resistance is excellent, and the life of product obtains the extension.
