Problems solved by technology

However, fireproof wires and cables generally have the following disadvantages: insufficient strength, poor flame retardant effect, poor insulation, and lack of certain ductility, resulting in easy damage to the cable when it is pulled, and the weight is heavy, which places a large load on the cable. , Among the many current cable inventions, the structure is complex, the cost is high, the bending strength and elongation at break cannot meet the needs, and there is no cable with good comprehensive performance and multiple functions

Embodiment 1

[0026] First, make the cable core layer, at least 6 high-purity copper monofilaments are precision drawn, annealed at constant temperature and pressure, and then tightly pressed to form a cylindrical copper conductor, which is insulated with inorganic mineral phlogopite tape, and then bonded with polymeric silicon for fire prevention agent and glass fiber mesh cloth to make a fireproof functional cloth, wrap the fireproof functional cloth on the cable core layer, and finally cover the PVC sheath layer containing glass fiber on the fireproof functional cloth, and add Abrasion resistant coating.

Embodiment 2

[0028] Firstly, the cable core layer is made, and at least 6 high-purity copper monofilaments are precisely drawn, annealed at constant temperature and pressure, and then tightly stranded to form a cylindrical copper conductor, which is insulated with inorganic mineral phlogopite tape, and then coated with SILRES® BS 6920 and SILRES® BS6921 silane-based fireproof adhesive and glass fiber mesh are used to make fireproof functional cloth, and the fireproof functional cloth is covered on the cable core layer, and finally the fireproof functional cloth is covered with PVC sheath containing glass fiber. Sheath layer, PVC sheath layer is added with reinforced mesh, and a chemical corrosion resistant coating is added on the sheath layer.

Abstract

The invention discloses a high-strength multi-performance wire cable. The high-strength multi-performance wire cable comprises a cable core, a coating layer, a functional layer and an outer sheath, the cable core layer is internally provided with at least one cable core, and a filler is filled between the cable core and the coating layer; and the outer side of the cable core layer is provided witha coating layer. A functional layer is arranged outside the coating layer, the functional layer is composed of a functional material and an adhesive, the functional layer is coated with an outer sheath, and the coating layer and the outer sheath contain at least one layer containing modified reinforcing fibers. According to the cable, the functional layer composed of the reinforcing net and the fireproof glue is contained, the cable has very good mechanical performance and electrical performance, the cable is not prone to deformation and more stable in form, multiple functional materials canbe added into the fireproof glue layer, and the service life of the cable can be greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-strength multi-performance electric wire and cable. Background technique [0002] Cables with good market and literature records generally have the following advantages: 1. Fire resistance. The two materials copper and magnesium oxide used in mineral insulated cables are inorganic substances. This kind of cable will not burn or support combustion, and can continue to operate under conditions close to flames. The copper sheath melts at 1083°C, while the magnesium oxide insulation solidifies at 2800°C. 2. High operating temperature, mineral insulated cables can withstand continuous operating temperature up to 250°C. However, in an emergency, the cable can continue to operate for a short period of time at a temperature close to the melting point of the copper sheath. 3. Long service life. The inorganic materials used in mineral insulated cables can ensure the stability, lon...
