Graphene composite shielding anti-interference power cable for environment-friendly intelligent high-speed rail and fabrication method of graphene composite shielding anti-interference power cable

Abstract

The invention discloses an environment-friendly intelligent high-speed rail graphene composite shielding anti-interference power cable and a preparation method thereof. The insulation layer and the insulation shielding layer form an insulated wire core; the outer layer of the insulating wire core is overlapped and wrapped with a metal inner shielding layer; The aluminum-plastic composite tape layer wrapped longitudinally is extruded with a polyethylene moisture barrier layer; the outer gap of the moisture barrier layer is wrapped with a double-layer tantalum steel alloy tape armor layer, and the outermost layer of the cable is extruded with an outer sheath. The invention has good insulation properties, mechanical properties, power transmission, anti-magnetic interference, lightning protection, flame retardant, halogen-free, low-smoke environmental protection, waterproof, corrosion resistance, radiation resistance and other properties; the structure is reasonable, the comprehensive performance is superior, and the product The performance index is superior to the requirements of international standards; and can produce good social and economic benefits.

Description

technical field [0001] The invention relates to the field of high-speed rail transportation power cables, in particular to an environment-friendly intelligent high-speed rail graphene composite shielding anti-interference power cable and a manufacturing method, which are suitable for high-speed rail power control and ensure the normal operation of the high-speed rail transmission and transformation grid power transmission system. Background technique [0002] With the wave of global economic development and recovery, high-speed rail will enter a new wave of infrastructure construction. The role of high-speed railway in stimulating regional economy has been recognized, and it can promote exchanges and balanced development between regions. At the same time, after the financial crisis, the global economic growth rate has declined, and infrastructure bottlenecks have seriously affected short-term and long-term economic growth. Developed countries are faced with the need for inf...

Problems solved by technology

[0005] At present, there is no professional manufacturer of this product in China; the traditional production technology is backward, the structural design is unreasonable, and the yield is low; and in recent years, the requirements for the safety, anti-electromagnetic interference and electromagnetic resistance of high-speed railway cables are getting higher and higher, resulting in Due to the existing technology, many manufacturers cannot design and produce intelligent environmental protection medium voltage power cable products that meet the technical requirements

And the production process has the following problems: 1, the processing capacity is large, and the production cost is high

2. It is not conducive to laying and management, and the risk factor is large

3. Difficult assembly of finished products and long production cycle

4. The structure is unreasonable and the laying area is large
