Single-core cable for new energy single-rail railway system

Abstract

The invention discloses a single-core cable for a new energy single-rail railway system. The single-core cable comprises a conductor, wherein a halogen-free low-smoke flame-retardant irradiation cross-linked polyolefin insulating layer, a glass fiber band-added ceramic silicone rubber belt fireproof layer, a tinned copper wire braided shielding layer, a nano silicon waterproof glue filling layer,an aluminum alloy tape interlocking armor layer and a halogen-free low-smoke flame-retardant irradiation cross-linked polyolefin sheath layer are sequentially coated on the outer side of the conductor; the structure design is reasonable, and the conductors are regularly twisted by adopting a tin-plated soft copper wire small gauge in a layered mode; the twisting direction of the outermost layer isa left direction, and the twisting pitch of the middle layer is larger than the twisting pitch of the outermost layer; the conductor structure is optimized and designed, so that the conductor is stable in structure, round and compact, not prone to loosening, and capable of being repeatedly bent and dragged without deformation. The glass fiber band-added ceramic silicone rubber belt fireproof layer, the nano silicon waterproof glue filling layer and the aluminum alloy tape interlocking armor layer are added, so that the performances of fire resistance, water resistance, compression resistance,tensile strength and distortion resistance of the cable are greatly improved.

Description

technical field [0001] The invention relates to the technical field of new energy public transportation, in particular to a vehicle internal wiring system, an electrical control system, a power storage system and a single-core cable for a drive system for a new energy monorail transportation system. Background technique [0002] With the development of the city, more and more traffic pressure is constantly presented in front of people. Monorail transportation system is an important part of urban transportation system, which has the advantages of saving land area and alleviating traffic pressure, and has strong adaptability to complex terrain.

Problems solved by technology

[0003] An important part of monorail transportation, "cloud rail transit" is the fastest-growing technology in recent years. The domestic cloud rail transit developed and manufactured by BYD has been operating in many cities, and the technology has become mature. However, the wiring system used by the vehicles of the cloud rail system There are no dedicated products yet, most of which use cables for railway rolling stock. This type of product can meet the needs of railway rolling stock. However, cloud rail is a new type of transportation technology developed in recent years. Its unmanned driving, precise automatic control, and vehicle Miniaturization requires its wiring system to be more stringent, and the product has electromagnetic compatibility, temperature resistance, corrosion resistance, aging resistance, miniaturization, etc.

Existing products cannot meet the above special requirements, which requires the matching of special products on the agenda
