Problems solved by technology

[0002] At present, the scale of domestic subway construction is showing a steady upward trend, and the demand for cables is also gradually increasing. Due to the damage of external rodent ants, ultraviolet rays, or oil pollution to cables, the quality requirements for cables are also gradually increasing. Cables need Properly insulated and shielded to prevent the cable from flowing radially from the conductor to the surrounding ground or water, this leakage current causes significant power loss

Abstract

The invention discloses an oil-resistant ultraviolet-proof B1-level direct-current power cable. The cable comprises a conductor, an insulating layer, a waterproof layer, a barrier layer and a sheath layer. The insulating layer wraps the conductor. The insulating layer is coated with the waterproof layer. The barrier layer wraps the waterproof layer. The barrier layer is coated with the sheath layer. The sheath layer is made of a halogen-free low-smoke flame-retardant polyolefin material, so that the cable has the characteristic of oil resistance, can be placed in water for a long time, can beused in places with sunlight for a long time, can be prevented from being bitten by mice and decayed by termites, does not generate harmful gas and drips during combustion, and can meet the requirements of ROHS.

Description

technical field [0001] The invention relates to a cable, in particular to an oil-resistant and ultraviolet-proof B1-level DC power cable. Background technique [0002] At present, the scale of domestic subway construction is showing a steady upward trend, and the demand for cables is also gradually increasing. Due to the damage of external rodent ants, ultraviolet rays, or oil pollution to cables, the quality requirements for cables are also gradually increasing. Cables need Properly insulated and shielded to prevent the cable from flowing radially from the conductor to the surrounding ground or water, this leakage current causes significant power loss. [0003] In order to avoid the external corrosion of the cable, it is necessary to improve the external protective insulation of the cable to meet the requirements of quality and safety. Contents of the invention [0004] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, propos...
