High-temperature-resistant high-pressure-resistant odorless explosion-proof cable for new energy automobile

Abstract

The invention discloses a high-temperature-resistant high-pressure-resistant odorless explosion-proof cable for a new energy automobile. The cable comprises a central conductor, an insulating layer, a shielding layer and a sheath layer. The central conductor is an annealed bare copper or tin-plated stranded conductor which is formed by interlacing regularly or irregularly; the periphery of the central conductor is tightly coated with the insulating layer; the periphery of the insulating layer is tightly coated with the shielding layer; the periphery of the shielding layer is tightly coated with the sheath layer; the insulating layer and the sheath layer are both made of a special high-temperature-resistant odorless explosion-proof silicone rubber ceramic material, wherein the raw materials of the insulating layer and the sheath layer comprise 5-18 parts of methyl silicone rubber, 3-23 parts of methyl vinyl silicone rubber, 8-31 parts of styryl methyl silicone rubber, 2-6 parts of silicon dioxide, 3-8 parts of aluminum oxide, 1-5 parts of zinc stearate, 1-7 parts of a flame retardant, 2-7 parts of a fire retardant, 1-6 parts of glass powder, 3-10 parts of ceramic powder, and 3-15 parts of other additives; the weight ratio of the glass powder to the ceramic powder is 3.5: 5.8. When a vehicle catches fire, electric energy can be transmitted rapidly and accurately, personal safety is guaranteed, and meanwhile, the requirement for environmental protection is met.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-temperature, high-pressure, odorless, explosion-proof cable for new energy vehicles. Background technique [0002] When new energy vehicles (such as pure electric vehicles, hybrid vehicles, etc.) are running under load, the operating voltage, current and frequency of the vehicle will change drastically when the vehicle starts, brakes, accelerates and decelerates. At this time, the cable bears a very large current and generates a lot of heat in a short period of time. It may be accompanied by circuit aging or other reasons, which may cause the vehicle to catch fire, especially the fire at the battery part. personal injury, or even endanger the lives of passengers. In addition, the vulcanizing agent in traditional silicone rubber materials has a strong smell, which not only endangers the health of passengers, but also is not conducive to environmental protection.
