Special-shaped flat aluminum alloy conductor cable for new energy automobile

Abstract

The invention discloses a special-shaped flat aluminum alloy conductor cable for new energy automobile. The special-shaped flat aluminum alloy conductor cable comprises a center conductor and an insulation layer; the center conductor is a flat conductor compressed by annealing aluminum alloy, the aluminum alloy is prepared from the following raw materials in parts by weight: 25-35 parts of aluminum, 0.4-0.6 part of iron, 0.06-0.08 part of silicon, 0.15-0.3 part of copper, 0.02-0.05 part of magnesium, and less than 0.3 part of impurity; the insulation layer is prepared from crosslinking TPE material, and the crosslinking TPE material is prepared from the following raw materials: 25-35 parts of SEBS, 20-30 parts of polypropylene, 20-30 parts of phosphorous-nitrogen system fire retardant, 5-10 parts of nano-silicon dioxide, 5-15 parts of naphthenic oil, 5-10 parts of crosslinking agent, 2-5 parts of lubricant, 2-3 parts of master batch, and 0.2-1 part of antioxidant. The conductor cable disclosed by the invention has excellent tension strength, elongation at break and tearing strength. Compared with the existing copper cable, the cost is lower and the mass is lighter in the premise ofguaranteeing the electric property.

Description

technical field [0001] The invention relates to the technical field of automotive cable structures, in particular to a special-shaped flat aluminum alloy conductor cable for new energy vehicles. Background technique [0002] The core technology of new energy vehicles is called "three electrics", namely motor, electric control and battery. Among them, the motor is the core technology of electrification. On the one hand, it must have extremely high efficiency. Taking the general-purpose 30H motor as an example, the highest efficiency can reach about 97%. Compared with the 30% of the engine, not only the peak efficiency is high, but also the full-time Higher operating efficiency, with the famous "Double 80", that is, the efficiency of more than 80% of the operating conditions is higher than 80%. This concept is far impossible to achieve in traditional gasoline and diesel vehicles; on the other hand, high power density, For new energy vehicles, due to the addition of drive moto...

Among them, the motor is the core technology of electrification. On the one hand, it must have extremely high efficiency. Taking the general-purpose 30H motor as an example, the highest efficiency can reach about 97%. Compared with the 30% of the engine, not only the peak efficiency is high, but also the full-time Higher operating efficiency, with the famous "Double 80", that is, the efficiency of more than 80% of the operating conditions is higher than 80%. This concept is far impossible to achieve in traditional gasoline and diesel vehicles; on the other hand, high power density, For new energy vehicles, due to the addition of drive motors and batteries, the layout of the vehicle is even more difficult. Due to the high power density of the motor with flat wires, motors with high process difficulty mainly based on flat wires become a must. , but it has also become a threshold that many companies cannot cross in the short term
