1. Requirements for cable environment

 

Natural environment: Rechargeable car cable is exposed to sunlight, humidity and freezing for a long time, so the cable needs to be UV resistant and low temperature resistant. China covers a wide area and needs to meet the requirements of different regional conditions. Artificial environment: Dragging, twisting, bending, stretching and other phenomena will inevitably occur during the charging process, which is easy to cause mechanical damage. Therefore, it is necessary to reduce the bending stress and increase the softness of the cable. In the use of the process may also cause corrosion of the acid base liquid, so it needs to have excellent resistance to change.

 

2. Functional requirements

 

In addition to charging, electric vehicles also need communication and automatic control when necessary.

 

3. Safety requirements

 

Ev charging process time is short, high current intensity, high frequency of use, to ensure good insulation, but also requires that the material has a certain temperature resistance, anti-aging performance, and halogen-free flame retardant and low smoke density when burning.

 

Cable sheath refers to the outermost layer of the cable, also known as the outer quilt. Play the role of isolating internal insulation layer and the outside, prevent insulation from moisture, so that the internal mechanical damage. Therefore, the cable in the use of the sheath material has strict requirements.

 

TPU (thermoplastic polyurethane elastomer) is a kind of special elastomer with wide hardness range and good elasticity and toughness under high hardness. In addition, TPU has a low specific gravity of only 1.0~1.2g/cm3, so it is more economical to produce more products with the same weight.

 

Charging pile cable TPU sheath generally refers to polyether type TPU, which has better strength, hydrolysis resistance and low temperature performance.

 

1. In terms of mechanical properties, the tensile strength of polyether TPU is far superior to that of other sheath materials, above 25Mpa; The elongation is also above 500%, with good bearing capacity, impact resistance and shock absorption performance;

 

2. In terms of temperature performance, TPU has better low temperature resistance, which can reach -50℃, completely satisfying the severe cold environment in the north;

 

3. The tear strength greater than 80kN/m can effectively prevent the sheath from cracking;

 

4. TPU sheath is halogen-free and flame retardant, which will not pollute the environment.

 

5. TPU is also extremely superior in bending resistance, wear resistance, oil resistance, hydrolysis resistance and weather resistance.

 

To sum up, from the data comparison of different sheath material performance, polyether TYPE TPU as the charging cable sheath material does have great advantages.

On March 26, the Ministry of Finance, the ministry, the Ministry of Science and Technology, development and reform commission jointly issued "about further perfecting fiscal subsidy policy of new energy automobile application notice, clear according to the new energy automobile scale, factors such as cost reduction, and subsidies TuiPo exit regulation, reduce passenger car new energy, new energy bus, new energy truck subsidies standards, promote the industry evolution, prevent market ups and downs.

 

In the 2019 subsidy policy, new energy vehicles with a range of less than 250 kilometers will no longer receive subsidies, while subsidies for other models will also be sharply reduced, and higher technical standards will be set for vehicles. At the end of the three-month transition period, local governments will no longer subsidize the purchase of new energy vehicles and instead use the money to support charging infrastructure.

 

The main factors restricting the development of the new energy automobile industry are all kinds of obstacles in the use process, such as the convenience of charging infrastructure and the restriction of the existing urban management laws and regulations on the development of new energy automobiles. In view of this, the government has reduced subsidies and instead used funds to support charging infrastructure to meet the demand for new energy vehicle development.

Type polyether TPU sheathed cable effectively solves the traditional halogen free wire in flame retardant, soft, and other physical properties between the difficult technical problem to balance, namely on the basis of flame retardant grades, implementation of soft wire materials, and other physical indicators achieve a good balance between all reached the international standard type polyether TPU performance is good, the market price is also high. However, due to its excellent performance, the thickness of cable sheath TPU material of the same specification is only about half that of other materials, and the good economy, appearance and long service life of the cable are favored by most customers at present. In the future, TPU has a very broad development prospect.
