Common material standard of charging cable of charging pile

China [CN]

As we all know, the core of the development of new energy vehicles is the problem of charging piles, and the "new infrastructure" charging pile trillion market is riding the wind and waves.

Now, for the first time, charging piles have been included in a government work report. We will strengthen the development of new types of infrastructure (" new infrastructure "), develop next-generation information networks, expand 5G applications, build charging piles, promote new-energy vehicles, stimulate new consumer demand and boost industrial upgrading. The following is the standard for material properties of new infrastructure:

Oil resistance, when gasoline 23℃, 20h, the maximum outside diameter change rate is less than 15%; When it is diesel oil at 23℃ for 20h, the maximum outer diameter change rate is less than 15%. When the oil is 23℃, 20h, the maximum outer diameter change rate is less than 15%. In terms of oil resistance, affected by temperature and time, the change rate of outer diameter is between 15% and 40%.

Tear resistance and cracking resistance, according to the test report, the value is greater than 15N/ mm-40N /MM.

Bending resistance, tens of thousands of times back and forth, 2.5kV core wire pressure resistance.

Wait,

Resistant to water and acid and alkali

After soaking water at 80°C for 168H and 23°C for 186H, the change rate of mechanical properties is less than 30%

Wear and roll resistance

Wire application: no more than 6mm2 scraping experiment larger than 6mm2 drag grinding experiment.

Scraping: use a steel needle to apply a vertical force to make a circular motion, and record the number of cycles that expose the conductor.

Drag and grind: with sandpaper, record the length of sand tape that exposes the conductor.

soft

Below 80A, even 65-70A.

High and low temperature resistance

Temperature change: temperature -40℃ to 100℃ for an alternating, humidity control in 80%-100%.

Judgment conditions: no cracking, withstand voltage 1KV (immersed in salt water for 10 minutes).

Low temperature performance: winding: generally -40℃, thick wall wire can be negotiated by both parties -25℃

Impact: GB/T25085

Thermal aging: (1) 3000h long-term aging: 125℃,3000h, after taking out 16h

Judgment basis: no cracking, withstand voltage 1KV (immersed in brine for 10 minutes);

240h short-term aging: 150℃,240h, take out directly to do -25℃ winding experiment for 4h

Judgment basis: no cracking, withstand voltage 1KV (immersed in salt water for 10 minutes).

Environmental protection flame retardant

Halogen-free: chlorine, bromine content less than 1500ppm

Low smoke: Ph>4.3, conductivity 60%

Flame retardant: IEC60332-1 IEC60332-3C VW-1 inclined 45° combustion.
