New energy charging infrastructure material characteristics standards

According to the demand specific cable specifications refer to the manufacturer's cable standards.

Oil resistance: when gasoline 23℃, 20h, the maximum outside diameter change rate is less than 15%; when for diesel 23℃, 20h, the maximum outside diameter change rate is less than 15%; when for motor oil 23℃, 20h, the maximum outside diameter change rate is less than 15%. In terms of oil resistance, the outer diameter change rate is between 15%-40% by temperature and duration.

Tear and crack resistance, according to the test report, the value in greater than 15N/MM-40N/MM.
Resistance to bending and winding, can be back and forth tens of thousands of times, 2.5kv core pressure resistance.
Weather resistance. 

Water resistant, acid and alkali resistant 
Water, 80°C 168H, acid and alkali 23°C 186H after immersion mechanical properties change rate is less than 30%

Abrasion and crush resistance
Wire applicable: not greater than 6mm2 scraping abrasion test greater than 6mm2 dragging abrasion test.
Scraping and grinding: use steel needle, apply vertical force to do circular motion, record the number of cycles to make the conductor exposed.
Drag grinding: using sandpaper, record the length of the abrasive belt that exposes the conductor.
Flexibility
Below 80A, even 65-70A.

High and low temperature resistance: temperature alternation: temperature -40℃ to 100℃ as an alternation, humidity control at 80%-100%.
Judgment conditions: no cracking, voltage resistance 1KV (dipped in salt water for 10 minutes).
Low temperature performance: winding: general -40 ℃, thick-walled wire can be negotiated between the two sides -25 ℃

Impact: GB/T25085
Heat aging: (1) 3000h long-term aging: 125 ℃, 3000h, after taking out 16h
Judgment basis: no cracking, voltage resistance 1KV (dipped in salt water for 10 minutes)
240h short term aging: 150℃,240h, take out and do -25℃ winding experiment directly for 4h
Judgment basis: no cracking, voltage resistance 1KV (10 minutes in salt water).

Environmental protection flame retardant
Halogen-free: chlorine, bromine content less than 1500ppm
Low smoke: Ph>4.3, electrical conductivity 60%
Flame retardant: IEC60332-1 IEC60332-3C VW-1 tilt 45° burning
