| Appellation | Good specifications √ | Explain | General specification × | Explain | ||||
| 1.Conductor | 26AWG Pure copper or Tinned copper | Good conduction and long service life | Less copper or copper-plated steel wire | Large resistance value and short service life | ||||
| 2.Nylon yarn | 250D nylon wire | Increase life | Without | Short service life | ||||
| 3.Cotton thread | 3 Cotton threads | Increase life | Without | Short service life | ||||
| 4.Core wire coverage | HDPE insulation | Long life span, which is good for signal transmission | Ordinary PVC | Short service life and large signal attenuation | ||||
| 5.GND coverage | Patented conductive HDPE | Conduction with tin foil to strengthen anti-interference | Ordinary PVC | Short service life | ||||
| 6.Tin foil | Connect the tin foil to GND | Replace metal braided shield, good anti-interference, low price, long bending life | Insulated from GND | Poor anti-interference performance | ||||
| 7.Jacket | Low temperature resistant soft material | Long service life in normal or low temperature environments | Ordinary PVC | Short service life in low temperature environment | ||||
| White and green wires twisted in pairs | Standard Twisted Wire | Enhance signal transmission | No twist | Large signal attenuation | ||||
