1. 35 square copper wire, brass tinned chuck, copper tinned wire nose 2. Red copper has low resistance, stable current and strong oxidation resistance 3. Wrapped with high-quality insulation material, the power is more stable 4. Good electrical conductivity, oxidation and corrosion resistance 4. The chuck and the nose are strengthened by hydraulic pressure, so they are not easy to fall 5. LT spy nose is made of red copper, and the surface is tin-plated 6. The inner diameter of the negative electrode: 15-17mm 7. The inner diameter of the positive electrode: 17-19mm 10. Material: copper+brass+PVC
