Single-Core ECG Cable-Medical TPU

1. Material and Structural Design

• Conductor: 26AWG specification, composed of 25 strands of 0.10mm TC copper wire + nylon twisting (twist pitch: 10±2mm), ensuring stable signal transmission and resistance to bending.

• Insulation Layer: HDPE (High-Density Polyethylene) material with a transparent design, outer diameter of 1.2±0.05mm, providing excellent electrical insulation.

• Dual Shielding Structure:

• Inner Semiconductor Layer: C.PVC material, 0.20mm thickness, effectively reducing signal interference.

• Outer Shielding Layer: Braided with 60±3 strands of 0.08mm TC copper wire, shielding efficiency >95% (right-handed direction), further enhancing anti-electromagnetic interference capability.

• Sheath: TPU-5040 material (hardness: 75A±3), cool grey 4C matte finish, 0.35mm thickness, combining flexibility, abrasion resistance, and chemical corrosion resistance.

2. High-Performance Specifications

• Electrical Performance:

• Conductor resistance ≤0.15Ω/m (@20°C), ensuring low-loss signal transmission.

• Insulation resistance ≥10,000MΩ·m (DC500V), dielectric strength up to AC1000V (leakage current ≤0.25mA/3m).

• Noise <200μV/1M, guaranteeing high-precision medical signal acquisition.

• Mechanical Performance:

• Tensile strength >5KG, robust against pulling forces.
