Thin-Walled Styrene-Based Thermoplastic Elastomer Insulated Automotive Wire (QB-C-TPES) with Rated Voltage DC 60V/AC 30V and Heat Resistance 125℃
1. Introduction
The thin-walled styrene-based thermoplastic elastomer insulated wire is used as the raw wire for automotive low-voltage circuit harnesses;
It is heat-resistant, has excellent flexibility and good bending resistance;
Temperature resistance class — Class C: -40℃ to 125℃;
Rated voltage — DC 60V/AC 30V.
2. Material/Structure
· Conductor: Bare or tinned (X) copper wire with regular stranding (A), irregular bunch stranding (B) or flexible stranding (C);
· Insulation: Coated with styrene-based thermoplastic elastomer.
3. Standard/Specification
Performance is in accordance with GB/T 25085-2010, and color and model are in accordance with QC/T 414-2016.
