Three-Layer Straight-Wire Reinforced Conduit
This series of three-layer straight wire tubes (three-layer insulation sleeving) is a high-performance composite wire specifically developed for the automotive industry and high-end manufacturing. Utilizing advanced composite material forming technology, the core structure consists of a high-performance inner lining and a flexible functional coating. The inner lining is available in various engineering plastics such as PE, POM, PTFE, PA, and PBT, while the coating can be customized with insulation materials like PVC, PP, PA6, PE, TPE, and TPEE. By flexibly combining the characteristics of different materials, our product not only meets stringent automotive-grade electrical requirements but also adapts to diverse complex industrial environments.

Three-Layer Straight-Wire Reinforced Conduit Core Technical Capabilities
Three-Layer Straight-Wire Reinforced Conduit Features & Advantages
Menu-style Customizable Material Selection
With a rich matrix of inner lining and coating materials, customized conduit solutions based on temperature, friction, insulation and flexibility requirements (e.g., temperature rating, friction coefficient, insulation voltage, flexibility requirements).
Excellent Processing Adaptability
The straight-line structure combined with precise wall thickness control supports high-speed automated wire stripping, cutting, and terminal crimping, significantly boosting production efficiency for automotive wiring harnesses and control cable assembly.
Diverse Colors and Specifications
The outer coating is available in various standard colors (green, gray, blue, black, etc.) for easy production management and circuit identification; cross-sectional gauges and wall thickness tolerances are precise, meeting high-precision assembly requirements.
Custom Three-Layer Reinforced Conduit Manufacturing
We provide customized three-layer straight-wire reinforced conduit for automotive wiring harnesses, control cables and industrial equipment. Instead of using a fixed material combination, we can engineer the conduit structure according to your required dimensions, operating temperature, flexibility, friction, mechanical protection and environmental resistance.
Customized Material and Structure Options
Depending on the application, customers can specify or work with our engineers to select:
- Inner liner: HDPE, POM, PBT, PTFE and other engineering plastics
- Steel-wire reinforcement: wire diameter, wire count, material and reinforcement structure
- Outer coating: HDPE, PP, PA6, TPE, TPEE and other suitable materials
- Dimensions: inner diameter, outer diameter, wall thickness and overall conduit size
- Performance: temperature resistance, flexibility, friction, oil and chemical resistance, insulation and flame-retardant requirements
- Appearance: color and surface requirements
- Packaging: customized packaging for production, assembly and shipment requirements
