Automotive Warp-Knitted Split Braided Wire Loom

MJ FLEX STW-PET-W is a warp-knitted split wire loom with a textured wave profile for automotive harness protection. The openable structure wraps around installed wiring, follows tight bends and accommodates branch points. Its knitted geometry provides a flexible alternative to rigid conduit in interiors and protected equipment zones.

  • Why Choose STW-PET-W Braided Split Loom?

    1. Follow complex vehicle routes

    The knitted wave structure bends around corners and changing harness profiles.

    2. Speed harness installation

    Side entry fits terminated cables without pulling through a closed tube.

    3. Protect cables near panels

    Textile coverage reduces jacket wear against vehicle structures.

    4. Simplify service and branching

    The split loom opens locally for exits and maintenance.

     

    Key Features

    1. Warp-knitted wave structure

    Provides flexible textile coverage.

    2. Split wrap-around profile

    Supports side-entry installation.

    3. Automotive routing flexibility 

    Follows bends and irregular bundles.

    4. Branch-friendly construction

    Allows local wire exits.

    5. Abrasion protection

    Helps reduce cable-jacket wear.

    6. Lightweight alternative

    Avoids bulky rigid conduit in protected areas.

    7. Custom harness supply 

    Sizes, lengths and packaging can be reviewed.

    ● Note: Select the size according to the actual bundle diameter and ensure at least 35% overlap after installation.

    Typical Applications
    Dashboard harnesses
    Routes branched wiring through confined interior spaces.
    Door and seat systems
    Protects flexible harnesses around moving modules.
    Body and roof wiring
    Contains long cable runs behind trim panels.
    Industrial machinery 
    Organizes sensor wiring around frames and bends.
    Appliances
    Protects internal cable groups near housings.

    How to Select

    Measure minimum and maximum bundle diameter, branch locations and bend radius. Select a size that closes securely without flattening the knitted profile. State abrasion, movement, temperature and fluids. Use a tested FR or high-temperature grade when the project specifies those properties.

     

    Customization Available

    Nominal size - Matched to cable range.

    Knitted density - Adjusted for coverage and flexibility.

    Cut lengths - Prepared by harness zone.

    Labels and packaging - OEM kits and private labels available.

     

    Testing and Compliance

    Standard STW-PET-W is intended for mechanical cable organization and abrasion protection. Flame, temperature, automotive and chemical claims require exact construction data. Material declarations may be available for confirmed yarns.

     

    Quality Assurance

    Yarn identity - Material and color are checked.

    Knitted profile inspection - Wave consistency and defects are monitored.

    Fit verification - Closure and dimensions are checked.

    Packing release - Length, labels and quantity are confirmed.

    Frequently Asked Questions

    01. How is it different from woven wrap?
    Warp knitting creates a looped, flexible wave structure; woven fabric has a different yarn interlacing and surface.
    02. Can cables exit along the route?
    Yes. The split profile opens locally for branches.
    03. Is the standard version flame rated?
    Only when supported by test data for the exact construction.
