Flat Twisted Cable

Flat twisted cable is a cable consisting of multiple conductors twisted and arranged in parallel into a ribbon structure. It is suitable for signal transmission and power connections within computers, home appliances, and communications equipment.

Common materials for flat twisted cables are aluminum, aluminum alloy, copper, tinned copper and copper clad aluminum.

Each pair of conductors is twisted into pairs, then bonded together using heat pressing or ultrasonic bonding to form a flat ribbon.

The overall shape is a long, flat ribbon with uniform core spacing and a smooth surface, making it easy to bend and route.

Flame-retardant PVC, high-temperature resistant PE, or polytetrafluoroethylene (Teflon) extrusion coating are commonly used, providing insulation, moisture resistance, and wear resistance.

Wire Diameter and Strand Count: Customizable cross-sections and strand counts based on current requirements.
Length and Color: Customizable lengths and colors based on installation space and identification requirements.
Terminals and Interfaces: Customizable bare wire, crimp terminals, or pre-assembled connectors.
Construction: Customizable flat or semi-flat configurations.

Extrusion

Aluminum rods are heated to 400–500°C, extruded through a die into a preliminary wire shape, and rapidly cooled to ensure uniform microstructure and stable properties.

 

Wire Drawing

Aluminum wire is continuously stretched through multi-stage tungsten steel dies to reduce diameter and extend length, while also improving tensile strength and surface finish.

Annealing

Heating the aluminum wire to 360–400°C eliminates internal stresses, promotes recrystallization, and improves flexibility and subsequent processing performance.

 

Flat Twisted Cable

Arrange multiple aluminum wires in parallel and keep the width uniform.

 

Flat Stranding (Twisting)

The wires are lightly twisted along their axis to form a structurally stable flat strand. Tension control is used to ensure conductivity and mechanical strength.

 

Shaping & Finishing

The wire shape is fixed through light calendering or heat treatment. Dimensions and insulation quality are inspected to ensure product compliance with technical specifications.

 

Reeling & Cutting

The finished flat stranded wire is reeled or cut into lengths for transportation, storage, and subsequent use.

 

 

Wires are wound on plastic or wooden spools based on diameter and length. The outer layer is covered with moisture-proof film and labeled. Shock-absorbing foam or paper sheathing can be added to prevent damage.

 

 

Flat twisted cable can be shipped by sea, air, and road, supporting global delivery.
