Armoured Cable Outer Casing/Armored Conduit (4–5 Layers)
Designed for demanding cable-control applications, armored cable outer casing provides a mechanically reinforced route for push-pull cables, control cables and other flexible cable systems. The casing combines polymer protection with spiral steel-wire reinforcement to improve resistance to external mechanical loads while maintaining the flexibility required for cable routing.
Manufactured by Keli, the armored conduit can be customized in diameter, reinforcement structure, liner, outer jacket material, color and other specifications according to the cable design and operating environment. Standard configurations are available for different cable sizes, while engineered solutions can be developed for specific assembly requirements.
Armoured Cable Outer Casing/Armored Conduit Structural & Material Analysis
The armored cable outer casing features a multi-layer construction that combines an outer protective jacket, steel-wire reinforcement and an inner liner. Each layer is selected to serve a specific role in cable protection, routing and assembly performance.
This layered construction allows Keli to configure the armored conduit structure, materials and dimensions for different cable systems rather than relying on a single fixed specification.

The standard construction is available in 4–5 layers, while the total layer count can be customized from 3 to 6 layers depending on diameter, cable construction and reinforcement requirements.
Ultra-low Friction & High Smoothness
The specially developed low-friction inner liner ensures smooth, non-jamming, and low-wear operation of the inner cable, thereby enhancing the responsiveness of mechanical control.
Super Tensile & Compressive Strength
The multi-strand stainless steel armor provides excellent breaking strength. Whether in a straight line or under a large bending radius, it ensures stable axial force transmission, preventing the inner tube from deforming under compression or snapping under tension.
Excellent Flexibility & Small Bending Radius
The unique outer ring-shaped texture coupled with the metal spring skeleton gives the conduit excellent flexibility, allowing it to easily navigate complex routing in confined spaces such as automotive engine bays and chassis.
Outstanding Weather Resistance & Durability
The outer jacket boasts excellent wear resistance, high/low-temperature tolerance (-40℃~ +125℃), oil resistance, and chemical corrosion resistance. It is capable of withstanding harsh environments and offers a long service life.
Custom Armored Cable Outer Casing Manufacturing
Standard specifications do not always match the cable, installation space or operating conditions of a specific project. We provide custom armored cable outer casing manufacturing to develop the conduit around the customer’s actual requirements.
Customization can include:
- Inner and outer diameter
- Steel-wire diameter and wire count
- Number of reinforcement layers
- Liner material
- Outer jacket material
- Color and surface finish
- Length and packaging
- Cable assembly and connection requirements
Our engineers can review drawings, cable dimensions, samples or application information to determine a suitable casing structure. This approach allows the reinforcement level, liner and external protection to be matched to the actual cable system instead of relying on a one-size-fits-all specification.
