Rubber Cable Manufacturers
Radicab Cables is a reliable Rubber Cable Manufacturers offering flexible and durable cable solutions for industrial, commercial, construction, machinery, welding, power, and other demanding electrical applications. Rubber cables are selected where conventional cable constructions may need additional flexibility, mechanical strength, moisture resistance, or protection against demanding operating conditions.
Our rubber cable solutions are designed around the requirements of the application, including conductor configuration, insulation material, sheath construction, voltage requirement, flexibility, operating environment, and installation method. This makes rubber cables suitable for equipment and electrical systems where regular bending, movement, vibration, handling, or environmental exposure can occur.
What Are Rubber Cables?
Rubber cables are electrical cables that use rubber or elastomeric materials as insulation, sheath, or both. Depending on the cable design, materials such as EPR (Ethylene Propylene Rubber), PCP/CR (polychloroprene), silicone rubber, and other elastomeric compounds may be used for specific electrical, thermal, mechanical, or environmental requirements.
A typical flexible rubber cable can consist of a stranded copper conductor, rubber or EPR insulation around individual cores, fillers where required, and an outer rubber/elastomeric sheath.
The final construction depends on the intended application and required performance.
Rubber Cable Construction
| Cable Component | Typical Material | Main Function |
|---|---|---|
| Conductor | Annealed copper / tinned copper | Carries electrical current |
| Conductor Type | Solid, stranded or flexible stranded | Provides required electrical and mechanical characteristics |
| Insulation | EPR / elastomeric rubber | Provides electrical insulation |
| Core Identification | Colours, numbers or markings | Helps identify individual cores |
| Fillers | Compatible textile/elastomeric materials | Maintains cable shape and core arrangement |
| Inner Layer | Suitable elastomeric material | Provides additional separation/protection where required |
| Outer Sheath | Rubber / PCP / other elastomer | Protects against mechanical and environmental stresses |
Industry cable constructions include Class 1, Class 2 and flexible Class 5 copper conductors, while elastomeric insulation and sheath compounds are selected according to the required service conditions.
Why Use Rubber Cables?
Rubber cables are particularly useful where the cable needs to withstand movement, bending, vibration, handling, or demanding environmental conditions.
1. High Flexibility
Fine-stranded copper conductors combined with flexible insulation and sheath materials allow rubber cables to bend more easily than many conventional fixed-installation cable constructions.
This makes them suitable for portable tools, machinery, welding equipment, construction equipment, and other applications involving regular cable movement.
2. Mechanical Durability
The outer elastomeric sheath can provide protection against mechanical stresses such as abrasion, impact, bending, and repeated handling, depending on the selected cable construction.
3. Moisture and Environmental Resistance
Appropriately designed rubber cables can be used in damp, wet, and outdoor environments. Certain rubber and elastomeric compounds also provide resistance to oils, chemicals, ozone, weathering, and other environmental factors.
The actual resistance depends on the specific insulation and sheath compound.
4. Heat Resistance
Different elastomeric compounds offer different temperature capabilities. EPR, silicone rubber, and other specialized materials can be selected when higher thermal performance is required.
The operating temperature should always be confirmed from the specific product datasheet rather than assumed from the general term “rubber cable.”
5. Suitable for Dynamic Applications
Rubber cables are widely used where electrical equipment moves during operation. Their flexibility makes them suitable for applications involving repeated bending, dragging, winding, or repositioning.

For machinery applications, cable selection should consider:
- Required voltage
- Current carrying capacity
- Number of cores
- Conductor cross-section
- Frequency of movement
- Bending radius
- Operating temperature
- Oil or chemical exposure
- Indoor or outdoor installation
