Rubber Cable

THE rubber cables are electrical cables used for power supply and transmission of energy in installations requiring great flexibility and good resistance to mechanical stress. Thanks to their rubber insulation or thermosetting elastomers such as EPR, these cables offer excellent abrasion resistance, humidity, oils and demanding industrial environments.

They are widely used for mobile electrical equipment, Industrial machines, construction facilities, welding equipment, as well as in sectors such as energy, the maritime, mining and wind energy. Flexible rubber cables are particularly suitable for applications requiring frequent movements or severe conditions of use..

As a specialist manufacturer, ZMS CABLE produces a wide range of rubber cables compliant with international standards, including widely used types such as H07RN-F, H05RR-F et H05RN-F, as well as other elastomeric insulated industrial cables for different power levels and operating conditions.

Types of Rubber Cables Available at ZMS Cable

Soft rubber cable

THE flexible rubber cables suitable for a wide range of applications requiring great flexibility and good resistance to difficult industrial conditions.
In the industrial field, these cables are used for power supply, control and transmission of signals from various equipment. They also serve as power cables for construction machinery and equipment, such as cranes, tower cranes and other mobile equipment.
The most common types include and H07RN-F, widely used for mobile equipment and construction sites.

Structure : Fine stranded flexible copper conductor, rubber insulation (EPR or synthetic rubber) and abrasion-resistant rubber outer jacket, to humidity and oils.

Features : Very high flexibility and excellent resistance to repeated movements. Ideal for mobile equipment and demanding industrial environments.

Standards : IEC 60245, IN 50525, IEC 62067，IEC 60502，GB/T 12706-2008，ASTM B800

ZMS CABLE expert advice :
THE flexible rubber cables are particularly suitable for mobile machines, to construction sites and industrial equipment. For environments presenting significant mechanical risks (crushing or shock), the use of an armored rubber cable can provide additional protection.

Cable type	Number of conductors × section (mm²)	Driver class	Driver diameter (mm)	Insulation thickness (mm)	Outside diameter Approx. (mm)	Masse approx. (kg/km)
H05RR-F	3 × 1,5	Class 5	1,38	0,7	8,5 – 9,5	110 – 130
H05RN-F	3 × 1,5	Class 5	1,38	0,7	9,0 – 10,5	120 – 150
H07RN-F	3 × 2,5	Class 5	1,78	0,9	11,5 – 13,5	190 – 230
H07RN-F	3 × 10	Class 5	4,12	1,0	18,0 – 21,0	700 – 820
H07RN-F	4 × 25	Class 5	6,00	1,2	28,0 – 32,0	1800 – 2100
H07RN-F (extra flexible)	3 × 10	Class 6	4,40	1,0	19,0 – 22,5	720 – 860
H07BQ-F	3 × 2,5	Class 5	1,78	0,9	11,0 – 13,0	200 – 240

Armored rubber cable

THE armored rubber cables combine the flexibility of rubber insulation with metal armor designed to enhance mechanical protection in demanding industrial environments.

Stucture : Soft copper conductor, rubber insulation (EPR or equivalent), inner sheath, metal armor (SWA / STA / AWA) and abrasion and oil resistant rubber outer jacket

Features : Reinforced mechanical protection against crushing and abrasion. Less flexible than a soft rubber cable, but better suited to harsh industrial environments.

Standards : IEC 60245, IEC 60502, BS 5467 / BS 6622

ZMS CABLE expert advice :
In mobile installations, an unarmored flexible rubber cable is often preferred for its flexibility. On the other hand, when the cable is exposed to risks of crushing or abrasion, the use of an armored rubber cable is recommended. THE SWA armor are generally chosen for fixed installations requiring high mechanical resistance, while STA is more suitable for multi-conductor cables in industrial environments.

The above values are typical for cables with insulation and rubber sheath, galvanized steel wire armor.

Driver type	Number of conductors × nominal section (mm²)	Driver diameter (mm)	Nominal insulation thickness (mm)	Diameter of armor wires (mm)	Outside diameter of the cable (mm)	Cable mass (kg/km)
Classy driver 2	3 × 10	4,05	1,0	1,6	23,07	1084,29
Classy driver 5	3 × 10	4,12	1,0	1,6	23,22	1088,36
Classy driver 6	3 × 10	4,43	1,0	1,6	23,89	1117,99

Advantages of rubber cables

THE rubber cables stand out for their performance in demanding environments and mobile applications :

Excellent flexibility : flexible rubber cables withstand repeated bending without deterioration, ideal for mobile equipment
High mechanical resistance : good abrasion resistance, to shocks and tensile stresses ; for more severe environments, armored rubber cables offer reinforced mechanical protection
Good resistance to harsh environments : adapted to humidity, oils, to bad weather and external conditions
Large temperature range : reliable operation in variable thermal conditions
Safety and reliability : elastomer insulation (EPR) offering good dielectric properties

Expert council : for environments with high mechanical constraints, it is recommended to opt for a armored rubber cable (EITHER or STA) to improve protection and lifespan.

Rubber cable applications

Thanks to their flexibility and robustness, rubber cables are used in many industrial sectors :

Mobile electrical equipment : power supply of machines, portable tools and construction equipment (H07RN-F widely used)
Construction and construction sites : cranes, lifting machines, temporary facilities
Industry and production : cabling of equipment subject to frequent movements or severe conditions
Energy and infrastructure : temporary facilities, generators, mobile power distribution
Maritime and port sector : humid environments exposed to climatic conditions
Mining : equipment subject to high mechanical stress

Expert council : for applications with frequent movements, favor flexible rubber cables ; for installations exposed to high mechanical risks, choose an armored rubber cable adapted to the environment.

ZMS CABLE expert advice – How to choose ?

The choice between an unarmored EPR cable and an armored EPR cable does not only depend on voltage, but above all real installation conditions.

Choose an unarmored EPR cable when flexibility is the priority, the ease of installation and that the cable is installed in a protected environment, without significant mechanical risks (indoor facilities, cable trays, zones techniques).
Opt for an armored EPR cable when the cable is subjected to mechanical stress, for buried installation or a demanding industrial environment.
Armor provides additional protection essential to guarantee safety, the sustainability and continuity of service of the network.

At ZMS Cable, we recommend always analyze the installation method, the environment and the expected lifespan of the project before defining the final structure of the EPR cable.
