ÖLFLEX® - Single and Control Cable

ÖLFLEX® is the first branded cable in the world. In 1959, Oskar Lapp – the founder of LAPP developed the first flexible, industrially manufactured control cable with color coded wires. He and his wife Ursula Ida Lapp named the oil-resistant and flexible cables ÖLFLEX®. Today, ÖLFLEX® is a brand synonymous with power and control cable. Their single and multicore cables are the most widely used cables in the world.

LAPP as a leader in cable and connection technology has ensured that under ÖLFLEX® brand, we have a wide range of power and control cables to meet the requirement of various industries. 

Application Areas

- Industrial machinery, machine tools, plant, and equipment engineering

- Measurement, control, heating, and air conditioning systems

- Wind power and photovoltaic systems

- Public buildings, airports, and railway stations

- Medical technology, chemical industry, composting plants, and sewage works

- Food and beverage industry

- Power drive systems

- Robot applications

- Railway applications


- Flexible- Suitable for fixed, flexible, and highly flexible (energy chains) applications. The cable can be bent, twisted longitudinally, winded and unwinded. Flexible cables are used in industrial applications with moving machines parts, production lines, robots, and wind turbines. All ÖLFLEX® cables are flexible, and certain cables can be bent occasionally while others can be bent multiple times.

- Oil resistant- Oil in industries serves as a coolant and/ or a lubricant. The plasticizers in the wires attract oils and can be absorbed by the polyolefin. The oil then extracts the plasticizers from the PVC present in the protection jacket, causing it to crack or swell. This leads to a potentially dangerous condition. ÖLFLEX® has numerous cables with varying degrees of oil resistance

- UV resistant- Wires and cables with extra UV protection are necessary for areas where they are exposed to strong sunlight containing UV rays. Over the years, high-energy UV rays break down the protection plastic and can attack the secondary insulated layer of the cores. LAPP has a wide range of UV-resistant wires that are usually black. It is because the plastic sheath contains soot, which can absorb UV rays and convert them into heat.

- Flame retardant and low smoke- Fire mishaps are extremely common in industries and residential/ commercial buildings. Research studies suggest that one-third of fires originate inside the building. ÖLFLEX® cables are constructed with thermosetting and insulated armour that have low smoke to minimize the risk from toxic fumes in case of a fire.

- Fire survival- ÖLFLEX® cables are used for data recovery during fire crisis management. These are used in running emergency systems during a fire as they have a predefined time period of 90, 120, or 180 minutes.

- Halogen-free- Halogens can damage health, especially when the cables are exposed to fire. Halogen-free cables are made with a composition that does not contain halides like chlorine, and fluorine etc. Halogen-free cables are instead made of silicone rubber, polyethylene, polyurethane, or ethylene propylene diene rubber. These cables do not emit any corrosive gases when exposed to fire.

- Fulfils the most demanding requirements for chemical and mechanical properties

- ÖLFLEX® heat product range has cables and wires that can withstand high temperatures from -195 to +400 degrees Celsius and up to +1565 degrees Celcius.

- Suitable for weather-resistant and waterproof installations and waterproof connections (Ingress Protection IP55 to IP69K).

ÖLFLEX® single and multicore cables have copper conductor and PVC insulation. However, we also provide outer jackets in Polyvinyl Chloride (PVC), Polyurethane (PUR) and Rubber based on application and environment. The cables are tested and certified with international licenses (like UL & CSA Approval).

  • The key difference between single-core and multicore cables lies in the total number of conductors. A single core cable is manufactured with a single conductor. On the other hand, multicore cables have more than one conductor, but the final number depends on the variant specification. The individual cores can either be solid, shielded, or braided core.
  • 5 core cables are used in low voltage transmissions. It is commonly used in public and domestic wiring settings. The five core cables are color-coded in blue, red, black, green, or white/ yellow/ grey for easy identification.

  • The answer lies in its name. A multicore cable combines multiple signals or power feed within its single shielded structure. It has Polyvinyl Chloride (PVC), Polyurethane (PUR) or a Rubber shield that provides the cable with protection, making it suitable for sturdier working conditions.

  • Certain appliances and electric systems necessitate the use of multicore cables because of high power demands that may lead to harsher working conditions, more wear and tear, high operational stress, and difficulty in installation. Thus, multicore cables are more commonly used in such situations.

  • A multicore flexible cable is made up of a highly flexible copper conductor. It has a specially formulated protection layer of Polyvinyl Chloride (PVC), Polyurethane (PUR), making it more flexible.

  • Single core cables are widely used for wiring purposes at homes, shops, and buildings. They are also used in an un-shielded form in computers and power control panels. Their purpose is to successfully supply electricity from the power mains to the required location.

  • Flexible cables are designed to be bound tightly or when undergoing high physical stress, commonly found in moving applications. Common applications that use flexible cable are cranes, conveyors, heavy-duty equipment, cable carriers, mobile motors, or generators, etc.

  • It becomes quite clear from the name that the cable type uses a single copper conductor. It is a common misconception that single-core cables are more flexible than multicore cables. Their flexible nature depends on the thickness, gauge and whether it has been shielded or not. These factors come into play depending on the requirements for the device in the application. It is also noted that large diameter cables are comparatively less flexible than small-diameter ones.

  • 3 core cables have 3 conductors and are required in applications that are to be earthed. The 3 cores are named live, neutral and earthing wires.

  • As the name suggests, a 4 core cable has 4 cores inside it. It is commonly used to supply electric power from the mains to the applications and networks locally.
