LAPP ÖLFLEX® UNIPLUS 1X70 BK – 4521014U100 is a high-quality 70 sq. mm single-core electrical cable designed for reliable power transmission and electrical wiring applications in industrial and commercial installations. Manufactured by LAPP, this cable belongs to the trusted ÖLFLEX® UNIPLUS cable range and is designed to provide dependable electrical performance, flexibility and easy installation.
The 1X70 BK designation indicates a single-core cable with a 70 mm² conductor cross-section, while BK represents the black colour of the cable. The product is identified by LAPP article number 4521014U100, making it easy for electrical contractors, panel builders, system integrators and industrial procurement teams to identify and source the required cable.
The cable is constructed using a fine-wire bare copper conductor, providing good electrical conductivity along with the flexibility required during installation. The conductor construction is based on IEC 60228 Class 5, which makes the cable easier to route and handle compared with rigid solid conductors of the same cross-sectional area. This is particularly useful when cables need to be routed through electrical panels, cabinets, ducts or other confined installation spaces.
The conductor is protected by a PVC insulation layer, which provides electrical insulation and helps protect the conductor during normal operating conditions. The PVC insulation is suitable for a wide range of industrial wiring applications and contributes to the cable's overall mechanical and electrical reliability.
With a nominal voltage rating of 1.1 kV AC RMS, the LAPP ÖLFLEX® UNIPLUS 1X70 BK is suitable for various low-voltage electrical power and wiring applications. The cable also has a 3 kV test voltage, supporting the required level of electrical insulation testing during manufacturing and quality verification.
One of the key advantages of the LAPP ÖLFLEX® UNIPLUS 1X70 BK is its combination of a large 70 mm² copper conductor and flexible conductor construction. A larger conductor cross-section is commonly used where electrical installations require higher current-carrying capability, subject to the applicable installation conditions, ambient temperature, grouping and permissible current requirements.
The bare copper conductor provides an efficient path for electrical current, while the PVC insulation helps prevent unwanted electrical contact between the conductor and surrounding components. This makes the cable suitable for use in organized electrical wiring systems where reliable insulation and proper cable routing are essential.
For industrial installations, selecting the correct cable size is important for maintaining electrical safety and system performance. The 70 mm² conductor size makes this cable suitable for applications where smaller cross-section cables may not meet the installation requirements.
The fine-wire Class 5 copper conductor is an important feature of this LAPP cable. Compared with rigid conductors, fine-wire construction provides greater flexibility and makes the cable easier to bend and route during installation.
This characteristic can be particularly beneficial in:
The flexibility of the conductor can also help installers achieve cleaner and more organized cable routing, especially where space inside electrical cabinets is limited.
The cable uses PVC insulation, which provides the necessary electrical separation between the copper conductor and the surrounding environment. PVC is widely used in industrial and electrical cable applications because of its practical combination of insulation properties, durability and cost effectiveness.
The insulation also helps maintain the cable's electrical performance during normal operating conditions and protects the copper conductor from accidental contact with other conductive components.
The ÖLFLEX® UNIPLUS range is designed with flame-retardant properties according to applicable standards specified for the product family. Flame-retardant cable construction is an important consideration for electrical installations because it helps limit the propagation of flame along the cable under specified test conditions.
This makes the cable suitable for applications where electrical wiring needs to meet specified flame-retardance requirements.
However, the cable should always be selected and installed according to the applicable electrical regulations, installation standards and environmental requirements of the particular project.
The LAPP ÖLFLEX® UNIPLUS 1X70 BK is primarily suitable for fixed installation applications. It can be used for electrical wiring in locations such as control cabinets, switchgear systems, distribution boxes and protected installation routes.
Its round construction and flexible fine-wire conductor allow installers to route the cable conveniently while maintaining the manufacturer's recommended bending radius.
For fixed installation, the recommended minimum bending radius should be observed during installation to avoid unnecessary mechanical stress on the cable.
The cable is particularly useful for professional electrical installation work involving control panels, switchgear cabinets and distribution systems.
In an electrical panel, cables need to be routed neatly between terminals, breakers, busbar systems, contactors and other electrical components. The flexibility of the fine-wire copper conductor can make termination and routing more convenient.
The black insulation also provides a professional appearance and can be used according to the colour identification system followed by the electrical installation.
The LAPP ÖLFLEX® UNIPLUS 1X70 BK can be considered for a wide range of industrial and commercial electrical applications, depending on the project's voltage, current, environmental and installation requirements.
Typical applications include:
1. Electrical Control Panels
Used for internal electrical wiring and power connections within suitable control panel systems.
2. Switchgear Cabinets
Suitable for wiring and connections in industrial switchgear and electrical distribution assemblies.
3. Distribution Boxes
Can be used for power distribution wiring where the required conductor cross-section and voltage rating match the application.
4. Industrial Machinery
Suitable for fixed wiring and electrical connections in industrial equipment where the cable's technical specifications meet the machine's requirements.
5. Electrical Installation Systems
Can be installed in suitable tubes, ducts and protected installation routes according to applicable installation requirements.
6. Power Distribution Applications
The 70 mm² copper conductor makes the cable suitable for applications requiring a larger conductor cross-section, subject to proper current-carrying calculations.
The LAPP ÖLFLEX® UNIPLUS 1X70 BK – 4521014U100 combines a large 70 mm² copper conductor, flexible Class 5 construction, PVC insulation and a 1.1 kV voltage rating to provide a practical solution for demanding electrical wiring requirements.
Its flexible conductor construction helps simplify cable routing, while the PVC insulation provides the electrical separation required for safe and reliable wiring. The cable's flame-retardant characteristics and suitability for fixed installations make it a practical option for industrial electrical systems where dependable cable performance is important.
For panel builders, electrical contractors, OEMs, industrial maintenance teams and system integrators, this LAPP single-core cable can be used wherever its technical specifications match the electrical and environmental requirements of the installation.
