LAPP ÖLFLEX® UNIPLUS 1X25 BK – 4521011U100 is a reliable 25 sq. mm single-core electrical cable designed for electrical wiring, power distribution and suitable fixed-installation applications. Manufactured by LAPP, this cable belongs to the ÖLFLEX® UNIPLUS family and is designed to provide dependable electrical performance along with convenient handling and installation.
The product features a single 25 mm² conductor and is identified by LAPP article number 4521011U100. The BK designation refers to the black colour of the cable. Its single-core construction makes it suitable for electrical systems where individual conductors are routed separately between electrical components, terminals, distribution points and other equipment.
The cable incorporates a fine-wire bare copper conductor with Class 5 construction according to IEC 60228. This conductor design provides good electrical conductivity while offering the flexibility needed for easier cable routing and installation. The flexible construction can be especially useful inside electrical panels and cabinets where conductors need to be routed around breakers, terminals, contactors and other electrical components.
The conductor is protected with PVC insulation, which provides electrical separation and helps protect the copper conductor from accidental contact with surrounding conductive components. PVC is widely used for industrial electrical cables because of its practical combination of insulation performance, durability and ease of installation.
The 25 mm² copper conductor is one of the main characteristics of this ÖLFLEX® UNIPLUS cable. A 25 mm² conductor can be used in electrical applications where the required conductor size is greater than that of conventional smaller wiring.
The fine-wire construction provides greater flexibility during installation. This can help installers route the cable through suitable electrical ducts, control cabinets and protected installation paths without unnecessary difficulty.
The actual permissible current-carrying capacity depends on several installation factors, including installation method, ambient temperature, conductor grouping and applicable electrical regulations. Therefore, the cable should always be selected based on the complete electrical design of the installation.
The LAPP ÖLFLEX® UNIPLUS 1X25 BK uses PVC insulation around the copper conductor. The insulation provides the necessary electrical separation between the conductor and external components.
It also helps protect the conductor during normal handling and installation. The black insulation gives the cable a consistent appearance and allows it to be easily identified within an electrical wiring system.
The ÖLFLEX® UNIPLUS range is designed for applications with a 1.1 kV AC RMS nominal voltage rating, making the cable suitable for compatible low-voltage electrical installations.
The specified voltage rating allows the cable to be considered for various industrial wiring and electrical distribution applications where the electrical requirements correspond to the cable specifications.
Before using the cable in a particular installation, the complete system should be checked for voltage, current, temperature, environmental conditions and applicable standards.
The ÖLFLEX® UNIPLUS range incorporates flame-retardant characteristics according to the applicable specifications for the product family.
Flame-retardant cable construction is an important consideration in many industrial electrical installations because it is intended to help limit flame propagation along the cable under specified test conditions.
This makes the cable suitable for consideration in applications such as electrical panels, switchgear cabinets, industrial wiring systems and protected installation routes where flame-retardant properties are required.
The single-core design allows the cable to be used in installations where individual conductors are required rather than a multi-core cable assembly.
The fine-wire Class 5 copper conductor provides flexibility, which can make the cable easier to handle during:
The cable should be routed while maintaining the manufacturer's recommended bending radius and avoiding excessive mechanical stress.
The ÖLFLEX® UNIPLUS 1X25 BK can be used for suitable electrical wiring inside control panels and cabinets. The flexible conductor makes it convenient to route individual wires between electrical components.
Typical panel applications may include connections between:
Proper cable sizing and termination practices should always be followed according to the electrical system requirements.
