LAPP ÖLFLEX® UNIPLUS 1X25 GNYE – 4521001U100 is a high-quality 25 sq. mm single-core electrical cable designed for reliable electrical wiring and fixed-installation applications. Manufactured by LAPP, this cable belongs to the ÖLFLEX® UNIPLUS range and is developed for professional electrical installations where dependable conductivity, flexible handling, effective insulation and flame-retardant performance are required.
The product features a single 25 mm² conductor and is identified by LAPP article number 4521001U100. The GNYE designation refers to its green/yellow colour combination, making it particularly suitable for wiring applications where green/yellow conductor identification is required according to the applicable electrical installation practices.
The cable uses a fine-wire bare copper conductor according to IEC 60228 Class 5 and IS 8130-1984. This conductor construction combines good electrical conductivity with flexibility, allowing the cable to be conveniently routed and installed in suitable electrical systems. LAPP specifies the conductor as fine-wire Class 5 construction. LAPP
The conductor is surrounded by PVC insulation, which provides electrical insulation and protects the copper conductor from accidental contact with surrounding conductive components. The cable is designed for a 1.1 kV AC RMS nominal voltage and has a 3 kV test voltage, making it suitable for compatible low-voltage electrical installations. LAPP
The green/yellow colour is one of the key identifying characteristics of this product. The conductor is manufactured with a two-coloured green/yellow identification, making it easy to distinguish from other single-core conductors within an electrical installation.
This makes the cable particularly useful where conductor identification is important for organized electrical wiring. The colour should, however, be used according to the applicable electrical codes and installation standards rather than simply for general circuit identification.
The 25 mm² conductor size provides a relatively large conductor cross-section for electrical wiring applications where the required conductor sizing calls for a 25 mm² cable.
The cable incorporates a fine-wire bare copper conductor manufactured according to IEC 60228 Class 5. Fine-wire construction provides flexibility compared with rigid conductor designs, making the cable easier to handle during installation.
This can be particularly useful when routing conductors through:
The copper conductor provides good electrical conductivity, while its flexible construction facilitates cable routing and termination.
The actual current-carrying capacity should always be calculated according to the installation method, ambient temperature, grouping conditions and applicable electrical standards. LAPP identifies current rating for this product family according to IS 3961. LAPP
The LAPP ÖLFLEX® UNIPLUS 1X25 GNYE uses Polyvinyl Chloride (PVC) as the core insulation material.
PVC insulation provides the electrical separation required between the copper conductor and surrounding components. It also helps protect the conductor during normal handling, installation and operation.
The combination of a fine-wire copper conductor and PVC insulation creates a practical single-core cable solution for a variety of fixed electrical wiring applications.
LAPP specifies this product family as a PVC-insulated single-core cable with a nominal voltage of up to 1100 V according to the applicable Indian standard. LAPP
The ÖLFLEX® UNIPLUS 1X25 GNYE is rated for a 1.1 kV AC RMS nominal voltage. This makes it suitable for compatible low-voltage electrical installations where the cable's voltage rating matches the requirements of the system.
The cable also has a specified 3 kV test voltage, supporting electrical insulation testing and quality verification.
For every installation, the complete electrical system should be evaluated for voltage, current, installation conditions, temperature and applicable safety requirements.
The ÖLFLEX® UNIPLUS cable range is designed with flame-retardant characteristics. LAPP specifies flame retardance according to IEC 60332-1 and IS 10810-53 for the relevant product family. LAPP
Flame-retardant characteristics are particularly relevant in electrical installations where multiple conductors are routed together. The cable is designed to help reduce the risk of flame propagation under the specified test conditions.
This makes the cable suitable for consideration in electrical panels, switchgear cabinets, distribution boxes and other appropriate industrial wiring environments.
The LAPP ÖLFLEX® UNIPLUS 1X25 GNYE is designed primarily for fixed installation, while the product family also specifies suitable flexible installation applications within its stated conditions. LAPP
LAPP specifies the following bending-radius requirements for this product family:
Following the manufacturer's recommended bending radius helps prevent unnecessary mechanical stress during cable installation.
The ÖLFLEX® UNIPLUS range is designed to operate across a specified temperature range depending on the installation condition.
For fixed installation, LAPP specifies a temperature range of approximately -40°C to +80°C. For occasionally moved applications, the specified range is approximately -15°C to +70°C. LAPP
These temperature specifications should be considered together with the actual environmental and electrical conditions of the installation.
The cable is designed for wiring applications such as:
Suitable for appropriate wiring inside electrical control panels where a 25 mm² single-core conductor is required.
Can be used for compatible connections within switchgear cabinets and electrical distribution assemblies.
Suitable for wiring applications inside appropriate distribution boxes.
Can be used in suitable industrial electrical systems where the cable's technical specifications meet the project requirements.
LAPP specifies the cable for suitable installation in tubes.
The cable can be used in appropriate closed installation ducts.
Suitable for protected electrical installation environments as specified by the manufacturer.
LAPP specifically lists wiring of lamps, devices, switchgear cabinets and distribution boxes among the applications for this product family. LAPP
Provides a 1 × 25 mm² conductor configuration for electrical applications requiring this conductor cross-section.
The green/yellow two-colour identification makes the conductor easy to distinguish within an electrical wiring system.
The bare copper conductor provides good electrical conductivity while the fine-wire construction provides installation flexibility.
Class 5 fine-wire construction provides improved flexibility for practical cable routing.
Provides reliable electrical insulation around the copper conductor.
Designed for compatible low-voltage electrical installations up to the specified nominal voltage.
Provides the specified electrical test voltage for insulation verification.
LAPP specifies flame-retardant performance according to applicable standards including IEC 60332-1 and IS 10810-53. LAPP
The fine-wire conductor makes the cable easier to route and handle during installation.
