Installation cable (N)YM-O 500V 2x2.5 mm², coils of 50 m (N)YM-O5-2X2,5

(N)YM-O cable is an indispensable component of every electrical installation, whether in residential or commercial buildings. This two-core cable with a cross-section of 2.5 mm² is designed for the safe transmission of electrical energy in circuits with a rated voltage of 500V. Supplied in practical 50-meter reels, it simplifies installation and minimizes material waste.

Construction and Application

The (N)YM-O cable features a round design with Class 1 copper conductors (solid core), ensuring flexibility and ease of routing. The conductors are twisted for enhanced protection against mechanical damage. Insulation made of polyvinyl chloride (PVC) guarantees high resistance to external factors and ensures safe operation. The outer sheath, also made of PVC, protects the cable against moisture, abrasion, and UV radiation. This cable is widely used in building electrical installations, both indoors and outdoors, provided it is protected from direct sunlight. It performs excellently in lighting circuits, socket circuits, and powering electrical devices.

Key Features and Benefits

• Versatility: Suitable for use in electrical installations of all types—from residential to industrial.
• Safety: Rated voltage of 500V and PVC insulation ensure safe operation.
• Flexibility: Class 1 copper conductors facilitate cable routing even in confined spaces.
• Durability: Resistance to mechanical and chemical factors guarantees a long service life.
• Convenient Installation: Supplied in 50-meter reels—minimizes material waste and speeds up installer work.
• Optimal Dimensions: Conductor diameter of 8.3 mm and approximate outer diameter of 8.3 mm provide optimal parameters for this cross-section.
• Color Coding: Colored conductor identification simplifies correct wiring during installation.

Operating Parameters and Compliance with Standards

The (N)YM-O cable is designed for operation in ambient temperatures ranging from -5°C to +50°C, with a maximum allowable conductor temperature of 70°C. The minimum bending radius during fixed installation is 49.8 mm, ensuring the cable’s integrity and electrical performance. Fire reaction class is Eca according to EN 13501-6—indicating limited flammability and low smoke emission in case of fire. The absence of armor or shielding makes this cable suitable for applications where strong electromagnetic interference or external mechanical damage protection is not required.
