Railway cable; 2X1; EN 50264-3-2; Type MM; U0/U: 300/500 V; -40 – +90 °C; Halogen-free compound;
Benefits
- For the protection of people and property.
- Insulation integrity for up to 120 minutes under the effect of fire (classification PH120 according to DIN EN 50200). Guarantees functional integrity and power supply in the event of an emergency.
- Compliant with standards for use in railway vehicles: fire safety and cable design requirements according to DIN EN 50264-3-2, type MM; fire behaviour in accordance with DIN EN 45545-2, hazard level HL3.
- The cross-linked insulation and sheath materials promote longevity at high temperatures or with a high current load, and provide high dielectric strength.
- Halogen-free and highly flame retardant materials reduce the risk of flame propagation, high smoke density and toxic smoke in the event of a fire.
- Space-saving due to reduced wall thicknesses.
Applications
- For wiring safety-related components in railway vehicles.
- Typical application areas are emergency power circuits for alarm, lighting and communication purposes, which must maintain their function for a certain period of time in the event of a fire.
- For use in railway vehicles, for fixed installation and applications where limited movement is to be expected.
- Can be used in dry and damp conditions, and especially in harsh and oily environments.
- The cross-linked polymer compound is highly resistant to oils, fuels, alkalis and acids.
