Cables by Type

Railway Transit Cable

Railway transit cables are specialized electrical cables designed for use in railway and transit systems, ensuring reliable and efficient power distribution, signaling, and communication. These cables are engineered to withstand the demanding conditions of railway environments, including vibration, mechanical stress, temperature variations, and exposure to elements. They are essential for the safe and uninterrupted operation of trains, trams, and other rail-based transportation systems.

Railway transit cables are known for their durability, high performance, and safety features. They play a critical role in maintaining the integrity and efficiency of railway networks, supporting a wide range of applications from power supply to data transmission.

Construction

Conductors: Typically made of copper or aluminum, providing excellent electrical conductivity.

Insulation: High-grade materials like XLPE (cross-linked polyethylene), EPR (ethylene propylene rubber), or LSZH (low smoke zero halogen) to withstand high temperatures and mechanical stress.

Shielding: Metallic shielding to protect against electromagnetic interference (EMI) and ensure signal integrity.

Outer Sheath: Durable and flexible outer sheath made of materials like TPU (thermoplastic polyurethane), rubber, or LSZH to resist abrasion, chemicals, and environmental factors.

Additional Protection: Depending on the application, additional protective layers such as flame-retardant coatings or armoring may be included.
