Control cable BiT E-BUS-H 2x2x0.8 EB0080

Control cable for smart building systems

The BiT E-BUS-H cable is a specialized cable designed for transmitting signals in building management systems based on the European Installation Bus (EIB) and KNX standards. It is used to connect sensors and control devices, enabling efficient management of lighting, temperature, air conditioning and other functions in smart installations. This cable is used in both residential and commercial buildings where reliable and safe communication between system elements is required.

Construction and properties

The BiT E-BUS-H cable is characterized by a careful construction ensuring high signal transmission quality and safety of use. It has single-wire copper conductors, insulated with a special halogen-free polymer. The conductors are twisted in pairs, which minimizes electromagnetic interference. Additionally, the cable is equipped with a screen made of metallized foil and an earthing wire to provide additional protection against interference and improve installation safety. The outer jacket is made of a halogen-free, self-extinguishing and flame-retardant polymer, which increases safety in the event of a fire.

• Halogen-free: The use of halogen-free materials minimizes the emission of toxic gases during combustion, which is particularly important in public buildings and places with increased fire safety requirements.
• Fire resistance: The cable meets the PN-EN 60332-1-2 standard confirming its flame-retardant properties.
• Flexibility: The construction with twisted pairs of conductors provides flexibility of the cable, making it easier to install and route in various installation conditions.
• Shielding: A screen made of metallized foil protects against electromagnetic interference, ensuring stable signal transmission.
• Wide operating temperature range: The cable retains its properties over a wide temperature range from -40°C to 80°C, allowing it to be used in various environmental conditions.

Applications and parameters

The BiT E-BUS-H cable is intended for laying in dry and damp rooms, both surface-mounted and concealed – in pipes, cable trays or cable ducts. It can also be used outdoors provided it is protected from direct sunlight. Thanks to its properties, it is perfect for installations of smart building systems requiring reliable communication between devices. The cable has a conductor cross-section of 0.8 mm² and contains 4 conductors. Its wave impedance is 85 Ω ±15%, and the maximum loop resistance is 73.2 Ω/km. The insulation resistance is 100 MΩ x km. The minimum bending radius is 8 x cable diameter, and the operating temperature ranges from -40°C to +80°C with a minimum laying temperature of -5°C.
