Specifications
The document details the specifications for a bus cable, specifically the VOKA EIB Bus 2x2x0.8 Cca, designed for use in KNX/EIB bus systems. The cable has a diameter of approximately 6.2 mm, a cable weight of 64 kg/km, and a copper index of 21 kg/km. It is approved for indoor installation and complies with euroclass classification Cca.

Application
The cable is intended for use in bus systems and ICA cable power installations. It can be laid in or on plaster, including in moist and wet rooms, but is not approved for power and underground installations.

Standards
The cable adheres to the EIB/KNX-guideline.

Construction
The cable features a solid, bare copper conductor with a diameter of 0.8 mm. The core insulation is made of PVC, with a core diameter of 1.45 ± 0.05 mm. Core identification colors include white, yellow, red, and black. It has a plastic-laminated aluminum foil screening and a special PVC sheath in green (RAL 6017).

Behavior Under Fire Conditions
The cable meets the standards EN 60332-1-2, EN 50399, EN 50575, and EN 13501-6 class Cca-s3 d2 a3.

Chemical Properties
The cable complies with RoHS 2011/65/EU.

Electrical Characteristics
The loop resistance is a maximum of 73.2 Ω/km, insulation resistance is a minimum of 100 MΩ x km at +20°C, operating capacity is nominally 100 nF/km, and capacitive coupling K1 is nominally 200 pF/100m. The test voltage is 1500 V/AC, and the operating voltage is 300 V.

Thermal & Mechanical Properties
The temperature range for stationary use is -30°C to +70°C, and during installation, it is 0°C to +50°C. The minimum bending radius when installed is 5 times the diameter, and when moved, it is 10 times the diameter. The maximum traction is 100N.
