Control cable BiT 500 (St) CH 56x1.0 SB9800

Shielded Control Cable BiT 500 (St) CH 56x1.0

This flexible, multicore control cable, BiT 500®(St) CH, is designed for indoor and outdoor applications. It features dual shielding—aluminum foil and copper braid—ensuring high immunity to electromagnetic interference. This cable is particularly recommended for installations requiring reliable transmission of control signals and power.

The cable features a halogen-free construction, enhancing safety and minimizing the emission of toxic substances in case of fire. Conductors are numbered for easy identification, and their flexible design facilitates installation even in confined spaces. The cable complies with stringent standards for fire resistance and low smoke emission, guaranteeing installation safety.

Construction and Properties

• Shielding: Dual shielding (foil + braid) minimizes electromagnetic interference, ensuring stable signal transmission.
• Halogen-free: Materials used contain no halogens, improving fire safety and reducing emission of toxic gases during combustion.
• Fire resistance: Complies with IEC 60332-1-2 and IEC 60332-3-24 (Category C), ensuring high safety levels in fire conditions.
• Low smoke emission: Compliant with IEC 61034-2, ensuring limited smoke emission during combustion, improving visibility and facilitating evacuation.
• Conductors: 56 conductors, each 1 mm² cross-section, made of copper, flexible for easy installation.
• Conductor insulation: Insulation material ensures reliable operation across a wide temperature range (-40°C to +80°C).
• Application: Ideal for control installations in industrial and commercial buildings and automation systems.
• Conductor resistance: 19.5 Ω/km at 20°C—ensures efficient current transmission with minimal energy loss.
• Bending radius: Minimum bending radius is 225 mm for mobile installations and 112.5 mm for fixed installations—facilitating routing even in tight spaces.

Technical Parameters

The BiT 500 (St) CH 56x1.0 cable is rated for nominal voltage up to 500 V (300/500 V). Fire reaction class is Dca, and acidity class a1 confirms its high quality and safety. Thanks to its common shield, the cable is resistant to external interference, which is especially important in industrial environments exposed to strong electromagnetic fields. Cable weight is approximately 885 kg/km, with an approximate outer diameter of 22.5 mm—these parameters must be considered during electrical installation design.
