Description
This 22AWG 3 pair screened control cable is a Belden 8777 equivalent, designed for low voltage signal, audio and control applications. It is commonly used in BMS, HVAC systems, and general instrumentation wiring where stable signal transmission and basic screening are required.
The cable is constructed with stranded tinned copper conductors and HDPE insulation, providing good electrical performance and flexibility for installation. An overall aluminium foil screen with drain wire helps reduce interference from nearby electrical circuits, making it suitable for use in typical commercial environments.
The LSZH outer sheath is rated to Euroclass Eca, supporting use in public buildings where reduced smoke and halogen emissions are specified.
