    CY-L Copper Sandwich Busway System

    The CY-L series busway features a fully enclosed, integrally molded housing that minimizes internal dust accumulation and is finished with an electrostatic polyester powder coating. It overcomes the weak joint protection typical of all-aluminum busways, providing full-system IP66 protection and excellent corrosion resistance.

    With its flame-retardant properties (non-combustible in external fires) and IP66 rating, this sandwich-style busway is well-suited for complex and dynamic power distribution environments.

    An integrated grounding bus (IGB) design offers a ground conductor with 50% phase-line capacity, ensuring reliable grounding continuity and integrity. Under high-capacity ground faults, the system remains secure while reducing eddy current losses.

    The housing is assembled with Dacromet-coated rivets at minimal spacing, delivering high short-circuit resistance, improved safety, and elimination of electrical shock risks.

    Service Life:Up to 30 years
    Protection Rating:  IP54, IP65, IP66
    Conductive Materials:  99.95% Copper
