    Protect Busbars Reduces Distances - A New Heat-Shrink Tube Up To 36kV

    Uploaded by

    Amit Bhatia
    The document summarizes heat-shrink tubing called SRBB that can be used for insulating busbars in indoor and outdoor substations up to 36kV. The tubing is made of cross-linked polyolefin, comes in various sizes from 19-120mm diameters with wall thicknesses ranging from 6-40mm. It has properties like being halogen-free, UV resistant, and resistant to fungus/decay. Minimum clearance distances between busbars are provided depending on voltage level and whether busbars have insulation between phases and ground.
