Description
The 10KV and 35KV thermal shrinkable busbar protective bushing is an advanced insulating solution designed for high voltage applications. Constructed from radiation cross-linked polyolefin, this continuous tube provides outstanding insulation performance and durability. Ideal for use with electrical bus bars rated up to 36KV, it effectively insulates rectangular, square, and round bus bars, inline bolted connections of bus bars, and various switchgear configurations. Its features make it suitable for copper and aluminum bus bars in metal-clad switchgear, metal-enclosed bus bars, and substation switchgear.
